Shimano gears ... aargh!!

ntl customer · 16-07-2004, 18:13

I decided that I would change the inner tubes today on my bike because they have been punctured for about 6 months now and have never got round to fixing them.

Tyre change went OK, but I've got no idea how to put the bloody back wheel on because of the shimano gears ... I just can't figure out how it goes on! I wish I'd made a note of how it worked before, but as with everything we do from time to time, it's easier said than done.

Can anyone provide me with an idiot's guide as to how to put this on? Or perhaps, a decent res photograph of your bike, or a diagram - anything that'll help me!!

I should have read that fine manual, but as I bought the bike second hand, no manual came with it (assuming such a thing does come with a bike) ...

Thanks

been a while since i did this sort of thing .......... , what exactly have you taken apart ??????????

ntl customer · 16-07-2004, 18:29

I took the back wheel off from the bike itself so that I could take out the old innertubes and replace them with new ones. That I did, but in doing that had to take the chain off the bits at the back but I don't know how to put the whole thing back together again. The geary bit is still on and there is still a chain through it.

God I just wish I had one of those old bikes without all this - much simpler as it just goes round one thing!

That's what I thought, I don't recall taking anything apart for a tyre change. I recall battling with the cog block on a wheel change (which you need a special tool for), but not a tyre change.

If I recall all you need to do is pull the bottom two little coggy things back while you thread the wheel between the forks and chain and back into place.

If you don't pull the bottom two back the chain sort of turns into a single stripe.

I did this a couple of weeks ago!

You need to push the derailieur bit back so that it stretches the chain. Then drop the wheel back in making sure that the end of the axle finds its way inside the loop of the chain.

Hope that makes sense!

bit late now but is this any use to you , no punctures anymore

Right, what you need to do is use the gear shift for the rear gear mech to shift it into the highest gear (smallest sprocket at the rear when the whell is on normally). Loosen the quick release axel on the rear wheel (or the nuts if it's a solid axel). Pull the rear mech gear cage that holds the two jockey wheels (small cogs) up towards the bottom chainstay (the part of the frame that goes from where the pedals rotate to the back wheel) and then using the other hand pull the wheel upwards or move the rear of the bike downwardsso that is slots into the frame. Let go of the rear gears, tighten up the quick release or axel nut and off you go. I can take photos if you still need them!

even with all those spelling mistakes!? Thanks! And bike related questions, send them this way. Mountain Biking is my hobby, also my mode of transport every day. Used to be a BikeHut mechanic, maybe be going back to there soon!

Hope it help anyway, let me know if photos are needed.

good to know, thanks,

my mode of transport, too - although mine is a 'sit up & beg' with hub gears, a springy saddle & a chain guard, so I won't be asking how to make riding a bike more comfortable

mines on foot, can someone tell me how to get these damn boots on

Well, since you're inviting... Those tyres paulyoug666 posted a link for, are they worthwhile? Personally, I can't imagine they are. You may not get any punctures, but I imagine it'll take you twice as long to get where you are going. (Otherwise, we'd all be using them?)
