EF wins on tubeless Vision Metron wheels in Colombia TTT, commits for all time trials

Tips & Reviews

As road tubeless & disc brakes take over the consumer road bike market, the combination is still rare in the pro peloton. So, it was interesting to hear of EF Education First’s team time trial win at the opener of the UCI 2.1 Tour Colombia yesterday, on tubeless Vittoria tires wrapped around tubeless carbon clincher Vision Metron 81 SL Disc wheels. And not just a one-time race experiment, EF has committed to tubeless for the entire 2020 race season for all time trials.Advertisements

The tubeless wheels are Vision Metron 81 SL Disc, the brand’s newest deep section aero carbon wheel built for triathlon & time trial racing. The 19mm internal hooked, tubeless-ready rim is 81mm deep, with an overall 24.8mm width that was optimized for 25c tires. The $1834 wheelset features 2:1 laced straight pull bladed spokes, external brass nipples, centerlock disc hubs, and. claimed weight of 1850g.

As for those tires, the team raced 25c Vittoria Corsa Speed TLR tubeless clinchers with latex sealant. The Corsa Speed was one of the first lightweight, race-ready tubeless road tires available on the market. Its handmade, non-vulcanized 320tpi construction that is much like Vittoria’s tubulars, creates a super light tire (claimed 205g for the team’s 25mm choice) that is more supple than most tubeless options, and with one of the lowest rolling resistance figures in the industry. Of course, the Speed has no puncture protection, so it’s still pretty much a TT race-only tire.

Now in their second generation, the tubeless Corsa Speed TLR gets updated Graphene 2.0 rubber, and a move to black only sidewalls that are better sealed for more user-friendly tubeless experience.

Teams at the Colombian race did not contest the TTT on time trial bikes, so the EF team was racing their Cannondale SystemSix aero road bikes rather than the SuperSlice. The team also uses Vision one-piece bar+stem setups instead of the Cannondale-designed KNOT system, so there were still bits of brake & shift lines poking out of the otherwise internally routed cockpits. And out back, some CeramicSpeed OSPW setups to eke out a few extra free watts.
