Easy question:
Are TA Cyclotouriste chainwheels the same bolt pattern
as Stronglight 49 ? Will the TA triple bolts work on the 49 ?Harder question for advanced students:
On Sheldon's site, it says that you want to do a half step plus
granny" setup with this TA crank. It infers (if I'm reading it right)
that it will be difficult to shift the small to medium wheel if the
medium is not close in size to the large (outer) chainwheel.http://sheldonbrown.com/harris/french-cranks.html#cyclotouriste
I'm having trouble grasping this, or I'm just reading it wrong.
Why would the medium to large size chainwheel relationship
impact the small to medium shift ? I would think that you'd want
the medium closer to the middle of the range for the smoothest
shifting from the small to medium.
if the medium is much smaller than the outer, the chain rubbing on the
outer ring will limit the bend the chain can make during the 1-2 shift.
It might catch on the outer instead of the middle ring
