[2021 NEW] Rinasclta 2021 Upgrade 29er Carbon Fiber Mountain Bike Hardtail Frame with QR & Thru Axle Interchangeable

Mountain bike is one of the most popular bikes in the cycling industry. While some prefer Quick Release with the old wheelset, some use thru-axle to gain more confidence during mountain riding. Based on this demand, we upgrade our 29er MTB frame with a lower seat tube stay, which will significantly improve the comfortability during XC or off-road.

Thanks to Toray high quality T800+T1000 carbon fiber, we are able to offer a lightweight yet stiff carbon frame without losing any durability.

    Very good frame, and an excellent Rinasclta! Shipped extremely quickly. Well packaged. Prompt communication with clear answers. I’ll be shopping with them again!

  2. Mckenna Holder

  3. Ivan Morton

    Excellent picture very nice and strong strong lightweight shiny black fins with contrast matte looks very good dark aggressive very well done perfect. Watch out for the issue of inposts in your country.

  4. Kayley Ramos

    The frame arrived in 2 week and well packed, it is very well constructed, mounted without problems, just the cable routing below the BB are a bit stiff and it reflects in hard gear shift, but I’m very satisfied, not yet used on trails, hope it will be good as beautiful
