The Session 9’s frame is made from Alpha Platinum Aluminium and features a high bottom bracket and a pulley. The integrated frame protection and the option for internal or external cable routing provide additional protection and flexibility. The magnesium derailleur hanger, the Mino Link system and the ISCG 05 2-hole mount are further features that underline the frame’s versatility and adaptability. The Active Braking Pivot system and the 157 x 12 mm thru-axle offer stability and control on descents, whilst the generous 200 mm travel ensures excellent shock absorption.

The bike’s maximum load capacity is 136 kg, whilst the bike itself weighs in at 17 kg. This makes it robust enough for demanding rides without compromising on manoeuvrability.

The Session 9’s brakes are by SRAM and consist of Code RSC 4-piston hydraulic disc brakes. Both the front and rear brakes are fitted with 6-hole discs, with the front brake discs measuring 200 mm in diameter and the rear ones 220 mm. This combination offers excellent braking performance and control in any situation.

Shifting is handled by a 7-speed SRAM X01 DH shifter, which, in combination with the SRAM PG-720 cassette (11–25, 7-speed) and the SRAM PC-1110 chain (11-speed), enables precise and reliable gear changes. The crankset consists of an SRAM X01 DH with an aluminium chainring (34 t.) and a crank arm length of 165 mm.

The RockShox BoXXer Ultimate fork, featuring DebonAir suspension and Charger 2 RC2 damping, as well as 200 mm of travel, ensures excellent suspension and control on rough terrain. The pedals are Wellgo MG-1s with a magnesium body and a CrMo axle, which provide additional durability and grip.

The handlebars are Bontrager Line Pro made from OCLV carbon, with a width of 820 mm and a rise of 27.5 mm, whilst the stem is a Bontrager Line Pro Direct Mount with a length of 50 mm. The grips are Bontrager XR Trail Elite with a nylon clamp, offering additional comfort and grip.

The wheelset consists of Bontrager Line DH 30 wheels, which are tubeless-ready and feature a 6-hole disc mount. The front hub is a Boost hub with a 110 x 20 mm thru-axle, whilst the rear hub is a Rapid Drive 108 with a 157 x 12 mm thru-axle. The saddle is a Bontrager Arvada with austenitic rails and a width of 138 mm, mounted on a Bontrager Rhythm Elite seatpost with a diameter of 31.6 mm and a length of 330 mm.

The bike’s geometry is designed for performance, with a reach of 45 mm, a stack of 63 mm and a seat tube length of 42 mm. The head tube angle is 64 degrees, whilst the seat tube angle is 62 degrees. The head tube length is 12 mm, the chainstay length is 44 mm and the standover height is 76 mm. The bike’s overall wheelbase is 124 mm.
