    I’ve been running the GMD-27s for 50+ mile back country mountain bike races, and I must say: these wheels are the perfect weapon for the kind of riding that I do! Not only are they super light and nimble on the climbs, but the burlier nature of the wheel allows me to rip down some serious gnar with full confidence!

I love my GME-30's, I immediately felt the faster acceleration once I put them on.  The stiffness paired with the weight is great! They're also way stronger than I was expecting, I had a really hard case and the wheel is still running perfectly true!

These wheels felt great on my first ride. Super responsive. Cornering felt fantastic. I thought being stiffer they would beat me up a little while climbing rocky terrain, but I didn’t feel that. The overall ride just felt better. I rode Kitsuma in Old Fort, NC which is a notoriously fast trail so I put them to the test for sure.”

-Nick Pace

I have been enjoying my PNF Enduro wheels. They track well and keep a good tire contact to the ground through tech DH and climbing. The carbon woven spokes are tough as nails. People get hesitant when they hear carbon spokes but these cut into a branch that got sucked into my wheel with no damage, wheel Tru.

-Tim Haggerty

I'm riding the GME-30's and I couldn't be more pleased with the ride. These wheels allow me to feel the terrain so directly that I can anticipate and quickly respond to changes in traction with my body position. They've conquered the terrain of Pisgah, Windrock, Beech, and Sugar without a hitch. Gulo Composites, thank you for giving me a 6th sense.
