The Spindrift runs 180 mm front and rear — Propain's freeride / super-enduro travel bracket. The Tyee is 170 mm front, 160 mm rear — a modern long-travel enduro spec.

That 20 mm of front and rear travel changes the bike's character far more than the number suggests. The Spindrift swallows DH-bike-sized hits and feels planted at speed; the Tyee is more responsive at the bar, easier to manual, and quicker to change direction in tight terrain.

Both climb genuinely well for their travel — Propain's PRO10 suspension runs high anti-squat (around 100–120% at sag on both bikes), which means very little pedal bob and a firm platform when you push on the cranks. Pinkbike's reviewer said they 'never once used the climb switch' on the Spindrift; MBR called the same bike 'exceptionally efficient pedalling for 180 mm.'

If you're splitting hairs: the Tyee is the lighter, more nimble climber — less bike to drag uphill and more responsive when you stomp. The Spindrift rewards smooth cadence; if you keep it pinned, it climbs anything, but it doesn't love stop-start technical pitches.

For most riders at most parks, yes. The Tyee in its slack flip-chip setting (62.8 degree head angle) with a 170 mm fork and a coil shock is a serious gravity bike — TheLoamWolf called the coil-shock setup 'an aggressive rocket ship' delivering 'downhill-bike levels of control.'

The Spindrift starts to pull away when the features get truly big — sustained Whistler-grade A-line, cliff drops, mandatory hucks. That's where the extra 20 mm of travel and the dual-crown option on the alloy frame matter.

It matters more on the Tyee, where reviewers consistently describe two distinct ride characters depending on shock choice: air gives you a lively, poppy bike; coil turns it into a plush, traction-rich plow. You can effectively tune what kind of enduro bike you want.

The Spindrift is more consistent across shock choice because its travel and progression curve already deliver a very plush mid-stroke regardless. Most stock builds ship with whatever Propain's configurator default is for that price tier.

Propain doesn't sell through bike shops in most markets — you order online through their Build to Order configurator, pick from a wide menu of forks, shocks, drivetrains, brakes, wheels, dropper lengths, and even decal colors, and they ship the assembled bike to you.

Upsides: real customization at order time, and prices that undercut equivalent dealer-network builds. Downsides: no local demo, limited service network outside Germany, and you're committing to a fit and color choice without sitting on the bike. Propain North America has a reputation for solid post-sale support per owner reports, but it's not the same as walking into a Trek shop.

Spindrift M: 460 mm reach, 627 mm stack, 63.5 degree head tube angle, 78 degree seat tube angle, 1,254 mm wheelbase, 445 mm chainstays.

Tyee M (29 in, slack flip-chip): 439 mm reach, 633 mm stack, 62.8 degree head tube angle, 76.1 degree seat tube angle, 1,247 mm wheelbase, 445 mm chainstays.

Tyee M (29 in, steep flip-chip): 449 mm reach, 626 mm stack, 63.9 degree head tube angle, 76.9 degree seat tube angle, 1,237 mm wheelbase.

Net: the Spindrift is longer, taller, and steeper at the seat tube. The Tyee is more compact and gives you a flip-chip choice the Spindrift doesn't.

The Tyee is the one most reviewers point at. Its flip-chip lets you go slack and aggressive for race day, the coil-shock option turns it into a serious descender, and the climbing efficiency means you're not punished on long timed transfer stages.

The Spindrift is more of a freeride / super-enduro bike than a pure race tool — it's heavier, longer, and the 180 mm rear is overkill for most enduro courses. If your local series tilts toward Whistler-grade tracks, the Spindrift makes sense. For most EWS-style courses, Tyee.

Propain offers a frame warranty against manufacturing defects and a separate crash-replacement program through their North American office for damage from riding. Customer-service experience appears strong from owner reports — one Canadian owner cited proactively shipped replacement parts and follow-up checks a year after purchase.

That said, you don't have a local dealer to walk a frame into. Plan on doing your own bleeds and bearing services, or building a relationship with a shop willing to work on a bike they didn't sell.
