anyone else find they more frequent than on 26 or 27 bikes , or it my riding style ?
Do you have a massive arse?
That could be the problem.
Or do you shove it in the way of the wheel?
Is your bike too small?

Talk like that is not acceptable on here.
maybe it was the arse job i had , thanks guys for ur worthless replies ! 🙂
why that not acceptable , is this a nancy fancy forum ?

Me too, terrible choice now I look back on it. Although falling off is less of a pain. In the arse.
Your arse is on strike because you ride a 29er?

Whats one of those?

Yes, mostly.
Yes, I had this issue. Main issue being my poor technique and the bike being too short for me! It was this amongst some other issues with 29ers that made me switch back to 650b
No problem with cling-ons though?
one of my 26" bikes I had this a lot, one I didn't, one some of the time. I didn't on the 29r but that was an XC bike, I do on the 650 but that is only when it gets real steep.

Basically only mid screw-up. It's just not that often that your bum's got any place being there, these days, the shape of modern bikes + dropper posts put paid to that.
I've buzzed my bum on both my old Solaris and my Whyte T129 a couple of times. I think it's part technique and part clash of dimensions!
Only happens on certain techy drops to be honest, not enough of an issue to warrant a change of bike.
Surely dropper posts are what allow the arse strikes?
Well, it's not just the wheels I guess, it'll be the combination of bigger wheels and a larger BB drop

Not really before then we used QR clamps.
I still remember the day I burnt my ball sack when it got trapped between my wheel and (26") frame...

Not really, used to be people were obsessed with getting behind the saddle, now you can get low while still being in a good position above the bike.

Try getting your weight low with a flattish back and shoulders over the bars instead of hanging off the back in a defensive upright position.
Tbh, If you're hanging that far back, you're not really in control of the bike, unless your bike has a ridiculously short cockpit, or you have arms like Theresa May.
last 3 comments applied to me in my early days of riding. now don't ride anywhere near as far of the back but sometimes on the really steep stuff my arse does feel close to the tyre at times. i'm talking about a really steep feature in a trail here , not just a normal steep descent.
Think of it as an extra brake.
Agree with Northwind - I have got an unfeasible massive arse and mine has never made contact with my rear tyre. (nor the front)
It sometimes happens to me on my FS 29er. Mainly when going down steep and bumpy stuff fast. Hit a bump, suspension compresses and legs do as well. It is better to collapse so your arse hits the wheel than so your nuts hit the back of the saddle.
Have had the tyre buzz my back side on my Codiene 29.
But its only really during those "aww **** that's the wrong line" moments where I'm just trying to save my teeth

both those are better options than going out of control down some rock with your nuts hitting the tyre, that was painfull.
Yes it happens a bit more to me on my 29er than it did on the 26er, and a bit more on the FS 29er than the HT 29er (I think I move about more on the FS 29er as I seem to appreciate the longer dropper I have, which I never miss on the HT if that makes sense).
It's the only downside I can see, but I'm 6 feet tall, I can see smaller people having more issues (which does kind of make me wonder why more companies don't make 79ers or 69ers).
Wow you must have to have your weight way back to catch your nuts on the tyre.
Have you ever got the back of the saddle stuck up the leg of your shorts? I once rode with shorts that were too short (or perhaps too flexible) and this happened. It is surprisingly difficult to control the bike once you get back on flat ground.

It's more going over obstacles than going down steep bits I find.
I haven't caught shorts on the saddle, however having caught them on bottle cages (yeah I dunno) and bars (again, somehow saved that one but no idea how it actually happened) I can imagine it'd be a bit inconvenient!
Yes it happens more on a 29r as the wheel is bigger. I find you cant suck the bike up as much, and need to be slightly more aware of where your ass and the tyre are on some obstacles.
Nothing wrong with moving your arse over the rear tyre at the right time.




Only happens when I’m hanging too far off the back and serves as a nice reminder that I need to get my weight a little further forward for better control. Actually improved my riding and don’t crash half as much when it gets steep and techy now
Happened to me a lot when I moved to the Aeris AM9. 150mm travel + 170mm dropper + deep BB drop, makes sense then. Was a nice reminder that with these very long and slack bikes you don't need to hang back nearly as much as before
