Giant TCR Advanced 2 vs Cannondale SuperSix EVO 4: Road Bike Comparison for Triathletes

Neither of these is a triathlon-specific bike — both are road race machines that triathletes buy for interval training, long endurance rides, and brick sessions without putting miles on a dedicated TT bike. They sit at a similar price point but make different trade-offs to get there. Here’s the comparison.

Key Specs Compared

  • Price — Giant TCR Advanced 2: £2,299. Cannondale SuperSix EVO 4: £3,000.
  • Groupset — TCR Advanced 2: mid-range drivetrain and Giant alloy wheelset at this entry price point. SuperSix EVO 4: Shimano 105 Di2 electronic shifting as standard — a genuine step up in shifting quality and consistency for the extra spend.
  • Frame — TCR Advanced 2: Advanced-grade composite carbon, the entry point to Giant’s TCR carbon range. SuperSix EVO 4: fifth-generation carbon frame, shared geometry and layup philosophy with the range-topping Hi-MOD models, just with a mid-tier component build.
  • Geometry — TCR Advanced 2: pure road race geometry, add clip-on aero bars for triathlon-style training rides. SuperSix EVO 4: reworked fifth-gen geometry with 10mm less stack and a steeper seat tube angle — a more aggressive, race-forward position out of the box.
  • Aero claims — SuperSix EVO 4: Cannondale claims a 4-watt saving at 45km/h over the previous generation, from narrower cockpit profiles and revised tube shaping. Giant doesn’t market the TCR Advanced 2 on aero numbers — it’s built around stiffness and low weight instead.

Which One Should You Buy?

If budget is the deciding factor and you’re happy with a mechanical or lower-tier electronic groupset, the Giant TCR Advanced 2 gets you the same fundamental race geometry and carbon stiffness as Giant’s much pricier TCR models for £2,299 — genuinely good value as a dedicated training bike. If you want electronic shifting out of the box and a slightly more aggressive, race-ready position without upgrading components later, the Cannondale SuperSix EVO 4 justifies its extra £700 with Shimano 105 Di2 and a frame platform shared with Cannondale’s WorldTour-level builds. Both are genuinely capable of double duty as a race bike if you don’t want to run a separate TT bike for shorter-course racing.

Buying Tips

  • Add clip-on aero bars (roughly £50–150) to either bike if you want to replicate your triathlon position on training rides.
  • Get a professional bike fit before buying — road geometry differs from TT geometry, and the SuperSix EVO 4’s more aggressive fifth-gen position may suit a different frame size than you’d expect.
  • Tredz offers 0% APR finance on bikes over £500, which narrows the practical price gap between the two if monthly cost matters more than the upfront figure.

Care and Maintenance

Clean either carbon frame with mild soapy water — never use a pressure washer directly on the frame or cable entry points. Torque stem, seatpost and bar bolts to the manufacturer’s spec sheet to avoid stressing the carbon layup. If you go for the SuperSix EVO 4’s Di2 groupset, keep the battery topped up — Wahoo and Shimano systems both give plenty of warning, but a flat battery mid-race isn’t recoverable.
