For the marathon rider who covers 80 km or more on hilly courses, where lightness and seated comfort make the difference over the distance. According to Trek, this ML version suits riders from 173 to 180 cm.
A carbon frame designed for XC racing. The Procaliber 9.7 shares the OCLV Mountain frame of the other carbon Procalibers: fibres compacted under high pressure and temperature, layup focused on impact resistance, Trek lifetime warranty. What sets it apart is the kit built around it: Kovee Elite 30 carbon wheels, a one-piece RSL bar-stem and wireless shifting. The IsoBow system, with seatstays that extend past the seat tube, adds controlled vertical flex that eases the back during long races.
| OCLV Mountain (Procaliber 9.x) | Alpha Platinum (Procaliber 6 / 8) | Alpha Silver (Marlin) | |
| Level | Trek's mountain bike carbon, lifetime frame warranty | High-end aluminium | Entry-level MTB aluminium |
| Construction | OCLV process, layup focused on impact resistance, IsoBow | Internal cables, threaded BSA, UDH | Simple, robust design |
| Reference bike (M) | Procaliber 9.7: 10.58 kg | Procaliber 8: 12.78 kg | Marlin 7: 14.15 kg |
| What it means | Lighter, rear end flexes over bumps | Heavier, no IsoBow | Versatile, noticeably heavier |
Put simply: this 9.7 is the lightest Procaliber in the range, at 10.58 kg in size M. It owes that to its carbon wheels, its Sainte-Anne RSL tyres with 220 tpi casing and its carbon bar-stem; with an identical frame, it saves 1.55 kg over the Procaliber 9.5 with Judy Gold fork.
In a marathon, fatigue builds up over the hours: IsoBow absorbs some of the vibration your back takes while seated, and the Verse Short Elite saddle with magnesium rails supports the pelvis well. The thick-foam ESI Chunky grips also reduce numbness in the hands.
The four-piston Motive Bronze brakes bring power and endurance on long descents, with 160 mm SRAM CenterLine rotors, a light format typical of cross-country. The 34-tooth GX Eagle chainset and 10-52 cassette offer tall gearing for the fast-rolling sections of a marathon.
| Model | Frame | Drivetrain | Fork | Weight (M) |
| Procaliber 9.6 | OCLV Mountain, IsoBow | SRAM Eagle 70 T-Type 1x12 | Fox Factory 34, 130 mm | 12.38 kg |
| Procaliber 9.7 (RSL tyres) | OCLV Mountain, IsoBow | Wireless SRAM GX AXS | SID 120 mm | 10.58 kg |
| Procaliber 9.7 (Rekon Race) | OCLV Mountain, IsoBow | Wireless SRAM GX AXS | SID 120 mm | 11.38 kg |
| Supercaliber SL 9.7 (full suspension) | OCLV Mountain | Wireless SRAM GX AXS | 80 mm rear / 110 mm front | 12.18 kg |
Our take: for a marathon, this 9.7 remains the lightest hardtail in the range. If you want more comfort at the rear, the Supercaliber SL 9.7 GX AXS adds 80 mm of travel for 1.60 kg more.

LVR sizing advice The one-piece bar-stem cannot be changed as easily as a conventional stem: its length follows the size (70 mm from S to ML, 80 in L, 90 in XL). Between two sizes, we prefer to confirm the position in store before deciding.

| Only in ML? | Yes, this colour is offered in ML; the navy blue covers S to XL. |
| AXS battery life? | It lasts several long rides; charge it the day before a marathon. |
| Are the ESI grips comfortable? | Yes, their thick foam damps vibration; they wear over time and are easy to replace. |
| Is the smoky red fragile? | Clean it with a gentle cleaner; frame protection can be applied at rub points. |

The LVR Cycles verdict A Procaliber 9.7 designed for long distances, as light as it is enduring thanks to its four-piston brakes. Its smoky red gives it an intense, refined character.
