Tahnée Seagrave's Transition TS500 World Championship bike

http://ift.tt/2cJ2EGv

Tahnée Seagrave has perhaps the flashiest bike here at Val Di Sole, with a sparkly paint job apparently inspired by someone’s socks — who knew! Beneath the paint is a serious, well tuned machine that should be looking at a podium spot this weekend.

Tahnée runs Fox suspension front and back, with the DHX2 rear shock complementing the Fox 40 fork. Throughout the season the team has been swapping between the 325lb and 350lb spring, trying to get the right set up for each race.  While swapping springs they’ve also been trying out an off-set 6mm headset — the team ran a standard headset on arrival in Val Di Sole, but as of Friday practice the spring is still being swapped between the two.

Tahnée likes a poppy front-end and is running the fork relatively hard for her weight (we were too polite to ask), at 55psi. Four volume spacers are in there to keep the front-end height consistent on the steep track here (and Vallnord last weekend). This is run with a slightly softer back end, again keeping a height bias towards the front. Complementing this is the position of the geometry chips, which are set with a low-slung bias.

Tahnée’s tyre sponsor is Schwalbe, so it’s little surprise to see ProCore stickers adorning her wheels. The practice set of wheels here look like standard tubeless in the front, but ProCore is definitely present at the back. The team has been playing with the pressure in the ProCore system in order to balance feel and performance. Too much pressure can feel a bit pingy, but too low and you lose the rim and tyre protection — it’s a balancing act all the ProCore teams will be playing.

Run alongside the ProCore is a First Ride Magic Mary tyre. This is Schwalbe’s prototype line, with this tyre designed specifically for the ProCore system. The sidewall is thinner, and hence lighter, with the ProCore offering the puncture protection lost by the thinner sidewall tyre. A standard Magic Mary is run up front.
