A little over a week ago i was in my backyard practicing my hopping and SPLAT! My entire rim bend. I landed without getting hurt but my uni was ruined. Since then i went to the local bike shop, got a new wheel-set and I’ve been riding fine since then. But i still cannot bring myself to practice hopping again. I’m not scared of falling, that come with the territory of uni riding, but I’m scared of messing up another wheel. Any advice?
The best deals do change with time. All the KH, qu ax, Nimbus, Torker and K1 splined unis are strong. You just need to buy a trials or muni uni with an ISIS splined axle. That is what all the good hoppers do. The K1 is hot now because of it’s current (used to cost more) low price. They used to cost as much as KH does now. Owner reports on the quality of K1 have been good.
I can’t make out the brand of your uni, but it looked pretty cool, all shiny with a taco-ed wheel. I was going to recommend you hang it on the living room wall (art) and get a new one, but that’s still a waste of a good learner uni.
That type of wheel failure usually comes from landing off-center. Wheels are usually very strong for vertical landings, but if you come down with sideways motion as well, or have the uni crooked, most wheels can do that easier than you’d think.
That is a beautiful taco, and guessing by it’s shape I am guessing your rim is a pretty good single walled steel one.
Believe it or not you can probably fix that for very little money. Here is how.
Take the wheel off the frame and back off all the spoke nipples a couple turns. If the rim does not pop back into shape (or close to it) loosen it all the way and see if the rim stays in it’s taco shape. If it won’t go back to round or has any kind of kink it is garbage and you can throw it away.
If it does go mostly back to shape (only smooth wobbles) read Sheldon Brown’s article on wheel building. Hope it doesn’t scare you too much, it’s not as hard as it sounds and that is what you are going to be doing.
If you have broken (or visibly stretched) spokes take out the broken ones and one good one and bring the good one to your local bike shop. They should be able to sell you a few spokes and nips. If you wrecked any nips loosening the wheel (very likely) ask for a few extra and most places will just give them to you.
Replace broken spokes and rounded nipples re-read Sheldon’s guide and re-build the wheel BUT keep the tension relatively low. In some cases a highly tensioned wheel is stronger but this is not the case with a single walled steel rim on a skinny hub. Go too tight and it will “self taco”, tacoing without you even riding it.
Now keep that learner on the ground and hop with something stronger!
A single walled steel rim is pretty much the only kind of rim that can come back from a taco like that, though a double walled aluminum rim would probably still be strait.
That looks just like my first uni, a £40 eBay special. Were the spokes properly tensioned? Mine weren’t, but it’s stood up to quite a bit of abuse since I sorted them out properly.
If you want to hop you will definitely need something sturdier, I would keep that uni for general low-impact riding and get a MUni or trials uni for tricks.
