Quick Pro ER One Seatpost Yoke 22.5 g vs Stock 64.7 g (42.2 g Saved)

The Quick Pro ER One seatpost yoke — the saddle rail clamp assembly under the seatpost head — weighs 64.7 g in stock form. TiNE's titanium yoke set drops that to 22.5 g, saving 42.2 g at the highest point on the frame.

42.2 g removed from the saddle. The seatpost yoke sits directly under the saddle rails — the highest point on the bike. Weight here has disproportionate impact on how the frame feels when carried over barriers, climbed out of the saddle, or accelerated from a standing start. Removing 42.2 g from this position lowers the bike's effective center of gravity more noticeably than removing the same weight from a lower position like the chainring or derailleur.

The Quick Pro ER One uses an integrated alloy seatpost yoke that combines the saddle rail cradle, base plate, and clamping hardware into a single cast piece — weighing 64.7 g. That makes it the third-heaviest stock yoke in TiNE's compatibility range, behind Colnago at 83.1 g and Colnago Y1RS/V5RS at 66 g. The 42.2 g savings is significant: more than Pinarello's 32.3~37.9 g, though less than Colnago's 62.8 g.

What the TiNE Quick Pro ER One Yoke Set Includes

Three components replace the entire stock clamp assembly:

2 titanium screws — Grade 5 Ti-6Al-4V, CNC-machined, handling saddle rail clamping force. Titanium resists corrosion far better than the stock steel bolts in the saddle zone — a high-splash area exposed to sweat and road spray.

1 carbon fiber base plate — replaces the heavy alloy casting, lighter and structurally stiff. The carbon layup is specific to Quick Pro ER One seatpost head geometry.

2 7075 aluminum yoke arms — CNC-shaped to match the Quick Pro ER One seatpost head profile. Not shared with other TiNE yoke versions.

Quick Pro ER One Compatibility

The TiNE yoke set is designed for:

Quick Pro ER One (stock yoke 64.7 g) — TiNE saves 42.2 g.

Quick Pro ER One seatpost designs vary across model years. Confirm your stock yoke weight before ordering — if your Quick Pro ER One uses a different yoke assembly than the 64.7 g version, the TiNE yoke set may not fit. The two-piece carbon base + 7075 aluminum arm design is specific to the ER One seatpost head shape.

TiNE Yoke Sets — Full Lineup Comparison

The Quick Pro ER One yoke delivers the fourth-largest savings among TiNE's eight yoke versions — behind Colnago (62.8 g), Y1RS/V5RS (45.2 g), and ahead of Cervelo S5 (40.4 g). For Quick Pro ER One riders, this is the single highest-ROI titanium upgrade available on the bike: more grams saved per dollar than any bolt, cap, or screw replacement.
