gator skin tire

I have had gatorskin tires for several years. They are by far the best tire.

Great wheels

Nice and light but plenty stiff. Great for all around riding on my Epic Evo.

S Works Prevail 3 Fits Like a Glove

The S-Works Prevail 3 is one of the most comfortable bike helmets I’ve worn. The fit system adjusts perfectly, and once I ratchet the MIPS cradle to my head, the helmet almost disappears — it conforms so well that I barely notice I’m wearing it.

Ventilation is excellent. Riding in moderate weather around the mid-70s, my head stayed cool and comfortable without overheating. The airflow design really works.

Thankfully, I haven’t had to test the helmet in a crash, and I hope I never do. But the build quality and design give me a lot of confidence in the protection it offers. Highly recommended.

Amazing frameset - shipped fast - great pricing

Very impressed by the whole experience with Sierra Bicycle Supply! The frameset was just as shown - brand new and gorgeous. It shipped fast with tracking info. Great pricing on the frameset and I picked up other stuff for my build. Great overall experience - highly recommended!!

Really is a Bike Computer / display brighter than s25 Ultra

Here is how I am using it.
- Customizable displays for ...
- Heart Rate Sensor
- Garmin Pedal Power Meters
- Lights control
- Cadence Sensor
- Speed Sensor
- DOES NOT WORK WITH SAMSUNG WATCH 8 CLASSIC
- Records Route Creation but need to be careful with saving rides as not doing two rides back to back = lost
- does not come with a one hundred twenty page manual.But I was able to find a pdf file online
