Not used Avids but have just fitted a set of CR710s and been very impressed with stopping power. Seem significantly better than CR720s, which I have on two other bikes.

Re: cycling in brittany - any recommendations ?

I'm thinking of one of the places we stayed right out on the Western edge - a village called Kersaint. We were actually in a very nice, family run hotel where we were to have a wonderful dinner in the evening and the best croissants we had ever experienced for the following breakfast. I'm trying to...

Re: winter cycling shoes

Coming back to this thread three years later, the weather is turning again and thoughts turn to cold feet and hands. I've been using Shimano winter boots and they have been OK but not quite enough even though, in cold weather I've combined them with merino socks, chemical toe warmers and neoprene ov...

Re: Touring Rims for 8,000 mile tour

How hilly will your route be? Because of the amount of braking, riding in the mountains will use rims at a far faster rate than flat terrain. If you are doing lots of descending, it may be that no rim will give you the life you are looking for. Another thing that can make a difference is the nature ...

Re: Broken Carbon Fibre; hall of horror....

The reasons I chose CF failures to look at (there were/are many steel, Ti and Aluminium ones which I could have posted too) are I guess twofold: 1) CF parts are relatively 'new' in the cycle market, by comparison to other materials, anyway. I wonder whether all the methodologies for design and manu...

Re: Bike crash/Fallen off the back of a car?

This is the technical forum but I'm not sure if you are asking a technical question and don't really provide enough information for technical replies. If you want legal opinions, you might be better posting in a different part of the site. It sounds like the bike has a bent hanger. But may be that t...

Re: bikes on eurostar

My experience (bad) is detailed on a thread on here.

They do take lots of bikes and, if you are happy to dismantle it, it is free. In which case their rules say it must be in a bike bag but, in practice, cardboard boxes are allowed but CTC bags are banned.

Re: Chainline: double and triple chainsets

I've just worked through this again and think I understand it! The double chainset, which takes a 107mm BB, gives a chainline of 43.5mm to the midpoint of the rings The triple, with a 110mm BB, gives a chainline of 45mm to the middle ring, equivalent to 47.5mm to the midpoint of the (outer two) ring...

Re: Chainline: double and triple chainsets

well, I'm certainly missing something! (but in my case, its the ability to absorb information, that I had when I was younger) Spa's chainset and the "Impact" are both really Sugino XD2... trouble is, there's more than one XD2, there's one where you can see 5 arms, and there's one where yo...

Re: Chainline: double and triple chainsets

Providing the granny ring mounts don't foul the chainstay then the answer has to be a shorter BB axle. Or am I missing something? Yes! A shorter (symmetrical) axle would put my chainset in the right place but pull my left crank too far in. The LHS cranks seem to be the same on each chainset (which ...

Re: Chainline: double and triple chainsets

if you want to experiment with crank length cheaply, try spa cycles' triple chainset. Again can be run as a 'compact double'. I don't know how it will offer up vs the stronglight tho. BTW the issue you had may have been because of the difference between an ISO and JIS taper; stronglight make both.....

Re: Chainline: double and triple chainsets

I can see how they made this mistake, both chainsets will have the same chainline. This is measured along the middle ring on a triple and halfway between the rings on a double. So your chainrings will be 3mm further out than they would be on a double. Thanks Meic, I'm sure that's it - at least I un...

Re: Chainline: double and triple chainsets

Having never measured a chainline in my life I feel unqualified to comment. However I'd be happy to join the orderly queue for an unused 165 triple chainset. :wink: Thanks, Gaz! I'll get back to you if it comes to that. The full horror, of course, was that it was just the cranks rather than a chain...

Chainline: double and triple chainsets

This is more me coming to terms with having wasted half an hour on an annoying job I will have to undo then do again. The question is how critical is my chainline being 2-3mm off? It's a 2x10 speed. It's my audax bike so I don't race on it but I do do long rides and use all the gears. Background is ...
