It’s been around 15 years since I’ve been here last time but now I got back at least a little bit into unicycling and XC in particular. I used to have a 24" Qu-ax back then and now borrowed this uni back from the friend that I sold it to some years ago for trying it out again myself. For this I put the shorter 145mm (or was it 140mm?) cranks from my trials on and that works pretty well even in steep uphills.
Now I’m considering a new own one and since I would like to be a bit faster when cycling with my son (he on his bike) a larger uni could be cool. But because we don’t only go downhills I wonder how much I’d lose in uphill performance with a 27.5 muni? My Qu-ax used to be pretty heavy with its Duro Leopard tyre and some enforcements where things broke or were to weak. How much do I gain with a lightweight uni and especially with a lighter tyre? What’s your experience especially if you use both regularly?
