You can easily stretch out the rear. I did it on mine. Its amazing how much steel will take. A length if threaded rod with 2 large washers and nuts. Gently wind out the rear end. Keep releasing and checking measurement. Avoid stressing the gear hanger and finally check wheel alignment.
That's absolutely brilliant drystonepaul!
My first MTB was the DB Ascent EX you have there. The Holdsworth too, with the 42:16 is very encouraging, because I'm using a 43:17 set up.
I've kept the moving parts to 1/8 specific with an Izumi track chain, Halo Fat Foot and Velo Solo front ring.

I am converting 1996 Peugeot hybrid to a single speed. The specs are:
700c wheels
MAVIC cassette with Halo Fat Foot sprocket 17t
68mm bb shell
Campagnolo Chorus Cranks (172.5) with 43t ring on the outside.

Excellent. I bought a Roy Thame 4 years ago. He built the Holdsworth team bikes.
My frame set turned out to be a special order tube set for Ciöcc cycles. When Ciöcc got sold on Giovanni Pelizzoli, the founder, passed on some of the tube sets to Roy Thame.
Research is half the fun of a build.
I've ordered a ZTTO tensioner to try out. The half link method sounds good except I'll be running an Izumi 'jet black' chain which has gold pins. Where would I get a march for that 1/2"?
Ive had ZTTO bits before. Made somewhere in China, but the CNC work looks good. Can't get any other colour...
