Re: Chains n' stuff

That depends on the relative cost of your rear cassette/ chain. The last cassette I bought only cost me £8 which was less than the chain but it was on special offer. Incidentally there is an interesting article on Sheldon Brown's web site http://sheldonbrown.com/chains.html , (if you find this sort ...

Re: Chains n' stuff

I have a chain gauge but I get conflicting advice as to what they are actually measuring. Some say stretch some say what they are actually measuring is wear. Either way the chain is definitely longer and more flexible so I guess it is a bit of both. My dilemma with chains and wear is this. Change th...

Re: Chains n' stuff

That is what I was thinking. It is just that looking at the chain it doesn't look as though it is about to give out and it was a very steep bit I was trying to get up but I guess you can't tell just by looking at a chain which link is about to give. As a chain wears the links get thinner and thinner...

Chains n' stuff

Out on my mountain bike today and the chain broke. :( Now the transmission on my MB is worn make no mistake. The chain has more flex in it than a snake and makes a lovely scrunching noise when it does with all the grit it has picked up out on the trails. The rear block has sharks fins for teeth and ...

Re: Matlock CTC - Members wanted

Dear Bazza, Thanks for responding. I was in touch with the Alfreton CTC group and the Derby CTC group earlier this year and was hoping to link in with one or other of them this summer. However my personal circumstances have changed so my plan of starting a "Matlock" chapter has had to go o...

Re: What Tyre for Tandem?

Bruce, thanks for your detailed and informed reply. You are clearly a man who knows his rubber ;). I think we were unlucky with the first Schwalbe tyre that blew up. Technically it was over loaded but only just I am sure any reputable tyre manufacturer builds a comfortable margin of error into the s...

Matlock CTC - Members wanted

Wanted Poster (1).jpg


I am trying to start an informal CTC group based in Matlock, Derbyshire. Meeting for evening and Weekend rides of between 50 - 100Km I would be happy to hear from any CTC member in the area.

Re: Kenilworth Greenway ripped up in the Spectator

I have some sympathy for the writer of this article. I cycle in all three categories (trail, road, and leisure) using variously a Carbon fibre road bike with 23mm tyres, a hybrid, full sus-mountain bike and occasionally a tandem. Sometimes I use the sort of converted railway line /cycle path feature...

Re: Wheel Wobble

I sometimes get a bit of a harmonic wobble when I am going fast down a hill, and find that loosening up a bit and relaxing my arms is enough to get rid of it. I guess having a very flexible thing (human body) attached rigidly to the handlebars only helps reinforce the wobbles, and making the wobble...

Re: Wheel Wobble

There is quite a lot of discussion about similar phenomena at http://forum.ctc.org.uk/viewtopic.php?f=5&t=65802&p=562064&hilit=shimmy#p562064 It could have been just the head wind caused a shimmy. When I was teenager, I had a bike with a tendancy to do that. I was told to grip the top t...

Re: Wheel Wobble

:idea: Well if you really wanted to slow down in a hurry you could try tying it to one's nether regions :oops: but failing that I have a curiously codpiece shaped bag under the seat that could house a conveniently placed drogue shute.

Re: What Tyre for Tandem?

once again thanks to all for contributing. Si - interesting thought deliberately over inflating the tyre isn't going to increase the chance of the tyre bursting is it? One imagines that it would bikes4two - ours was a standard tyre but failed in exactly the way you describe. Thanks for the tip on an...

Wheel Wobble

I noticed a rather alarming wheel wobble while out on a ride yesterday when heading down hill at speeds in excess of 45 kph. I was heading into a stiff head wind at the time at an angle of 45. I ride a fairly standard road bike (Trek 1.2) with standard wheels fitted with Bontrager 23C tyres but have...
