Put the GP 4S tyres on. Tweaked the brakes. still gutted that these michelin tyres punctured so easily.

I will repair the hole in the tyre with some E6000 rubber glue i bought but i dont think I'll be using the tyres for anything else...

I downloaded the free OSM map of Great Britain and put that on a Micro SD card for the recently fettled Garmin ... It isn't Ordnance Survey standard but I already have the OS 1:25,000 and 1:50,000 maps for the UK on my phone and I was not going to pay again for the Garmin version. It will do for navigation purposes on rides. If I want to look at the OS map, I can stop and get my phone out!

Putting new winter bike together. Why did Shimano change the diameter of their Hollowtech bottom bracket cups? Ok, it came with an adapter, but my BB tool is a nice solid cup type, and the adapter only fits the open type ...... doh. And why was I certain that my 31.8 Front derailleur braze-on adapter clamp would fit the new frame - which actually requires a 34.9? :banghead:

Following on from a discussion with @Globalti in THIS THREAD, last night I decided to give the brake pads in my disc braked GT Grade some attention. Small chamfers to both leading and trailing edge of the pads and a general rub up of the friction face to remove any possible glaze. Of course this mornings ride was bone dry and crisp so no squeal anyway but I am sure it won't be long until I find out if this has worked.....

Also took the opportunity to do something that was mentioned to me by a fellow Grade owner some time ago. I checked the chainring bolts of my 105 crankset. These are a rather special affair that are just a torx bolt (why Torx?) screwing into the back of a presumably cast outer chainring. A rather elegant solution IMO but the chainring shape spoils it for me because it looks a little ungainly and not at all as aesthetically pleasing as it should. Anyway, the bolts were not loose, but neither were they tight and easily nipped up another quarter turn, so definitely worth doing before disaster struck. Thanks to @Kestevan for the warning :okay:

This mornings school run with Skol Jnr threw up another issue. Right from the start my chain was making a regular noise every few pedal revolutions. A short distance into the trip I stopped to investigate because it seemed to be getting worse. This is what I found....

As this is the only 11s bike in the fleet and only a recent addition I haven't yet got any spare chains or links for this so the bike may be unusable until this is sorted. I do have a link for a 10s chain but the Vernier callipers tell me this is a full 0.5mm wider so unlikely to run smoothly.

EDIT: the puzzling thing about this is that the link has broken on the inner plate. No surprise there as that is the side that has to climb the sprockets when changing gear at the back, but the chain travels to the right in this picture meaning the part of the plate where it is stamped KMC is the bit that should be taking all the hits during a gear change?

The ramps on the inner edge of the chainrings assist

I completed the school run very gingerly and remained seated just in case! :eek:

The other puzzling thing is that the bike seemed fine when I put it away after a hilly 15 miler on Wed night but was clearly not right the moment I set off today. I think the gremlins are sabotaging my bike while it is hung on the wall. A spoke snapped in the rear wheel under similar circumstances just before Christmas, was fine when put away but twanging like an out of tune piano the moment I set off on the next ride?

Wow! Impressive picture and interesting that the chain didn't snap fully. I always carry a spare joining link in my small saddlebag. Actually I've got a handful of 10 speed links that I don't now need, if anybody wants them.

That disaster DID strike on my one forum mountain bike ride - DETAILS.

I have loads of spare used 9spd links as that is/was the majority of the fleet until I bought my oldest lad and Mrs Skol 10spd MTBs. Thought I had better get a spare link for them so picked up a 10spd chain for the spares bin. Not used this yet but now need to get something 11spd as well! I have just emailed Wiggle, the bike supplier, to ask if this will be considered as warranty. I am not going to be upset if they say no because I know chains are a funny one, but thought it worth asking the question.....

As im still running a 10 speed I'll take a few if you dont need them. Price of postage? :tongue:
