Getting ready to list my carbon fiber Woundup Tandem Duo fork on eBay this evening unless anyone here speaks up first. Bike has never even fallen over with this fork on it, let alone been down! ;-)
The fork has the full carbon crown as pictured on the "Duo" page with the bright-band canti studs as pictured on the regular tandem fork page. The carbon steerer is 9 7/8", or 252mm long, and would probably be fine for a bike up to 62cm or more. On my 58cm Trek I used a full two inches of spacers, allowing me to adjust the stem up or down.
I may be wrong, but I figure it ought to be worth around $400, so if anyone here wants it for that, I'll take care of shipping and insurance.
