Being new to tubeless - what brings about a slow leak in a tyre? I've had the wheels for about 10 months and had to top up the air every few weeks. Now it's 20% flat after a couple of days. They are carbon rims so I don't think you can dent them - is it possibly a smallish hole in the tyre or more likely rims? Any thoughts would be appreciated.

Gday fellas just got a little question for you guys (and girls).

I bought a new 10 speed shimano xt chain to replace my cheese cutter kmc and wondering if anyone has any tips for the install? Can i cut to the same length as my old chain or will stretching make it difficult? Also can i reuse the quick link and are different brand quicklinks interchangeable?

Thanks,

Jono.

Need some help. When pumping air into my fork it seems ok until it reaches around 60psi. Then as I try to pump more air it shoots up to 100psi. I can feel quite a lot of resistance if I try to pump any more . The needle on the gauge gradually goes down. I've tried another pump but same thing. Is the air not going into the fork but just filling the hose on the pump? Any help appreciated

I've had the chance to play with some Rubena tyres over the last few months on the 29er.

For the racer boys, I'd add that they perhaps don't roll quite as fast as a Rocket Ron + Racing Ralph combo, but if you're after a robust set of training tyres that give good grip and wear, they're a good buy.
