Started stripping my ultegra off my upright it's all new, cam off easy went on the silvio easy. Have the frame together just a few things to do and it is finished. Need to file down my derailleur hanger, add my chain, secure upper seat holders to head rest and then adjust the bike to fit me. Picking up my cables Saturday for install. Most bike shops not to interested in helping me with my first bike build in like 20 years. So I find a tandem dealer within 10 miles he said he would help me, he has never seen a silvio so he is excited about seeing it. The bike is awesome looking and when I sit on it it feels natural. Cannot wait to ride it Sunday if it is completes other wise will have to wait till I return from and business trip.
