Rock Machine Catt 40 mountain bike Matte Jasper Brown is a 29" hardtail built on an aluminum frame for practical everyday riding. It sits in the mid-performance category, where the focus is on balancing function and price without compromising on core standards. It targets riders who want 100 mm suspension travel and 2×9 gearing for a wide range of routes.
The foundation is a frame made from heat-treated 6061-T6 aluminum alloy, designed for off-road use with easy servicing in mind. The front end is ready for a fork with a tapered steerer, and the head tube is fitted with an FSA No.10 Semi-Cartrige 1-1/8" headset. The hardtail concept prioritizes direct power transfer and predictable tracking on fast gravel roads as well as forest paths. The 2026 model year sticks to current standards for 29" trail-oriented recreational and sporty riding.
Drivetrain: Shifting is handled by Shimano Cues in a 2×9 setup with 36/22 chainrings and an 11–36 cassette range. It uses a Shimano FD-U4000 front derailleur, a Shimano Cues RD-U3020 SGS rear derailleur, and a Shimano BSA bottom bracket.
Brakes: Braking is provided by Shimano MT200 disc brakes. Shimano SM-RT10 rotors measure 160 mm in diameter.
Wheels and tires: The wheels use Stars J20 rims and Shimano HB-QC300 and Shimano FH-MT200-B hubs for quick release. WTB Ranger Comp tires are sized 29×2.3".
Cockpit: One1 Alloy handlebars are 720 mm wide with a 31.8 mm clamp diameter, paired with a TDS-C342 Alloy stem. A Selle Royal Flex Tex SRX saddle is complemented by Herrmans Luna Lock grips.
The RockShox Judy Silver TK air fork with 100 mm travel reduces energy losses on rough surfaces and keeps the front wheel tracking accurately. The combination of 29" wheels and 2.3" tires increases stability over roots and rocks while also helping with traction on steeper climbs. The 2×9 drivetrain with an 11–36 range lets you fine-tune cadence on long climbs as well as on road transfers. The 14.25 kg weight matches a more robustly equipped hardtail and is noticeable when accelerating uphill.
The Catt 40 is for sport-minded riders who want one bike for forest trails, gravel, and longer rides in hilly terrain. You’ll appreciate it if you prefer the simplicity of a hardtail and want functional Shimano components for frequent riding. Within the 29" hardtail category, it offers a combination of an air fork and a wide gear range without the need for specialized service.
