I just rebuilt this trailer not thinking of you racer guys at all, it's a little small, though it will fit one bike nicely.
It's around 38" wide and 8' long, Steel frame and deck, new springs, lights, and wiring. Tires have tons of tread. It is built fairly heavy but doesn't weigh too much, no problem for a car.
I thought it would be good for the yard clippings and such, you know Saturday to the dump, but the sides will come off pretty easily and I think 2 bikes will fit on the deck with a little coaxing. Maybe its a good starting point??
If your interested, give me a PM.
Looking for $450.00
