Whether they’ve got enough torque depends on your level of skill and how steep the terrain you’re riding.
If you’re comfortable on your 29er and you’re riding on reasonably level ground with a decent quality surface then you should definitely find that the torque level is reasonable. You should still be careful though, because changing crank lengths can cause you to UPD more (and in interesting ways) - at 29er speeds, this is worth bearing in mind.
If you were doing offroad or lots of really steep stuff, you probably wouldn’t want to go that short (again, depending on personal preference).
I rode my 29er with 90mm cranks for a short while but found it uncomfortable to have cranks that short, although it did give me better sprinting speeds. I’m currently on 127mm cranks, which I find are good for going moderately fast on road or off.
I dont think it will be that bad, if you just use it for riding places it will allow you to cruise at a higher speed, which will be good. I have 125’s on mine now, and i like them, but I have ordered in some 114ml’s and will post up how they feel when i get them.
I think the results may depend substantially on your choice of tyre (and yes, intended usage!)…
Last year I was doing a lot of road riding on a 29er with a 2.35" Big Apple tyre. I started with 127s, changed to 114s and found this a big improvement - essentially no loss in control, but easier to spin, only downside was it wasn’t quite as good off-road, but probably better overall / as an all-rounder. I then had to change to 102s (I bent a 114 in a silly accident involving catching the QR handle of the seatpost clamp in my shorts…!!!), and…well, possibly better as a long-distance (40mpd) road machine, indeed I hit some fairly decent speeds, but substantially harder to control, couldn’t idle (had to hop at traffic lights), and couldn’t handle anything more than verylight* off-road, preferably gently downhill.
This year, tho, after a long time riding a 26, I’m using a Nimbus 29er XC with 29*1.95 Kenda Klaw tyre. This weighs approx 700g to the Big Apple’s 950-1000g, and with 102s again, the difference is enormous. I guess it probably doesn’t hold it’s speed quite as well in some situations, but on the whole it’s enormously better: much more manageable/controllable, much more manoeuverable, can get up to speed much more quickly (i.e. acceleration/deceleration), idling not a problem, surprisingly capable off-road (nothing very heavy, but canal towpaths, mud, many poorly-surfaced “bike paths”, trials, etc. etc.). I suspect that whereas 114s seemed “the right length” for the Big Apple, 102s are “the right length” [for me] for the Klaw as an all-rounder, and as such it’s a much better uni; however, the effect of the change in tyre is such that I’m even tempted to try 90mm cranks - for more speed on-road, even if I doubt that’ll be as good all-round…
No-I couldnt make it out to OUI But wish I could have though!
But I must know you-as we do go to the same unicycle club lol
I ride a KH 20-I have been going out to the club on thursdays mostly-but after the Christmas break I will be going out monday and thursdays
