Bought these as the largest tyre that will fit my Specialized Diverge - 33mm. Very nice product. Tricky to fit, burst a few inner tubes in the process, but now that they are on the ride is comfortable and I'm confident on all terrains.

Reviews
Have done a few long rides with these over the last few weeks since I got them and they feel most natural on hard packed dirt roads. On tarmac they are still relatively fast, but fly through dirt and fine gravel very well! Most fun I’ve had in awhile! Construction feels solid and I have not been disappointed with the quality of Challenge tyres. Putting them on rims takes a bit of effort compared to other tyres, but well worth it.

Will it also accept chipping tarmac rough B roads and broken potholed surfaces at speed down 25%+ hills??
Hello, I can confirm that this tyre would work absolutely fine for what you are looking to do. Kind Regards Liam
