As a source factory with over a decade of wheel set production experience, KOIBIKE specializes in integrated manufacturing of rim production, wheel building, and spoke lacing, offering professional OEM/ODM/OBM services. We are proud to launch the D28X30TL/HL-UL mountain bike wheel set: featuring a 28mm depth design that balances rigidity and low wind resistance, paired with a 36mm external width and 30mm internal width to fit various specifications of mountain bike tires—catering to both off-road enthusiasts seeking wide-tire grip and speed-focused riders preferring narrow tires, while delivering maximum stability and handling in complex terrains. The ultra-light version weighs only 480g for efficient climbing with reduced fatigue, and the standard version at 530g strikes a perfect balance between lightweight performance and cost-effectiveness. Equipped with a standard disc brake system, it delivers powerful braking force and precise control, remaining reliable even in rainy, muddy, or other harsh conditions to ensure riding safety at all times. This wheel set is the optimal choice for high-adaptability and high-performance mountain biking, ideal for B2B clients, individual buyers, bicycle shops, and team purchases.

* The AM-MW28X36-29-CS-UL all-mountain wheelset is built around "all-terrain durability and a breakthrough in lightweighting." Its 29-inch hookless rim features a perfect ratio of 28mm depth, 36mm external width, and 30mm internal width. Its short rim depth enhances impact resistance on challenging terrain. * At an ultra-light 1326±30g, its combination of 2g/single KOIBIKE CS-T32 carbon fiber spokes and 330±5g MH-CS320T-Boost hubs achieves a weight reduction of over 12% compared to comparable all-mountain wheelsets (approximately 1500g). *Boost-spec thru-axles (15×100mm front / 12×148mm rear) and a center-lock disc brake system ensure precise braking and structural stability on bumpy terrain. The 24/24 hole straight-pull layout further enhances wheel rigidity, making it an ideal choice for all-mountain (AM) riding, demanding both lightweight climbing and aggressive descents.

This carbon bottle cage is designed with "extreme lightweight and easy installation" in mind. At 10.9g each, it's 15%-20% lighter than similar carbon bottle cages. Leveraging the high modulus of Toray's T700-grade carbon fiber, it maintains a clamping strength exceeding 200N while reducing weight. Its innovative upper and lower double-hooked design, with the upper hook 2mm deeper and the lower hook 1.5mm wider, creates a "hugging and lifting" dual-locking structure, ensuring the bottle remains stable even on bumpy mountain roads or high-speed highway rides. Mounting to the frame requires only two screws, taking less than a minute. It fits standard bottle cage mounting holes on most road, mountain, and commuter bikes, offering a balance of performance and practicality, making it an ideal choice for those seeking lightweight cycling.

*The DW35X28TL-CS-UL wheelset features a "35mm low-profile aerodynamic + all-around adaptability" design. Its optimal ratio of 28mm external width to 21mm internal width maintains the nimble handling of a low-profile wheel while optimizing aerodynamics through its U-shaped cross-section. At 15° crosswind, drag is reduced by 12% compared to a straight-sided wheel of the same height. *With an ultra-light total weight of 1039 ± 30 grams (rim + hub + spokes + nipples), paired with 3g/single CS-R38 carbon straight-pull spokes and 279 ± 5g KOIBIKE RH-CS275 hubs, the wheelset's rotational inertia is reduced by 25% compared to a comparable steel-spoked wheel, resulting in a more responsive acceleration. Compatible with tire pressures from 50-80 PSI and 25-40C tires, it features a 12x100/12x142mm thru-axle and center-lock disc brake system. *Compatible with Shimano HG/MSR, Campagnolo N3W, and SRAM XDR cassettes. Its uniform black design combines performance and style, making it a versatile choice for road racing, gravel riding, and long-distance endurance racing.

How can you enter the wild world of mountain biking without the KOIBIKE XC-M20X36HL-29ER cross-country mountain bike rim? The 20mm low profile design gives the rim agile handling, like a cheetah darting through the forest. The extra-wide 36mm profile maximizes contact with the ground, boosting grip and ensuring rock-solid stability even in challenging terrain. At only 285±15 grams, it's featherlight, accelerating like an arrow and climbing like a flat surface. The hookless construction optimizes tire contact and reduces rolling resistance for a more effortless ride. The disc brakes provide instant braking response and worry-free safety. The classic UD paint job exudes a carbon fiber texture and is durable and scratch-resistant, making it a reliable and dazzling companion on your mountain adventures.

This 45mm lightweight disc brake road rim is made from Japanese Toray carbon fiber cloth for enhanced rigidity and lightweight performance. Its UD paint finish creates a simple carbon texture, balancing durability with visual appeal. Its 21mm internal width is compatible with tires from 23-47cm, making it suitable for a wide range of riding situations. Its 30mm outer width, combined with a 45mm rim depth, provides ample heat dissipation while balancing aerodynamic performance and maneuverability. The 28mm brake track is specifically designed for disc brakes, ensuring stable and rapid braking while minimizing rim damage. Its lightweight design, with a single-turn weight of 360±15g, reduces rotational inertia for more agile climbing and acceleration, making it ideal for both racing and training.
