Triple to compact

markwb79

sorry I didnt use the search....

What needs changing to go from Ultegra triple to a compact?

Just the crank, or levers too?

Bottom bracket as well (shorter shaft)
Think shifters are OK since self limiting, but dont quote me on that

If it's a Hollowtech 2 type crank then the BB is the same; the spindle is integral to the drive side crank / spider.

Crankset, front mech, and possibly the left hand shifter.

Shifters are fine.
You should set it up so that the big ring up shift moves to the big ring. Middle position goes to the inner ring.
The low limit screw on inner ring stops the chain going inwards when you inevitably accidently release down to what would be the granny ring and you'll be safely releasing cable tension if you move to the unused granny ring shift position.

If you set it up so that the big ring shift position is unused, you'll find yourself trying to snap the cable if you accidently shift to the unused gear.

This is the 3rd thread I've offered that advice to in the last week. Is is triple dumping season?

Now l'etape is over, maybe you are right!

If you know of anyone wanting to go the other way. sure some sort of swap might be possible
