Well varies, but in Canary Wharf everyone has money coming out of their arses so its usually a case of 'this is what I want, I don't care how much it costs'.
My CNC backens made an annoying clunk as they returned into the slave. They were on heatsink reds which, it appeared, are useless pads. Didn't think they felt overly stiffer, but if i look at my plastic backens on my Cousts they do flex a little.
Worked in Evans Cycles Canary Wharf during last summer and christmas, and will be again this summer. Means I can earn money to spend over the year at uni, but not have to miss out on uni stuff. Got about £45 a day, can be pretty easy work.
I wouldn't really wanna use that, how old is the chain? If its over like 5 months old, I'd replace the whole chain, if not just replace the broken ones and keep an eye on the others.
