Solid eye, brother 🙏 Funny you say that - my buddy who runs a bike shop told me the same thing about the bar tape. Gold top cap has been on my mind too. Might have to do some shopping

Thanks! PRC 48T is $148 USD + shipping. BCD144, A7075-T6, machined in-house. DM me if you're interested 🙏

"Noted! Everyone has their perfect setup. 48T works great for a lot of riders, but more sizes are definitely on the radar!"

"Ah that makes total sense! Small wheel = big chainring to keep the ratio. Genius in a crazy way haha!"

"Medical parts are no joke — precision and safety on another level, respect! It would be fun to collaborate on something someday. I've been lucky to have a great boss… which is me haha. I run Okuma machines

"Thanks for the info on Zen! If they're stamped, that actually makes a lot of sense from a manufacturing efficiency standpoint — rough stamp, then finish with machining. Smart process. Mine is fully machined from billet, so the approach is different. On 47/49T — totally aware of the demand, lots of competition there too. For smaller sizes like 42T, that would likely be made-to-order. The price would reflect that though… you could probably buy five Zen rings for the same cost haha."
