Its xl 60cm. The tyres are 40c nanos. They measure up at 41mm.
The xc pro is just some bits from the shed, the levers dont actually have the correct barrel adjusters...
The shifter was built out of my xc pro shifter spares box...over the years ive gained loads of them as scrap. I normally get the bodies, clamps and tops cerakoted then rebuild the guts from bits of others.
Great shifters and genuinely do 8 speed (they switch between 7 and 8 which is a great help. Plus suntours spacing was more akin to shimano 8 speed for both 7 and 8...so oddly they do 8 speed shimano, better than 7!
