If you are a more extreme sort of bikerider these are a very good set of cranks which should be seriously considered. Buy these cranks now. They are a good british product and soooo honest. They only cost about the same as a set of shimano lx but are about 10 times as strong. GO get 'em.
Initial impressions are they perform well and the guarantee takes care of the durability.
5 stars for the no chainsuck and another 5 for being cheaper than RaceFace. Ridden lots of cranks before which all seem to give up the ghost, no questions asked warranty if you manage to break the crank, what more do you want. People are crazy to buy anything else. So you have to wait, but its worth it. Can't be to bad.
