Re: How much difference does tyre width make.

R2. Not talking of roll-down tests. Not talking of energy expended uphill or downdale. I'm saying that I remain to be convinced due to my experiences with others freewheeling down long gentle hills. Maybe 15-20mph on the tops relaxed and chatting side by side freewheeling. . It depends on the gradi...

Re: Chain Links And Tool

I have a Topeak Mini 18.

The Chain Tool seems plenty strong enough when I've used it on 10-speed chains

Re: Which brand? Apollo, Indi, Challenge..

£150 is a bit cheap for a reliable new bike.

The Decathlon one looks ok from the pictures, but the text is different so not sure what the spec is

For £150 however you can buy a better used bike.

Re: RTW cyclist fined £75 for cycling through Bedford town centre during prohibited hours

Today we learn that Peterborough, Bedford, Hillingdon and Waltham Forest - all using private mercenaries - are responsible for 60% of the PSPO fines in England & Wales.

Re: Simple guide to worn rear cassette

8. Because the price of the socket and the price of the chain are similar. 9. And it therefore isn't worth the price of the chain to save the sprocket. 10. Especially when you've pushed both to their limits. :mrgreen: Depends on your wear rate, and ratio of chain price to cassette. Decathlon prices...

Re: Kilogram per gear inch or tooth

I'm very happy to admit that I could save a bit of weight (I'm 75 kg at 5'10") and I could certainly up my fitness (although I see few* other 65 year olds on fully loaded bikes on the hills around here). The point though is taken: it is a good place to start and I actually do notice the differ...

Re: Kilogram per gear inch or tooth

But surely that's not true? If I need to lose 9kg in order to up the gear from 28 to 30 teeth, that means that I could carry 9 kg more if I lowered the gearing by 2 teeth! So lowering the gears is actually very effective while losing weight isn't. BTW, I am assuming that changing the gears will aff...

Re: Kilogram per gear inch or tooth

It shouldn't take too long to work out that even getting a 10% total weight reduction is unlikely to be quick or easy, and thus using weight reduction as a means to easier riding up hills is certainly worth thinking about but is unlikely to provide a complete solution by itself. cheers A digression...

Re: Kilogram per gear inch or tooth

The 18kg is only relevant in the context of the system weight I.e if you weigh 60kg, then losing 1kg is more significant than if you weigh 90kg At any rate the correct procedure is to add up the total weight of bike, luggage, rider and other stuff being carried then treat each 1kg as a percentage of...

Re: Simple guide to worn rear cassette

Not sure there is one - I this week changed two chains. One is on my wife's bike and gets little force through it, though regular use. Replaced chain, all good. (3x8 mtb hybrid drivetrain) Second was on my son's bike with road gearing, he is pretty strong and as soon as the chain was changed it was ...

Re: Mamil bikes

This thread will go well... Maybe the CTC can come with some "Not Approved for CTC use" stickers we can put on such bikes ? Ah well I think this depends . In my local CTC chapter there are loosely four, but for practical purposes three groups each going a bit faster than the last. In the ...

Re: P******e fairy adieu?

Well a racing tyre is around 300g. A super light tube is around 55 grams. The air weighs very little.

There are plenty of puncture resistant tyres that weigh less than this system. Presumably the appeal is more that you don't have to inflate it.

Re: Park Chain Cyclone Cleaner

it certainly looks easy, but there are some issues: * the little wheels come out and have to be reseated * the wheels get full of gunk which needs to be cleaned out * the sponge thing needs to be squeezed out because it retains soapy water * the liquid can come out quite easily, so if it's not kept ...
