Exactly what I needed for my custom build. Frame and fork arrived well-packed. Assembly was straightforward, everything fit as it should. The red color looks even better in person. For the money, it's a steal.

Upgrade from an old aluminum frame. The difference is night and day! This carbon frame eats up trail chatter and feels so much more responsive. The bundle made everything easy. Highly recommended for anyone looking to step up their hardtail game.

Finally pulled the trigger on a carbon hardtail project. This frame/fork combo was the perfect foundation. The quality is there – nice finish, good tolerances. The included bits (headset, seatpost) saved me a ton of time and money. Stoked!

Built this up as a lightweight trail ripper. The geometry is spot-on – playful but stable when you need it. The fork is solid and the weight savings over an alloy setup is immediately noticeable. Fantastic value.

Super impressed with this bundle for the price. The SDY21 frame is crazy light and the full internal routing makes the bike look absolutely pro. Paired it with the TMK200 fork for a super nimble hardtail build. Zero complaints.
