Paved road mountain climbers

Hi I am training to climb a few in my area. I am riding a Nimbus 24” muni but with the Maxxis Holy Roller 1.85 tire. Along with the challenge of the incline is the damn road camber that I am obviously not used to. Is it a matter of practice, like anything else, for it to get easier? I had the tire around 30psi and I weigh 120lbs. The tire is rated at 60psi....dare I go that high and would it even make a difference? Any help or tips appreciated.

Practice practice practice!

Also yes, consider putting a lot more pressure into the tyre. If it's only 1.85" wide then you really should be running it fairly hard for road riding. Maybe not 60 but 40-50 (Try it and see).

What sort of climbs are you looking at doing? Any idea of distance and gradient?

The one I am practicing now is a 5.1% grade over about 5 miles. The grade on the bigger one is closer to 8% over 6-7 miles which I have no inclination to try until I’ve mastered this smaller one 🙂

On some tires higher pressure can help to eliminate the road camber effect. On my 36er Nightrider tire I run very close to 65 psi. Other suggestions include shifting you center of gravity to the up hill side of the camber.

Hi Donna -
On my Whiteface trip a couple years ago I rode my 29" uni. Just before the trip I purchased a lightweight Schwalbe road tire (doesn't matter which one) that I thought would perform well and it did … until I got to off-camber roads. It was horrible. I found out literally the day before the race. So I went back to a 3" mountain tire which is much heavier but has little to no off-camber feedback.

I'm kinda a tire junkie and have tried quite a few. Some have much more noticeable off-camber effects (on certain rims) than others and there are threads on this forum dedicated to tires and off-camber effects.

The point is, experiment: try it at different pressures to see how it responds. And try different tires if possible. Hopefully you'll find one that rides well for you on your rim. The lightest most road-looking tire may not be the best one for you.

Whiteface Mountain road climb does have three (I think) quite annoying off-camber sweeping turns.

And best of luck in your climbing future!

Try a Maxxis DTH 24 x 1.75
I run one on a 30 mm rim. Don't know how well it would go on a much wider rim.

Very light tyre. Only 440 grams. Makes the uni very responsive.

Low susceptibility to camber.

I ride a Holy Roller on my 26", and it handles road camber fairly well. It helps to have higher air pressure. (I typically run in the 30s when I know there will be road pavement involved, higher if it will be exclusively a road ride.) The tire should handle the rated pressure, but I would recommend experimenting to see what works best for you.
Getting used to road camber is (like everything else uni-related) a matter of practice. Search out one of the many threads on this forum for strategies on dealing with it.
Good luck!
