Spokes and new cassette arrived today so I’ve built up the rear wheel and renewed the drivetrain this evening. There’s ample room for the Horizons and guards both front and back, with 5mm clearance to the chainstays either side (the tightest place for clearance). Loads of room around seatstays and both bridges, even with guards, which I struggled to get 700x32c in without rubbing on the bolt going into the chainstay bridge through the guard.
Haven’t test ridden yet because the new chain isn’t playing ball with the really knackered old chainring, gonna have to wait a few more days for the new one to arrive. As an aside, I’m very happy with the Sunrace 11-40t 9 speed cassette for the price, with a 40t ring it should give a fairly decent range.
Ditching the rack and getting some dropbars sorted soon too. Could do with wider guards as they barely cover the wider tyres. Hopefully the photos work!
