Leo ★★★★★

The machining on this aluminum ring is seriously clean, and it bolted right up to my cranks with zero fuss. I went with the 3mm offset for my Boost frame and the chainline is spot on now. Shaved a good chunk of weight compared to my old setup too.

Evelyn ★★★★★

Swapped this onto my bike and the weight difference from my old steel ring is noticeable right away. I went with the 3mm offset since my frame is Boost, and it lined up perfectly with no chain rub. Shifting feels crisp and the machined finish looks way nicer in person than in the photos.

Charlotte ★★★★★

Swapped my old ring for this one on a Boost frame and the 3mm offset lined up perfectly. The machined aluminum feels solid but it's noticeably lighter than the stock steel ring. Only a few rides in, but no dropped chain yet.
