A136🚴♀️This is an ultra-short stem with a 35mm clamp diameter and 35mm length. With the growing popularity of carbon fiber mountain bikes—and some concerns about their strength—many carbon handlebars have adopted a 35mm clamp to increase stiffness. This colorful 35mm aluminum stem is the perfect match for these riders and pairs seamlessly with Alu handlebars like the L035 model, which features the corresponding 35mm clamp diameter. 👉 Product link: https://en.koofbike.com/Product_detail/66.html ：https://en.koofbike.com/Product_detail/80.html To be fully transparent, we have ready stock of the A136 stem in multiple colors, but its sales performance has fallen short of expectations. As a result, we've introduced an adapter plate to make it compatible with the mainstream 31.8mm handlebars. Honestly, it remains one of the most beautiful and affordable 35mm stems on the market. So, where is the real market for 35mm handlebars and matching stems? Perhaps there’s a niche we haven’t yet discovered. I’d love to hear your thoughts!
