Carbon rims were something that I have never tried on my trail bike.

I started taking part in enduro competitions in 2014. For that time, my bike was pretty heavy with big suspension. It was very fast on downhill sections, but every uphill was a nightmare for me.

I changed a lot of bikes and bought my S-Works Stumpjumper 27.5 in 2019 - light and stiff pocket rocket for all kinds of trails\enduro\jumps lines. This bike has a light and stiff carbon frame, 150mm suspension on front and rear, 11-speed groupset based on Shimano XT (I tried 12-speed Eagle but didn't like it and went back to 11sp), and very powerful Shimano Saint brakes with 180mm rotors. All components were chosen after a few years of riding and only carbon rims were something that I had never tried.

It would be interesting to give the LB rims a try.

When I built carbon rims from Light Bicycle on my Specialized P.3, I thought that it would be very interesting to try them on my trail bike. During an enduro race, you spend many hours on a bike, doing a lot of downhills and uphills, so it's pretty important to be in good shape. You should cope with all the riding easily and a light and fast bike can help you a lot.

I was so impressed that my bike got so much faster.

I laced the rims on Industry Nine 101 hubs and visited my home spot with jumps and fun lines. These light wheels allowed me to ride faster on the same lines without extra pedaling. All turns were so smooth and fast because these wheels are so stiff that you can smash all turns faster than ever. And jumps - the Light Bicycle rims feel so comfortable on it.

At the same time, I saved a lot of grams because I got only 1600g for the carbon wheelset (and the whole bike weighs only 12.92kg!) - that's really impressive, especially when these lightweight wheels are incredibly strong and durable. I'm stoked how fast and comfortable my bike is with these new carbon rims.

See you on the trails, guys!
