I built up a Solaris on 27.5+ and having a 29er already figured I would experiment with the wider wheels.
Went for a Nobby Nic 3.0 on the front. Trailblazer on the back.
Have done 700 miles on it, since March. in sticky clay mud, it was a ballache.
in moderate mud, I was quicker than on other bikes. Up and down.
Dry and dusty….wow. I am wondering whether I need a full susser at all. It’s not far off the mile munching speed of a 29er on anything other than tarmac, and it’s not too lacking on the way down in comparison with my full suss. I keep reaching for it rather than my other bikes. Some of that may be new bike syndrome…but have been pretty impressed.
Tyre pressures. Definitely more critical. Too high and you don’t get the benefits. Too low and on any high speed corner it feels like you’re going to tear the tyre off the rim.
I live in the south east and find it an absolute weapon for the south downs and Surrey Hills.
Went to Fort William and hired a 6Fatty. Also impressed with that to the point I was considering buying one!
That said…I want to put a full winter on the Solaris before waxing lyrical about the tyres. I think that a set of standard 29 wheels would be a better bet for a typical wet british affair.
*and no punctures at all in 700miles.
