As jemima says,the ndiza is awesome fun.bought mine last year ,def burly, and even lightish (30lb) occasionally think of selling on to fund new toy,then another ride in the woods and i just cant let it go.! seems to run on pure neglect with bearings still solid and smooth (all mates on vpp etc replacing bearings left ,right,centre). did a 5hr slog couple of weeks ago. over grinton, gunnerside etc, single ring and loved it. honks up climbs like a roadbike, scalectrix on the way down…(mind you i,d poss swop for intense ss and live with the bearing issues, lol…)
