Having made a winter MTB a some years ago (rigid 26″ ss on 32-17 with ‘alt’ bars and 1.8 mud tyres) I liked the benfits of less faff, expense and rediscovered the buzz of simple bikes that I had as a teen.
I played around with alfine hubs on MTBs when they came out, quite liked them. To be blunt, I think conventional gears are unsuited to long distance winter use, I’ve limped home on gears that suck, skip and won’t engage properly too many times. 12 – 16ish tooth cogs are pretty hopeless in muddy conditions. And exposed suspension elements always bother me, they’re pretty good these days but it’s still a harsh test of expensive kit.
Now, my winter MTB = my summer MTB.
If it works in winter clag, it’s good for the summer high-mileage use with a change of tyres and maybe gearing. Rigid 29er SS, blocky 2.2s in winter, big 2.4s in summer, sometimes an extra tooth at the back to help get up boggy climbs with less momentum. If I want some gears, I’ve found a cut-cassette 17-34T limits chain line change and ditches the tighter-wrap gears so works well in the mud too.
All I want now is a 5-spd wide-range Rohloff. Lighter and a bit less ‘grinder’ feel, it’d be perfect.
