Squeaks

All suspension bikes seem to be more vocal than hardtails irrespective of bushes or bearings. Carbon frames tend to highlight this by amplifying the sound of any small thing sufficiently that everyone around me complains.

I have been trying a range of different bearings to find something Stanmerproof.

Bearings have a code that determines size and shielding etc. but quality is a little more difficult to measure. Most bearings use caged balls but some are double row which means tiny ball bearings. These need good seals to repel the mud. I examined several different types of bearings before fitting and found the grease quantity varied, the seal edge gap was different and the smoothness of the bearing when turned in your fingers even changed between manufacturers.

I fitted the metal shielded bearings first and ran them for a while. The seal was much better than I expected and there was no impact damage from jammed mud or stones on the outside. The main fault was wear even with a full grease quantity. Any water penetration killed them quite quickly though. I ran two sets to find an average and give a B.

I tried the rubber shield bearings next which are more common (but the same price). I expected the seal to be better and some physical damage but found the seals to be poorer and lifetime was reduced. Photo shows the condition with the seal removed. As the seals were poorer these get C.

I have had three different suspension bikes and all of them need servicing before you think necessary to keep them running smoothly. I strip and clean the bike frequently including removing the fork and removing links and triangles and this forces me to check the bearings. You can check yours by removing the air from the shock, perhaps the shock itself and move the rear end with the wheel removed. If it is not super smooth it needs fixing.

Some older bikes need specialist tools, some newer ones supply links with bearings fitted which is a quicker change. Changing bearings is usually a mid range technical job on a bike to allow for using a drift and a bearing press or vice. Damage is easy if your hammer is near the top of your tool box.

As nothing is Stanmerproof yet I am now running some more expensive bearings (SKF) and my bike is now quieter and even surprised a badger last week by sneaking up behind him without an alarming squeak. I will update this report as soon as it begins to squeak again but hoping to give them an A this time.

Brake pads

I have been trying different brake pads over the last few weeks as I bought some ceramic pads (Brake Authority) just to try. I fitted ceramic to the rear and left original sintered on the front. I did try and bed the pads correctly by entertaining the small children in the street by riding up and down braking repeatedly and feeling a little foolish.

On riding the rear brake was great. Late braking with a slew was easy and the additional ‘bite’ was useful when misjudging a corner. Changing ceramic to the front was more difficult and threw me over the bars first time. Braking was improved but tyre adhesion became critical and I had to change tyres to feel safe. I had to brake harder on the rear to balance with the ceramics and that caused the brakes to wear quickly, about twice as fast as usual.

I have now tried new sintered pads on the rear to estimate wear but I like the ceramic pads. Rotor wear looks minimal, wet squeal is about the same, pad wear seems excellent, initial bite is not too severe and modulation within reasonable expectations but that may be my brakes too.

Photos show difference in wear and if your pads look like the first you are changing them a little late as my braking had disappeared by this stage.

So apologies if you have been riding behind me and I have using just the front brake or just the rear or sliding uncontrollably on every corner however the answer may be to buy new pads and ceramic may be worth a little extra.

Saturday Play Day

Dry conditions and a few keen faces are all that is required to make a day of obstacles and jumps. I started with corner radius and faces turned. ” I ride a bike, I know corners! the faces said”

We then did berms for checking the correct lines and put the two together. Amazingly everyone improved going around corners without late braking. Hurrah less maintenance. A few unknown riders rode past displaying the object of the lesson and faces smiled with their newly revealed skills.

Next was tight corners and reading the real trail. Everyone eventually got that the trail is 3D and not the middle of the flat bit on the ground. Everyone improved again.

Moving on the bike next. Stand up, lean back to unweight the front, do not fall off over logs. A bigger rollover and everyone got faster and seemed to feel the advantage of moving the bike and leaving the saddle.

We ran the whole trails with everything joined up and we all got better; especially me.

