I am planning to use a Cervélo R3 with a Burley Nomad trailer for a 20,000 km tour in the US and Canada. My R3 is already set up for long distances but I will need an MTB drivetrain (something like a triple 42/32/24 crank & a 10sp 11-36 cassette) and would prefer to use STI brake/shifters so I can keep my aerobars.
What do you suggest?
I currently have 2 Compact 50/34 10sp 11-28T setups for the R3:
1. DI2 shifters, FD, RD, Rotor Meter & Qrings
2. 105 shifters, FD, RD, FSA crank
If I can save by reusing any of these components in the new setup, it would be great.
Thanks in advance,
