WB Bicycle Gallery: Robert Clark's Koga Miyata WTR
A 2004 Koga-Miyata 'World Tour Rohloff', a world tour bike out of the box.
you can pick one up, new, using Koga's signature program's built-to-order from menu plan.
My Ice-winter bike was developed from an old 'stumpjumper sport' frame..
acquired with a broken dropout, and no fork.. A mechanic not a list maker, I Got it fixed Up.
If you swap out the suspension fork to a rigid suspension corrected one or just get an older MTB
with a rigid fork that was not yet altered by design, for the Suspension fork travel length in the first place.
It will work ..