Little jumps and my favourite tiny log. We covered all the basics of landing front wheel, back wheel and flat and eventually moved up a little in height. Within an hour everyone had earned their wings. Some were better at steering, some in the air and some got the acceleration knack easier but everyone got big air.There were a slip and mishap and a squeal of brakes and one tumble. Chris jumped really high, really high!, landed and then tumbled towards a tree. He missed the tree but rolled over on the ground with a helmet dent and a graze on the shoulder. This was really my mistake as I should have curtailed his enthusiasm a little but he was a really fast improver and learned to jump high very quickly.

Everyone completed a few more bits including overcoming the Witches Table and Tank traps before turning for home.

Next stage for everyone will be advance training in tailwhips, gaps and somersaults presumably. I will try and arrange something as a group event with Jimbo on this shortly and ask him for a discount day special.

Last ride of summer?

Starting at the carpark with over 20 riders was a bit daunting, but fear of getting left behind was soon alleviated once we got going.

The pace was fairly relaxed and there were plenty of stops (with headcounts) to make sure everyone had caught up. It was great to ride with such a big group and there were smiles all round.

The trails were amazing, and different from my normal haunt of Friston. Stanmer is much more ‘pedally’ throughout the ride, and many of the corners are tighter.  Friston tends to be a long slog up – get your breath – hurtle down – repeat (though his is changing with new trails such as Dave Knows Best / Fearnes Creek). If you ride Stanmer at night I’d recommend a helmet lamp over a bar-mounted one (or both).

The conditions tonight were surprisingly good. Much drier than I expected. This meant that the tree roots were not slippery. Stanmer is VERY rooty, so this ride would have been tougher in the wet.
I never felt hurried and never got lost, even though I ‘felt’ lost for most of the ride.

I’ll certainly come back for more, but next time on my rigid singlespeed.

Thanks guys. Epic evening!

Big Dog2012

Photos from the event are available from russgillespie.co.uk.

I had booked my solo entry for Brighton Big Dog 6 hour months ago because I’d had such a good race last year, achieving a surprise 5th place on a rigid singlespeed! Recently I had been feeling some doubt on how well I could do after a poor performance at Bontrager 24:12 and I had been struggling with motivation to train properly.
I arrived in Brighton friday afternoon, and rode a practice lap with my good friend Ronnie, from the Brighton Mountain Bike Club, he has always supported my racing and encouraged me to set my sights higher than I imagined I could. The practice lap was slippery and slow going, so my nerves were on edge and I was dreading another potentially boggy race! I’d chosen to race geared for the first time in years due to the lack of single speed class, I must say a big thanks to Scott Swalling for lending me the geared wheel, I would have struggled on the wet root sections if I’d ridden single speed.
Saturday morning arrived and I was feeling calm and more relaxed after the bad weather I had expected had not arrived. Lining up for the start I spotted the usual fast faces I have come to recognise, therefore starting the race I decided a top 10 finish was the race aim.
After an unusual short two lap warm-up, the race started. I felt ok off the start, remembering to keep my head and not take any silly risks and as the first lap progressed I was out on my own, behind the lead group, but in-front of the main race group, I was happy with my position as the course still felt slippery, and a few uphill sections remained difficult to clear without stalling.
The second lap felt much better, the course was clear of riders and the slippy patches had started drying and sections I had ran the lap before where now ridable and the singletrack was fast and flowing. The third and forth laps were within +/- 1minute of each other, and I was feeling good, clearing the technical climbs and enjoying the course.
Come the seventh and my last lap I still felt good and had an out-side chance of catching 5th place, I attacked every climbing trying to make up 4minutes. Unfortunately it wasn’t to be, I finished 6th overall, with the fast guys still in front, despite this I feel it was one of my best races despite the lack of podium, trying to compete against semi-pros on my 25pound, steel framed bike with nine gears is always going to be a compromise on a fast course, hilly course, but it’s given me the encouragement I need to make steps next year to progress into being one of the fast guys.
I always enjoy going back to Brighton and I it was an opportunity to meet new face in the bike scene, including Sarah from Halo Headband, thanks for the sponsorship and the words of encouragement from the Brighton Mountain Bike Crew.

