TrekSpeed Concept TT

Time trial20263rd generation (Speed Concept 3.0) ↗Disc brakesUCI legal

The time-trial version of Trek's third-generation Speed Concept. It shares the 800 Series OCLV carbon frame with KVF tube shapes and the integrated full-foil fork and stem of the triathlon SLR, but leaves out the triathlon storage and uses a slacker 76-degree seat angle with a lower, longer front end. Trek sells it only as a frameset, in three sizes, with the size-specific cockpit and seatpost bought separately.

Our verdict

No overall score: there's no complete-bike price to rate

The UCI-legal sibling of Trek's Speed Concept SLR: the same light OCLV frame and integrated fork and stem with a time-trial seat angle and lower front end. It is frameset-only in three sizes, with no storage or hydration and tyre room capped at 25 mm up front, so it suits time triallists more than triathletes.

  • Fit

    Trek's size chart puts the S at 154-167 cm, the M at 167-175 cm and the L at 175-186 cm rider height; the TT frame is not offered in XL.

    Source

  • Compatibility

    Trek lists maximum tyre widths of 25 mm front and 28 mm rear, 160 mm maximum rotors front and rear, and maximum chainrings of 58T for 1x or 55/47 for 2x.

    Source

  • Versions

    Compared with the triathlon SLR frame of the same size, the TT frame has a 76 rather than 78-degree seat angle, a 72-degree head angle, 7.2 cm rather than 8 cm of BB drop, and a lower stack with a slightly longer reach (size L: 533/434 mm against 541/426 mm).

    Source

  • Versions

    When you buy a Speed Concept frameset, Trek sells the size-specific seatpost and cockpit parts separately so they can be matched to the rider.
