Hi Everyone,
Thanks for the advice and encouragement.
Time frame will be late July into early August. I don't have a bar bag but do have a trunk bag. My Tri-Cross is from 2004/05, is almost all stock, has suicide brake levers that would probably need to come off if I was going to use a bar bag (= hassle). The bike has a compact double crank. I couldn't give you the numbers without taking a close look. The rear cogset is probably something like a 13-26.
The route is still in the development phase. I will investigate the path and BR5.
Thanks for the packing list Capejohn! That really helps. I tend to overpack and know how I'll pay for that misstep. And thanks for your offer to help. There's an outside chance that I'll need a ride from the Amtrak station to Wellesley on Aug. 4 or 5.
I'll definitely test pack everything and probably test ride the rig too once packed and see what I've set myself up for.
Really appreciate the advice.
Danny
