The Park Tool GPS-1 Five-Piece Bottom Bracket Tool Guide Pin Set is a complete set of guide pins for improving stability and alignment during bottom bracket removal and installation with compatible Park Tool bottom bracket tools. Each of the five pins in the GPS-1 is sized to a different common thru-axle hub or bottom bracket spindle standard, giving mechanics coverage across a wide range of modern drivetrains in a single set. Each pin threads into any of the thirteen Park Tool bottom bracket tools that feature integrated threads, using a 5mm hex fitting at the threaded end for installation and removal without additional tooling. Once seated, the extra-long pin — with a usable length of 61mm (2.4") — engages into the bottom bracket or hub to hold the service tool in alignment and reduce the risk of misalignment during torque application. The GPS-1 is sold as an accessory to the compatible Park Tool BBT-series tools; those tools are sold separately.

Fast shipping and perfect frame set as described. It's literally the lightest built MTB I've ever felt. My wife will be smashing on it at this year at the Leadville 100. LFG Thanks guys!
The battery does exactly what it is supposed to. 50% more juice for those longer rides. The purchase experience was disappointing. The website says "Ready for pickup in 2–4 days — Or ships today" In reality, it shipped more than a week after I placed the order.
The CLX III are exceptional I was a little apprehensive about buying them having ridden the Enve 4.5 but you feel less crosswinds and their lighter and spin fast. The spokes seemed to offer a lot of dampening vibration. Win win in my book.

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.
