because shimano don't make a suitable product that gives you low gears on a road bike. It is as if they have a corporate blind spot.

In fact things have been getting worse, in that their 'road triple' chainsets used to be able to take a much smaller chainring (even if they came with a 30T attached) but now they don't....

cheers


This is true, but other companies seem to just use a blend of 9 speed road and mtb parts. I shouldve bought one of those, I see no real benefit in having 10 speed over 9, and other bikes were cheaper than my genesis too!

Anyway, thats for another thread.

It's true, but hopefully Shimano will eventually launch a competitor product to the new segment that they're calling "super compact".

In the meantime, as I've done, you have to modify an old 5703, which has a 74 BCD inner allowing sub-30 tooth rings (or other earlier 74 BCD Shimano triples). Other later Shimano triples (Ultegra and Dura Ace) moved to a 94 BCD inner, where 30T is the smallest ring available, as you allude to.