With regard to the Bigdog all I can say is that it was once again an enjoyable if painful day out. The course is superb for what is essentially an XC race, really well organised and there is a fantastic atmosphere. I am happy as I know I was a bit quicker than last year, as although my times are about the same I know the course was running about 4-5 minutes slower. It was also fun overtaking people rather than being overtaken. I think my only real mistake was getting caught at the back at the start as there was some big bottle necks not only over the first few climbs but also down the first few descents as people were unsure of the slippery conditions. Next time I will have to make sure I hustle to the middle of the pack at the start. Me and Alan (team Brighton Explorers no.207) did ok finishing 50th, with a slightly better start we might have had an outside chance of another lap but to be honest I am not sure if my legs would have done it anyway. All in all great fun and time to start ‘training’ for next year. (Tom)

Considering we only entered 3 weeks ago, we were chuffed with our performance. I had laps of 57, 58 and 1.00 bang on. Tom had a first lap amongst the massed of 1.00 and then got into the rhythm of 53 and 54.
I fell off three times. Twice on the first lap and once on the second. I managed not to fall off in the third lap, despite riding into a tree. All in all, an excellent day! (Alan)
Had a really fun race! We lost Rich from our team so moved into the very competitive male pairs class, and neither of us have the XC race fitness to come close to podiuming. My tactic was to blast out fast on the first lap, as I can go pretty quick for about ten minutes, which worked beautifully, right up until ‘Badger’s Plunge’ when a flint slashed open my rear tyre and I spent 12 minutes fighting with anchovies and goo getting it to reseal. That put me right back with the slower riders so I spent the rest of the lap fighting my way through traffic, which cost me even more time but I had fun overtaking both up and downhill. My teammate Jason put in a surprisingly fast first lap and turned up at the changeover point whilst I was just running back from using the facilities (kudos to pitman Ronnie for getting my bike into the right place!) but despite that organisational fail we started working our way back up the table (we were 60th at the end of lap 1).
My lack of XC fitness started telling halfway through my third lap when cramp reared its ugly head (I could have done with a granny ring for once!) so I spent the rest of the race doing pain management (lower back from pedalling sitting down vs cramp from standing and stomping – usually my preferred approach). So that was the bad bits – the mechanical and the nasty pains. The good bits totally overwhelmed them though: This is my local stomping ground, I’m fairly quick on the downhill bits, my tyre choice was pretty effective and I was feeling in the zone. I actually rode some of the downhills substantially faster than at last year’s bone dry Big Dog! And fortunately no-one seemed to have a problem with my shouts of “coming through fast” and much of the time I managed to overtake cleanly. Totally lost the back end through ‘Into The Jungle’, the boggy heavily foliaged bit near the end of the lap, and was reovertaken by a Klein retrobike but that was my only off. Had a satisfying moment when I heard a “leader” shout at the top of A&E (the rutted swoopy descent up near the top of Stanmer) and then didn’t see so-called leader until I was well back onto the fireroad climb. I think that was when I set the fastest Strava time of the day on that segment, there was no way anyone, leader or not, was catching me down there!
So apart from the leg cramp and back spasms hurting a bit, it wasn’t as tough as I was expecting – last year was too hot for me really. And I loved the conditions, there was way more grip on offer than most riders realised, and I know the best line choices so I could really push the limits on the descents. One small bug – I think the chicken run was a lot quicker than the bombhole but I rode the bombhole each time because it’s more fun! By the end of the race we Phoenix Knights (no. 297) had worked our way back up to 28th and it looks like we’d have been just in the top 20 if we hadn’t lost all that time with the puncture and then getting stuck working through traffic, so we’re pretty damned pleased! And after the ignominy of placing much lower than I expected in my first gravity enduro race I realise I’m pretty fast when I know a trail and am not against DH racers and suchlike! I ache rather a lot today…

The whole event seemed to run really smoothly and the marshalls and so on did a great job. The course marking was excellent this year, no moments of confusion on my part. I’ve been to every Big Dog, onederdog in 2009 (my lap took over an hour and I was scared witless much of the time – I’d only just restarted riding MTBs for the first time since the early ’90s and it’s a pretty techy course for an XC race), marshalling and onederdog in 2010, team in 2011, pair in 2012, and I swear it gets better every year.

