While Americans where attempting to sleep, Trek World Racing’s Brook Macdonald was getting ready to race the New Zealand National Championships. His secret weapon? A beautiful new paint job that partially masks the contours of his prototype 650b Trek Session.

It’s hard to tell was kind of special trickery the engineers at Trek have employed on this new bike, but the frame looks a little leaner than Ye ol’ Session, and the front triangle has a decidedly carbon look to it.

That seat/top tube junction looks similar to the Top Fuel carbon models that were out a few years ago.

29er Enduros are the new 26/27.5 downhill rigs.

This was inevitable. 650b makes a lot of sense for DH.

The rear shock is a prototype RAD inspired shock. The piggyback unit is shorter, someone posted about it on another website.

What rear shock is that? Looks like it could be a proto Cane Creek or TTX ohlins.

Looks more like the fox rad, the ohlins is more gold and yellow

Really dont think that is carbon. Looks more like hydroformed and heavily painted alu.

650b DH bikes make sense for taller riders just as 29″ wheels do for AM/Trail.

If this is a prototype then it likely isn’t carbon unless it’s very close to production (when you consider the costs to tool up for carbon production).

That or it’s a stock Sessions front triangle (or near-production prototype 26″ front triangle) and they’ve done their mods to fit the 650b rear wheel to the alloy rear end.

Either way Trek let me know when this will be available in an adult-sized XL and I’ll put down a deposit.
