Evenin’ all

Headed out on Dartmoor earlier for some interval training on road on my XC bike.

Hitting roughly 40.9 mph on a downhill section I started wondering how quick one can generally (safely) go on off road tyres on road?

Am I heading for a high speed face plant?

No

I’ve done 48mph no problems.
Years ago I read (although I can’t vouch for) that an MTB tyre has to be doing 250mph to aquaplane…..

riding my MTB on the road, I tend to get to around 40 and then start thinking about things like front wheel blowouts, and the the last time i tensioned my self built wheels.

Having said that, I did plenty of overtaking on the Dyfi. Blatting past people on the rough slate side lines only really made feasible by a big bike. Wheels take a hell of a battering but it doesn’t bother me offroad.

Descending the highest pass in the alps i hit 65kph with a bike loaded heavily enough i couldnt lift it. I built those 700cc wheels too! too busy overtaking cars to worry about “whatifs” 😀

Easily topped 40 and nudged 50 before now on the Mtb. Ran out of road not balls other wise it’d be quicker.

Thanks guys. I shall no longer fear the speed…

my only worry when ‘making progress’ on the road is front wheel washout. big brakes, high speed, corners and nobblies have caught me out a few times. -last time was a 40mph slide on a blind bend with no lid 😯

I start to get wary around 40mph because nobly tyres make a hell of a noise at that speed and brake dive is a bit mental, so I lock my fork out for the big hills on the way home from work.