Saturday ride

Our visitors were great ambassadors for Essex but rode much too fast and skillfully to be polite really…..super ride! This is a generous email to us to thank you all for your efforts.

Great ride, great weather, and great company.
 
Thanks very much from all of us, to you and your fellow Brighton riders for the Saturdays excellent ride. We couldn’t have been looked after and guided better.
 
We would love to visit again may be next year, although a few of us have also started to think about a challenge for next year that you and your fellow riders may be interested in perhaps as a joint effort/event.
 
 We would be happy to welcome you to us. Our local trails are not as extensive as yours, and much smoother and root free, fast rather than technical, hence the slicker tyres and higher pressures most of us sported on Saturday, despite your advice. We will also next year have the 5k Olympic course open and we would be delighted to host a spin around that if you were interested.
 
All the best and again many thanks to all of you.
 
Cheers
 
Mike

if you are not sure…..

Having lived within easy driving distance from North Wales, moving to Shoreham was a worry – I was desperate to find some challenging single track, and trails worthy of regular riding.

I stumbled across Brighton MTB website a few times, and as I was still in need of a good local ride, and some new faces to ride with, I decided to give the informal meet a go.

I have not been disappointed so far; I’ve now ridden with the group on 3 consecutive weeks, each week being entirely different, bringing new challenges, and new faces.

It’s great to be discovering so many great trails at Stanmer park, they’re technical and varied, but no matter what your skill level, everyone involved is always prepared to help out with advice on your riding technique, and will always ride at a pace that suits everyone.

I will definitely be riding with these guys on a regular basis; informal, friendly, and no issues if you’re not up to speed. Definitely worth giving it a go if you’re not sure!

Stanmer’s European Single Speed champion

Chris Noble used to ride with us every week when he lived in Brighton and still returns occasionally to re-hone his Stanmer skills. He was 5th last year in Big Dog so not much honing required really.

http://www.thebicycleacademy.org/2012/04/20/exposure-24-a-race-report/

 He has sponsorship now and writes up his race report at the new link above. Bike magic has a full race report too.
Obviously his success is not just talent, effort and dedication but due to playing in the dark on his bike with us.
Well done Chris from all of us.

Big Dog 2011

This year’s Big Dog entries are already being filled in and places are going fast so to encourage the racer in you here are a few reports from the race last year to give you a feel of the day.

All the photos were taken by Russ Gillespie and if you visit the site you can order the full size canvas to hang on your garage wall. Smaller photographs are also available and he has offered some small sizes for free. http://russgillespie.com/

There is an additional selection of photographs at the end of the report.

If you would like to add your own race report then email me at the usual address info@brightonmtb.org. If I have omitted any report then my apologies and re-send it please.

So this was my first Big Dog and although I hope it will be the first of many, especially if the organisers can bring that weather again. The course was brilliant, but really tough, the first half just seem to be a relentless ascent, although it was worth if for the descents. I would like to say that my ‘local knowledge’ meant that I was able to shred the singletrack but to be honest I had nothing left in the tank so it was a matter of just sending the bike in the right direction. I really did struggle on those hills! Fortunately my partner was an animal and as result we, as a pair came a respectable 31st. Regardless of the pain and cramp it really was a great day and every one, on and off the course were really friendly and helpful, some pretty good prizes up for grabs as well. I could have sworn my name was on that green Decade Virsa, was just my size.

I don’t think I was firing on all cylinders but nonetheless I am determined to smash my time next year and now that my legs have stopped screaming it seems like there is no time like the present to start ‘training’ for next year so I am off out. However I couldn’t help but notice that most of the quick riders (overtaking me like I was standing still) were on hardtails with clipless pedals, so just before I go out I think might have a quick nose around the internet to see what I can buy to make me quicker, besides it has just started raining!!

Thanks to all involved in the organisation and anyone who cheered me on as I looked like I might self combust up the hills.
