DROP BEST UC F21

SAFE.
High strength 7075 aluminum throughout. Strongest, 12.9 grade, US made fasteners. Swiss coatings for corrosion resistance.

EASY.
Totally independent angle and saddle position adjustment makes installation a childs game.

ADJUSTABLE.
Keep or raise your post’s stack height with the included spacers. Or use them to achieve extreme saddle angles (some riders are into that :) See a detailed compatibility chart here.

COMPATIBLE WITH ALL POSTS USING THE MY2021 FOX TRANSFER HEAD DESIGN.
Compatible with every dropper using the MY2021 Fox Transfer head design. Without adding stack height. And in forward or rearward offset use. And for most seat tube and saddle angles. See a list of possible settings here. If you are still unsure about the fit on your post, you can even download and 3D print a dummie to physically thest the fit here. DROP BEST UC F21 is compatible with all saddle rails: 7 mm round, 7x9 mm oval and 7x10 mm oval. No extra parts needed!

MODULAR.
DROP BEST UC F21 is fully modular: Beyond the adjustability via its five spacers, you can make your DROP BEST UC F21 work on almost all seatposts with vertical clamping bolts, just by purchasing an additional hardware kit: For posts using M6 bolts, M5 bolts and for proprietary posts using one bolt installed upside down (e.g. many high end carbon road bikes/posts) and Fox Transfer 2025/Transfer NEO wireless posts too.

LIGHTWEIGHT/HEAVYWEIGHT.
At 159g, the DROP BEST UC F21 assembly weighs 69g more than the original Transfer MY2021 saddle clamp. That's heavier. But at the top of the one hour gravel grind, your thanks-to-the-DROP-BEST-UC correct seating position will make your bike feel much lighter.

PRECISION.
Precision machined in Switzerland. High end coatings throughout.
