Designed with input from our Enduro World Series teams, the new Arch MK3 is ready to own every trail. WideRight optimized for maximum stability with 2.25" to 2.5" tires, we expanded the internal width out to 26mm while keeping the rim incredibly light. The 27.5" Arch MK3 weighs only 425g. A new proprietary alloy and stronger, low-profile rim shape means the new Arch MK3 is built to last. Featuring Bead Socket Technology, the new Arch MK3 also offers the unmatched traction, control, and reliability only found on genuine Stan’s NoTubes rims.

 The perfect balance of strength and weight
 24% wider than the Arch EX for improved stability with larger tires

 Low-profile shape rolls faster, lasts longer, and helps stop tire pinch flats
 25% stiffer and stronger for improved handling

Hope Pro 4 Hubs - The benchmark in MTB Hubs

The previous Pro 2 Evo hubs were renowned for their incredible versatility, primarily due to their adaptability to any common hub standard. The new Pro 4 builds on this further with a number of technical improvements and spec changes to reflect the growing popularity of road and CX bikes  along with providing increased stiffness to the modern larger wheel sizes, without any weight penalty over the previous Pro 2 Evo's.

Key changes over the Pro 2 Evo include: -
Longer freehub body which is compatible with 11 speed road, traditional MTB, Sram XD & Campagnolo cassettes
Increased flange diameter which provides increased stiffness
New 44 tooth freehub ratchet giving a quicker (8 degree) engagement
Larger inboard freehub body bearings giving improved durability
