Yesterday I got my first puncture on my new Haibike SDuro AllMtn 6.0. I was 12 miles from home but not a problem as I had all my kit in my backpack and I have fixed dozens if not hundreds of punctures in my time. 10 minutes and I'll be back on the road. Or so I thought!
To cut a long story short it took me almost two hours to fix the damn thing! Or rather it took me five minutes to fix the puncture but an hour and 45 minutes to get the tyre off the rim and back on again. And believe me I know most of the tricks - pinch and push to gather all the slack, tried it, push the tyre into the centre of the rim all the way around, tried it, bit of lube along the beading to help get the tyre back on, tried it. I'm telling you these have to be the tightest fitting tyres in the entire known universe! It took me ten minutes just to get the tyre lever under the tyre let alone begin to unmount it. On two occasions I almost admitted defeat and was going to call a friend to give me a lift home but I pressed on determined to not let it beat me. Such was the effort and force required to get the tyre back on the rim when I finally got it back on I literally fell backwards and collapsed in a heap on the floor!
So at least I now know that it is physically possible to get the tyre back onto the rim but the idea of having to do that on a regular basis is unthinkable. I'm pretty sure the rims and tyres are tubeless ready so I'm thinking of getting my local bike shop to convert them to tubeless.
Any advice and to what extent does tubeless with sealant protect MTBs from punctures?
Also if you do get a puncture in a tubeless set-up with sealant, and you have to effect a roadside repair, by putting in a tube, how messy a job is it with all that sealant sloshing around?
