The Park Tool BBT-135-12 Steel Bottom Bracket Tool is a heavy-duty workshop tool machined from precision 4140 steel for removal and installation of threaded bottom brackets with 12-notch tool fittings. The BBT-135-12 fits 12-notch fittings with a major diameter of 48–50mm and a minor diameter of 46.3mm, including Praxis Works M30 bottom brackets — a standard found across a wide range of contemporary road and gravel drivetrains. The extra-deep body handles extra-wide spindles, and low-profile walls at the engagement point seat into recessed lockrings that standard-depth tools miss. Three drive options — 3/8" drive, 1" hex, and 36mm wrench flats — handle even heavily seized cups, and integrated threads in the tool body accept the Park Tool BBT-RS Bottom Bracket Tool Retaining System or GPS-1 Guide Pins (each sold separately) for improved stability during service.

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.
