The Fulcrum RM16-TA12135 conversion kit is a high-precision technical adaptation solution for disc brake rear wheels. Designed to convert hub spacing from 12x142 mm to 12x135 mm in thru-axle configuration, this original Fulcrum OEM kit guarantees perfect hub alignment, optimal bearing preload, and uncompromised drivetrain performance. Manufactured to Fulcrum's exact tolerances in Vicenza, Italy, it is an essential service part for demanding mechanics and cyclists concerned with compatibility.

Composition and technical design

• Complete two-component kit (A + B): The RM16-TA12135 consists of two precision OEM alloy elements that together define the hub width at 135 mm in HH12 thru-axle configuration. These adapters are machined to tight tolerances to ensure perfect fit and optimal bearing preload.
• HH12 standard (12 mm thru-axle): Converts the hub to 12 mm thru-axle configuration with an Over Locknut Dimension (OLD) spacing of 135 mm, a widespread standard on modern disc brake road and gravel frames.
• Direct installation: Direct replacement press-fit compatible system that integrates perfectly into compatible Fulcrum hubs without additional modification.

Advanced conversion functions

• Spacing conversion 12x142 mm → 12x135 mm: Allows conversion of a rear hub originally configured in 12x142 mm to the 12x135 mm thru-axle standard. The RM16-TA12135 simply replaces the 142 mm version (RM16-TA12142) to adapt the wheel to a 135 mm frame.
• Base for Quick Release conversion: When combined with the optional KITFCRAQR kit (sold separately), the RM16-TA12135 enables additional conversion from 12x135 mm thru-axle to 10x135 mm quick release, offering maximum modularity.
• Disc brake compatibility: Compatible with 6-bolt or Center Lock disc brake mounting systems, ensuring complete versatility on Fulcrum road and MTB disc wheels.

Extended compatibility with Fulcrum wheels

This adapter kit is compatible with a wide range of disc brake road and MTB wheels from the Fulcrum range:

• Road Disc wheels: Racing Quattro DB, Racing 5 DB, Campagnolo Zonda Disc
• MTB / Gravel wheels: Red Power (HP), Red Passion, Red Power HP XD, Red Passion XD, Red Metal XRP 650B XD, Red Metal 29 XRP XD
• Important note: To ensure exact compatibility, it is recommended to consult the Fulcrum spare parts catalog by checking the product code of the hub of the wheel concerned, as many similar models exist with different compatibilities.

OEM quality and original guarantee

• Original Fulcrum / Campagnolo part: Manufactured by Fulcrum Wheels S.r.l. (Via dell'Economia 103, Vicenza, Italy), this OEM part guarantees impeccable quality and complete compatibility with the brand's standards.
• Exact manufacturing tolerances: Each adapter is machined to Fulcrum technical specifications to ensure perfect hub alignment, optimal bearing preload, and reliable drivetrain performance over time.
• Professional service applications: Used primarily in workshops to adapt hub spacing or as a base component in axle standard conversions, this kit is a must-have for professional mechanics.

Technical highlights
