The Vivente thread has put the wind up me some what in relation to the standard ratios and sore knees at the end of the day?
I suspect now is the time if changes need to be made

Cheers Rog

Sheldons site is a great sorce of information on all things bicycle.
I pick the bike up tomorrowso I suspect I'll get more of an insight as to what will be required very soon.
What are you riding and what weights are you pulling at 16.7 gear inches![]()
My Epic at 22/34 produces a ratio of .65. I'm pretty sure that this is not as low as 16.7(and I can climb a cliff at 22/34)
Thanks again and I will check out the derailleur/chain length issue.
Cheers Rog

I got the smallest ring that would fit my FC7701 cranks which I think was a 39T.

39x36t with 20" x1.5" tyres would yield 21.1 gearinches. Not really low enough for semi-trailer drivers in my book.![]()
