More and more this set-up is making sense to me. I have a pair of VO
50.4 BCD cranks on my rando bike and while I love the 46/30 rings I
just don't like the cranks. Set-up is a bit tricky as it's much easier
to have issues with chainline and the crank arms hitting the chain due
to the design. Why they didn't update the design a bit, like Rene
Herse did, rather than just make a straight copy of the TA crank is
beyond me. Also, I don't know that I'm a van of the super low q-
factor.
I sold my QB a while back but kept the cranks. I may use them on my
Hilsen with an 8-spd 11-32 cassette. Two questions:
1) What derailer do I use? Double? Triple?
2) Are there any issues I need to be aware of when using the big
(middle) ring and the lowest or highest gear?
I guess I have a third question, how do I determine chain length, just
wrap the chain around the big (middle) ring and lowest gear?
Thanks!
