That Montebello climb makes the what I considered to be the arduous climb up Page Mill to Altamont look like but a wee pimple.
This is a great add-on to the M ride.
I'm going to do this add-on whenever I have time. Perfect endurance MTB training to try to find the legs after going full gas for an hour on the TMR.
Ouch. I like it like that.
Thanks, Jamie! got the wheels....
