Either way, I'd take the chance on it. Appreciate and agree that Ant should have first call. PM me if he declines as I'll take a punt. I fitted a perfect six on the rear wheel I built but the clearance looks too tight, 123mm hub OLD as measured. I really like Suntour kit, it's always been sound on all my road bikes. GIGFY did warn me that the Perfect6 wouldn't work but I'd already bought it anyway. It's been a hold-up with the Wester Ross, along with indecision & prevarication... etc! Either way, thanks for the offer, appreciated ATB.
