Trek 2027 Speed Concept SLR 7 Triathlon Bike

Note: This Speed Concept SLR 7 is a Trek Project One build, so what's pictured and specced below is the starting base, not a fixed package. Crank length, bar/stem length, tyre choice, saddle and colour can all be tailored to your fit and riding. Get in touch and our team will help you build the exact bike that's right for you.

The Trek 2027 Speed Concept SLR 7 is Trek's dedicated triathlon and time trial bike, built for racers who want every second back over long, exposed courses. The 800 Series OCLV Carbon frame uses Kammtail Virtual Foil tube shaping to cut drag, while Shimano Ultegra Di2 electronic shifting keeps gear changes precise when you're locked into an aero position for hours. Bontrager Aeolus Pro 51 carbon wheels round out a build designed purely for solo speed, not bunch riding. Like every Speed Concept, this is an aero cockpit and aero frame machine for triathlon and TT racing, and for New Zealand age-groupers building toward Ironman Taupo, Challenge Wanaka or a local time trial series, it's a serious step toward a faster split.

Who Is the Speed Concept SLR 7 For?

The Speed Concept SLR 7 suits triathletes and TT racers moving up from an entry-level aero bike or a road bike with clip-on bars, who want a purpose-built machine without stepping straight to Trek's top-tier build. Shimano Ultegra Di2 gives reliable, precise electronic shifting at a lower cost than Dura-Ace, which makes sense for age-groupers training and racing regularly rather than chasing marginal gains.

In New Zealand this is a solid platform for anyone building toward Ironman Taupo, Ironman 70.3 events or Challenge Wanaka, as well as club members racing local time trials. It's not a bike for bunch rides or drafting, since the aero bars and forward position are built for solo effort, but for anyone training specifically for triathlon or TT racing the SLR 7 delivers genuine aero performance at a more accessible price than the AXS or Dura-Ace builds above it.
