I've got a pro-racer (or I thought it was) so has Hooga75, we noticed today that the frame sizes are different. does anyone know the different geometries of the hutch range (Pro Racer, Raider,Pro Star, Expert etc)?

thanks

Jim

Gonna go out with the tape measure!  :daumenhoch:

Right, I've been out with the tape measure and here are the sizes, can't measure the angles of seat post and headtube though.

TT = 19"
TT outer diam = 1"
Downtube outer diam 1 3/4"
BB Height = 11 1/4"
Chainstay length = 14 1/2"
Wheelbase 35 3/8"

Which means it could be either a Pro Racer or a Hollywood. It has the wheelbase of the Hollywood but the rear seat stays aren't welded below the TT like the Hollywood. It also has no serial number and i think the hollywoods had serial numbers as they were later. The other thing is that it has holes drilled inthe forks which the Pro Racer didn't. They may be forks added later.

I'm all confused, but it does seem to be a Pro Racer.

Anyone shed any light?
