Pressure in CX tyres
I just about to pick up my 1st CX bike, it comes with 32mm clinchers. I weigh in at 80kg and will be riding it mainly on bridle ways, forest single track, towpaths etc.
What’s a good starting point for pressures in the tyres?
Anyway of making them more puncture resistant too? I run tubless on my MTB’s, is that an option – ghetto style?Posted 4 years agogears_suckMember
Depends. Are you a lump on the bike or not. Doesn’t matter what you put in them if you bang it around. However, if your light and nimble, you’ll get away with running lower pressure. It’s a bit of a compromise because if you do want to climb loose or technical stuff, you could drop it a little to get a bigger contact patch. If you’re on smooth and hard stuff all the time you’ll want harder tyres for speed.Posted 4 years ago
There’s such a broad window it’s no possible for someone to tell you what’s right unless they’re out watching you.pixelmixMember
For bimbling around on part gravel / part tarmac commute, 35psi. For racing on muddy off camber courses, about 25psi.
Tubeless setup (Crest rims and regular CX tyres) and a skinny 5ft7 rider here.
Too many variables to say a precise PSI, but I highly recommend going tubeless and dropping a few psi if you want some grip on off camber muddy CX courses.
Can’t believe some of the PSIs above! I guess that is the price of running tubes.Posted 4 years agocrikeyMember
50-60 psi, did the 3 peaks, does the road, does the off road.
It’s less the price of running tubes, more about setting things up to do what you want them to do. Bimbling isn’t what my cross bike is for, and off camber courses are a special case. If I’m out for 30-40-50 miles, I’m not fannying about with spongy soft tyres.Posted 4 years agobolMember
I’ve found a reliable (so far) tyre/tube/puncture mix which was to buy the lightest, fastest tyres I could (won’t be riding it in the mud all that much) and put a Panaracer Kevlar tyre liner between tyre and tube. I’m running circa 80 psi on my commute, and 50ish for playing. I’m pretty new to this myself though, so don’t really know what I’m talking about.Posted 4 years agosimon1975Subscriber
I just bought some cheap shwalbe cx pro’s , which state a max pressure of 65 psi
I hope those were very cheap, I’ve got the Schwalbe’s which go to 90 so I use all of that in the rear and around 75/80 up front. But I hop a lot of kerbs etc so don’t want pinches, and I want the cx bike to be fast!Posted 4 years ago
