Session
Algupära
Session on Trek'i allamäge võistlusratas, mida on toodetud katkematult alates 2003. aastast ja mis on üks enim autasustatud platvorme maailmakarika ajaloos. Aaron Gwin võitis kaks üldist maailmakarika tiitlit (2011, 2012) süsinikust Session 9.9 rattal Trek World Racing meeskonnas; Rachel Atherton, Tracy Moseley ja Gee Atherton saavutasid kõik poodiumi- ja üldvõidud sellel platvormil aastatel 2009-2015. Viimane põlvkond läks üle kõrge pöördepunktiga, 200 mm käiguga konstruktsioonile, millel on tühikäigurull, asendades pikaajalise ABP-ainult paigutuse, et järgida Commencal'i ja Norco poolt maailmakarika eesotsas seatud trendi. Trek reklaamib praegu seda ratast Trek - Unbroken DH lipu all koos Oisin O'Callaghaniga. Session on väikese mahuga tipptoode – Trek müüb üle maailma vaid mõnda terviklikku ehitust (Session 8 GX, Session 9 X0) pluss raami, ja enamik omanikke on pargisõitjad, võistkonna eraisikud või kollektsionäärid.
Tehnilised andmed
- Raam
- Alpha Platinum Aluminium, high-pivot suspension with idler pulley, ABP (Active Braking Pivot), magnesium rocker link, Mino Link geometry adjust + progressivity flip chip, ISCG 05, 157x12 mm rear thru-axle (older 2003-2022 gen had OCLV carbon option)
- Kahvel
- RockShox BoXXer, 200 mm travel (Ultimate w/ Charger 3 damper + DebonAir+ on Session 9; Select+ tier on Session 8)
- Jõuülekanne
- SRAM GX DH 7-speed (Session 8) / SRAM X0 DH 7-speed (Session 9), downhill-specific cassette
- Pidurid
- SRAM Code 4-piston hydraulic disc (Guide RSC on older builds), CenterLine rotors 200 mm front / 180-200 mm rear
- Rattad
- Bontrager Line DH, 29", Boost 110 mm front / 157 mm rear hubs
- Vedrustus
- Full-suspension downhill, 200/200 mm front/rear travel, high-pivot rearward axle path. Rear shock: RockShox Vivid Ultimate (current gen) / Super Deluxe Ultimate DH 225x70 mm (prior gen)
- Geomeetria
- Slack ~63° head angle, long wheelbase, 200 mm travel, dedicated downhill race geometry; Mino Link flip chip adjusts geometry, second flip chip tunes suspension progressivity (20% plush / 25% efficient)
- Kaal
- ~17.7-17.9 kg (Session 8 GX complete build)
Verdikt
- Holy-fast high-speed stability — long wheelbase + slack head angle let it carry momentum through the roughest terrain with total composure.
- High-pivot suspension with idler is smooth as butter, soaks up choppy braking bumps and square edges with minimal pedal kickback or foot feedback.
- Inspires huge confidence on steep, fast race tracks — a genuine World Cup-proven gravity sled.
- Mino Link plus a separate progressivity flip chip give meaningful geometry and suspension-feel tuning.
- Trek's lifetime frame warranty (25-year track record) signals real durability confidence.
- Heavy — ~17.7-17.9 kg on the GX build; light riders feel the mass more than heavier riders do.
- Awkward and long-feeling rear end in tight, slow technical corners and switchbacks; not nimble at low speed.
- Stock 180 mm rear rotor is undersized for sustained downhill braking — reviewers want 200 mm.
- Stock handlebar sweep/rise drew criticism; testers swapped bars to dial in fit.
- Single-purpose: pointless without lift or shuttle access, no climbing ability, and not the best choice for jump-focused riders.
