Hot for a Saturday morning at 730 in mid May, went with the Shifters which is the 16 to 18 mph pace. Hung with George the first 19 miles going to the muffin place in Westford. One other guy joined us for a while. After the muffin, I quickly got dropped and waited for three other guys to join me. The did on Powers Road, and then I got dropped on the first hilll on Shaker Lane about a mile later. Everything felt pretty well, I think the seat will be fine. Maybe the current height is good. It is at the lowest height. I have angled the seat front down a little. I positioned the seat a little further back also. I peeled off at Martin Street, but I actually rode an additional four miles to get to Rideout park in West Concord for the start.
