I’ve been using 650×47 Gravelking SKs (run tubeless, obvs) since I first re-purposed an old 26″ MTB as a gravel bike back in 2018. I’ve had the odd pinch flat, but on the whole been pretty impressed with how they’ve held up. Roll well, grippy enough, seemingly tough enough.
A couple of months ago I swapped to a more conventional gravel bike – a Genesis Fugio, which I’ve stuck my old old wheels on as they were significantly lighter. Since then, I seem to be averaging a pinch flat/ride – many more of which are front wheel ones, which is highly unusual. I think I’m riding a bit faster, but I’m aware by descending in the drops that I’ve got a lot more weight on the front wheel.
It’s always similar conditions – fast, difficult light (dappled mostly) chossy rubbly trail (the kind of trail that was “gravel” but all the fines have been washed away) and I just smash straight into something a bit pointier than all the other rocks that I haven’t even begun to have seen and the tyre is flat as a pancake 30′ later. Today’s effort was coming down Coombsdale in the White Peak.
I’m running 32psi front, 40 rear.
So any recommendations for something similar to a Gravelking that’s a bit less fragile? Must be 650b…
Thanks!
