Tubs

I'm very tempted by a nice lightweight sprint wheelset for the geared bike but don't like the idea of being stranded 60 miles from home (and probably 30 miles from civilisation).
Why would you be stranded? Carry a spare tub and a bottle of sealant, such as Vittoria Pit Stop, and you'll be able to repair or replace and ride home.

@VB - I saw those Edge/Tune wheels on ebay and the price was incredibly low. He probably would have gotten more for them if he'd run it as a straight auction.
