Another trainer question...
Just picked up one of those Nashbar fluid trainers with the 20% off coupon.
I decided that I'll use the Gunnar as a dedicated trainer bike so I just spent the better part of three hours disassembling, cleaning to a f'n shine, and reassembling my whole drivetrain.
I've never used a trainer before... I know that the preference is a smooth thread tire due to noise concerns, but is the 700x28 tire size ok or should I mount a 700x23? I have a crapload of different sizes just sitting in a box, so it wouldn't be a problem to change it out.
