A single-bolt seatpost wedge uses a T25 torx head. That's a bit out of the ordinary, but at least it's the same size Zipp is using for all their Torx stem bolts. Looks like riders need one more tool in the saddle bag.
It's been a very long time since Orbea launched a TT bike. The Spain-based brand has had some struggles, both public and private, but has regrouped and launched a bike that belongs squarely with the rest of the next-generation tri bikes of their competitors. TriRig was present at the launch in Denver, Colorado, at the USA Pro Cycling Challenge during the Stage 7 Time Trial.
