I don't know if you're hanging around the board or not, but you did tell me that you lurk here sometimes so anyways I just wanted to say thanks for your and wife/friends help last weekend at Patapsco. Turns out I didn't need the tube, bu I do appericate it. I was a bit of an off day for me anyways. 2 flats, a bent chain and broken front derailer was the final tally. If you see me out there some time, say howdy and I'll do likewise. If you'd like to hook up for a ride sometime, let me know. Happy trails and thanks again!!
