Mechanical disc brake maintenance

Hey Lee,
Quick question: I recently got my first disc-brake mountain bike and it rocks. I’m using cable brakes instead of hydraulic. Is there any special maintenance I have to do with disc brakes that I don’t do with rim brakes.
Thanks,
Alex

Which size 29er?

Lee – Good day! I wondered if there was any science to the sizing of 29er frames. There does not appear to be much in the way of resources available on the subject and the manufacturers occaisionally list recommended rider sizes for frames but leave the fit to the Local Bike Shop. In looking at Titus frames, for example, the large 26er frames closely match the dimensions (effective Top Tube, that is) of the Medium 29er frames. In choosing a 29er frame, is there any reason not to maintain the same effective Top Tube as one would on a 26er?
Thanks,
Jeff

How much rear travel do you need for DH?


Hi Lee,
I am interested in purchasing a new DH race steed. I am a competitive expert racer and I was wondering if a 7-inch bike would be a major disadvantage on MSC and G3 racecourses. I am specifically looking at the Commencal Supreme DH, which I understand a few of the WC teams are running. However, I am still skeptical of a 7-inch Down Hill race frame. I am not the gutsiest or smoothest rider, but I very much enjoy going fast down a racecourse.
Thanks For Any Advice,
Jeff
P.S. I appreciate what you are doing for the mountain biking community!

Stems: How short is too short?

Lee,
I’m taking your advice and installing a shorter stem. My question is “how short is too short?” I’m riding a Giant Trance with a 110mm stem; would going straight to a 40mm stem be too big a change? Or just too short for the bike?
Thanks! Dan

Effect of DH tire size?


Hey Lee,
Got a quick question about tire pressure. I’ve been running Kenda Blue Groove 2.7’s up front for years and wanted to switch to a 2.5 for racing. My problem arises when I try to run the 2.5 I cannot seem to find the correct pressure to work like the 2.7. My setup for the 2.7 is PSI = 18-20, for the 2.5 I’ve tried the same pressure, even a bit higher and lower but nothing works. With the 2.7 I can corner like mad, leaning the bike hard, but on the 2.5 my front washes, same trails, same riding position, same suspension setup, same everything, just different tire. What gives??? I’m at a loss! Thanks Lee.

Sincerely, David

Which size Trance?

Hey Lee,
Thanks for all the support & efort you put in to the sport. I am looking at the new Giant Trance x1, and fall between the medium and large frame size (I’m 6′ tall with a 32″ inseam). What are the pros and cons of going either way. I ride xc, but enjoy the tech and down more than the up.
Thanks again, Daniel

Rigid fork for pump track action?

Lee,
What are your thoughts on a rigid front fork for a dedicated pump track bike? I’m thinking that a rigid fork (like a DMR Trailblade 2) would be better for pump track riding than even a stiff suspension fork. Thoughts?

Manuals: Help, I’m tipping over!


Hey Lee,

Love your site and the book, great work on both mate.

I guess this has probably been done to death but im having alot of trouble with manuals and wheelies. Getting the front up and balancing front to back is easy, my problem is I always tip over sideways! People say move your hips and stuff, which ive tried…but once I start to go I just cant correct it.

Any ideas?

Cheers, Ash
