The high-performance wheels really exceeded my expectations.

I’m very happy to share with you a piece of good news: I placed 5th overall and 1st in my category at the Diessener 12-Hour Mountain bike European Championship. I rode Light Bicycle’s XC925 Flylight rims and they really exceeded my expectations.

In case you have no knowledge of this contest, let me give you a brief introduction. This grueling race has only one goal: to complete as many laps as possible within 12 hours. The 7.2km course consisted of gravel, meadow paths, and rooty trails.

I have never raced longer than 6 hours before so I was in for a challenge!

One hour before the race started, my friend Erik Hühnlein and I decided to race in the solo category instead of the 2-man team. Erik was in the Masters 2 category and I was in Masters 1, so we thought it would be fun to ride together since we were in different categories.

The race started at 8:00 am, the weather was good and the temperature was 20°C. There were a couple of facts we had to keep in mind: Don’t go too hard off the start, try not to exceed our personal FTP too often, have fun! We had an excellent support person (Conny!) providing us with all of the fuel we needed for such a long race and plenty of vocal encouragement to help motivate us.

I realized how important it is to have a good support team around you.

The first 5-6 hours went by without any issue. Then it started to rain and some problems with my stomach arose. With thoughts of quitting reeling through my head, it wasn’t until Conny let me know I was leading my age group that I regained my focus.

Soon the rain stopped, and my stomach eventually calmed down after copious amounts of water were consumed. Erik was also leading his category, and won his Masters 2 category. I held on to win Masters 1. In 11 hours and 51 minutes, I completed 37 laps, 270km and 4800 meters of climbing, three laps ahead of the second. I could not have done it without Erik and Conny cheering me on and keeping me well fed and motivated.

Also many thanks to these high-performance wheels. Throughout the race, the incredible wheels felt super light, durable, stable, and rolled smoothly. I’m completely satisfied with them and highly recommend them to any XC mountain bikers!
