This does not answer the question directly but I use a less expensive alternative: Electra Ticino (made by FSA) w/ Velo Orange 46/30 rings. On my AHH, I am using a 110mm bottom bracket. I don't know how the Compass cranks are shaped but the Electra allow you to use almost any front derailleur, as the arms are shaped and do not interfere with the front derailleur.
I did the PA Rando 200k back in October (lots of hills) and the combo with a 10 speed rear (11-32), Dura Ace downtube shifters and everything was fine. http://i91.photobucket.com/albums/k292/bylar13/F1C8A797-C1B3-47AB-83F0-CB6413B8FBA6_zps4woollr7.jpg -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
