old tyres

Old tyres seem to have shrunk over the years or maybe I have forgotten how tightly fitted they were to the rims. After a short fight with bending tyre levers the tyre eventually conceded. The old sealant (Stan’s) had disappeared over the years but left a small oily residue and an additional rubber coating over the tyre and the rim insert which I have tried cleaning with white spirit but it is slow and leaves a film behind. Instead I will try and find some old stock Stan’s rim tape with valve however the Joe’s No Flats alternative would do if needed.

The main problem I have in the re-commissioning is the space is not really set up for access and mainly used for storage so I have a bit of a task in reorganising everything as I have fitted a quart into a pint pot. I have the bike stand, more than a few tools and essential spares going back to 2002. Yes honestly 2002. I may have to reduce this substantially but I am guessing much of it is no longer used on a modern 3d printed electric mtb however my concern is the availability of spares going forward for my old frames.

I still have the frame from the 2002 Specialized mentioned in an old post somewhere on the site here as the last bike I will ever need however six frames later that could be destined to remain as wall art. I would like to just list and buy all the parts I need in one delivery but the lack of CRC means I have to hunt around and cross check details like the size of the Mavic rims (27mm it seems) in order to order the correct stuff.

This make take a while….

Bike work

I need to start with some sort of plan but unfortunately it might be that some parts may be difficult to find. There is a problem with the tyres so I will remove the sealant and attempt to reseal with old sealant, it should last ten years right?

Following that I will look at the transmission which does not seem worn but something is not right. Brakes seem to work but maybe a re-bleed would be a good idea so I don’t discover hygroscopic problems on the first downhill section as there will obviously be a gate lying in wait. I am unsure if the fork will work but if the seals have not dried out I could drain and refill as a trial. If necessary I could replace with an upgraded model if the sizes are still available for steering and wheels but I will wait and see if this fork still works.

Wheel bearings will need checked after sitting so long and the bottom bracket might need more than a look and a bit of hope.

So that sounds like a start for now but I am sure I will find a few things along the way.

Changes

I am intending to resurrect this site if I can return to the saddle but first I need to carry out some bike maintenance which I may share here if I can remember how to fix things.

Winter Thursday

Last week’s ride was not typical. Carl and I were early and headed out to check the trails before the ride at 7pm. This bit was typical. I had set up ready for a cold, frosty ride with lots of layers and a fat tyre on the front but it seemed slightly mild.WP_20160123_001

Going, going, gone

After many years and many thousands of miles my Mojo will visit Stanmer no more. It has died from internal injuries probably due to old age so it is time to be put down like a faithful hound or aged grandmother perhaps. Many hills, many trails, slightly less jumps perhaps but in all seasons and it has coped pretty well.

It can be a little flexible but a Lopes link improved this considerably and improved shock bushes kept it smoother for longer. Local chalk and clay does kill bearings so they have needed frequent replacement but quite a simple job to do this. Integrated headset was fine and needed just bearings when winter grime had leached inside and started tinworm on the ball bearing surfaces. Bottom bracket eventually struggled to cope with many changes of bottom bracket furniture but this was needed due to the high mileage and the poor conditions rather than any weakness or design fault.

Paintwork has been robust and solid but protective tape, lots of washing and little touch ups from the supplied pot have kept up appearances. Seatpost insert has been solid and outlasted a Joplin dropper post and is not creaky or a poor fit however it likes a little pot of magic carbon grease and lots of winter wiping.

It is a little old school in its’ geometry but it climbs well, traction is excellent, front wheel sits and steers on the ups and downwards it takes bumps well, it does not fall through the suspension travel if set correctly and has a light touch over the bumpy stuff. It jumps fine but squirms a little unless it lands dead straight and although the head angle seemed slack when new current figures make it seem steeper now.

As an all round bike it has coped with anything local and national but I never threw it off an Alp and it has not needed to suffer many jumps to flat at low speed but it has managed a couple of races, been lead bike in the dark a few thousand times, managed dozens of long distance rides with aplomb and been through and over most of the local flora and occasional fauna.

It was very expensive and only the longevity has justified spending the same on a bike as you could on a car so the law of diminishing returns establishes itself once more. The extra cost gets you newer, lighter, stronger and great quality but it is not twice as good as something half the price but it is a bit better. Everything is made to size and replacement bits fit nicely. Tolerances are tight but this a good thing allowing the bike to feel a bit tighter than you expect on rough stuff.

As an early adopter of the carbon frame the early question was always strength, especially on impact, however the ibis has been grounded over obstacles, had flint chunks fired at it, been dropped more times than I would like to admit and the frame has shrugged it all off. Keeping any frame for years and years and in use rather than hanging forlorn on the garage wall is not a common thing but better, lighter frames are not that common even if price is not a factor. The suspension using the DW link is super for pedalling and better than my previous Nomad or Marin suspension systems in most situations that I usually ride.

As it has had a long, hard life I expect the wear and tear marks are commensurate for this but if you were considering any second hand frame, especially carbon there are a few detailed photographs to aid your inspection.

IMG_3974This is the insert for the lower link and is is loose inside the frame. I have heard of this in frames of other makes so checking really carefully is required in order to notice the slight initial movement of an assembled bike. Under no shock force and link removed it wobbles with your fingers.

IMG_3975Upper link point is fine despite a million movements so carbon itself does not wear out if there are no friction surfaces.

Bottom of the rear triangle which is the lowest bit of the bike and which bottoms over logs and rocks. Super solid, seemingly very, very thick and not covered with dings and dents – part of the price paid here.

IMG_3979Running a fatter tyre in wrong conditions caused a little wear when the mud built up however prudent tyre sizes avoided a repeat of this and this was years ago so no time based fatigue of the carbon matrix

 

 

So great bike for me and a difficult problem in choosing a replacement with the obvious criteria of colour paramount. Thursday nights in the dark just don’t seem right without an orange flash somewhere in the trees.

Tuesday’s ride – painful with a difference.

WP_20131123_006 It started off as a regular Tuesday ride with Tom’s warning of gales and mud reducing the field to half the regular size. With Ash in puncture land somewhere on the SDW Tom re-jigged a route to allow a rendez-vous and avoid a headwind or the remnants of the travellers and their detritus. So tarmac, orchard, hill that hurts, horseshoe and another hill that hurts. Definitely not a Thursday ride but not getting dropped and not everyone else found the pace easy.  Finding Ash we turned with the wind and rode the ridgeline. Continue reading
