I just switched to disc specific rims with a deep "V" profile. This leaves little room to get a pump on the valve. Anyone know what are the lightest mountain tubes with longer than average 48 or 60 mm presta valves? (I already checked out the weight list but it does not specify valve length on most tubes)
Thanks!
