I’m looking at getting a tire more suitable for trail riding on my Nimbus 24. I bought the unicycle used so I’m not sure what model it is but by appearance it looks to be identical to the 24 inch Nimbus II listed on UDC only with a Kenda K-Rad 24x2.3 tire.
So the question is, would a Duro Wildlife Leopard work? The frame measures 75mm wide with about another 75mm clearance between rim and crown or around 30mm from the top of the current tire to the crown and the rim is 32mm wide.
If the Duro won’t work does anyone have any other suggestions for a reasonably fat 24 inch tire that is still readily available?
It seems like 24 inch off road tires are getting pretty hard to find. I’m searching for a 24x2.5 and in germany the only one that seems readily available is the Maxxis High Roller 24x2.5. As lightbulbjim has pointed out, it sounds like it could be a bit too tall but really hard to tell without having one in hand. Anyone know how tall this tire is from the rim? I have a bout 3 inches to work with. And will this tire likely work ok with a 32 mm rim?
I’ve read that a 2.6" tire is the max tire that’ll fit under the crown on the Nimbus II. I saw a pic & the clearance was REALLY tight. I’m sure the tire would rub if got just a tad out of round. I had that exact issue on my 26" Torker LX. Max size 2.5" knobby & I had to shim the bearing caps by a couple of mm.
I have an older 24" Koxx muni with the Duro and although I have enough lateral clearance, I had to use shims to add more vertical clearance as even with the slightest bit of mud it would scrape to bottom of the crown.
I can’t today, as I’m sick in bed, but some day I could measure the width of my Duro. Not sure, but I think my rim is probably around 35-40mm.
From my memory with mountain bikes, I think the width of the Maxxis High Roller 24x2.5 runs lower than the given value (a 2.4" Schwalbe is usually wider than a 2.5" Maxxis). So that might be a good option, but you will probably have to add a vertical shim. I’m not sure what the max vertical is that can safely be added via shims? Off hand, I’d guess that more than 5mm is probably too much.
Well I went ahead and ordered a Maxxis highroller 24x2.5 so will just have to see how it works when it gets here. I’m hoping I don’t have to resort to shims but just in case, does anyone have more information on how that would work? I’m having a hard time picturing how I would use a shim to increase my tire clearance. I’ve tried searching but haven’t really come up with anything that seems relevant.
hmm. didn’t find anything with pictures and only really old posts. I think it only works with older style bearing cup holders (not the CNC milled like the new aluminum frames). Looks like people have used coke cans, rubber or aluminum shims. I honestly can’t remeber which I used as I did it about 6 years ago and haven’t had the wheel off now in at least 3… I’m thinking I probably used rubber strips, but maybe aluminum.
My extended bearing caps were for fitting what was essentially a 31" wheel in a 26" frame before my custom Triton arrived. It worked as a temporary test setup but I would not want to ride like that long term.
Muniham might need mm, not inches. A simple shim should work.
Nice! Tons of clearance! Once you get a little experience, would love to ride, as I usually ride by myself.
I try to ride twice a week, weather permitting, usually Wednesday morning and Saturday/Sunday morning on the Isar, south of the Munich Zoo for about 3 hours. Most likely Wednesday doesn’t work for you, but maybe a Saturday/Sunday some time (we are presently in South Tyrol till after Easter - brought 2 unicycles so hopefully will be warm enough to do some muni). But maybe in the spring or summer.
