Two levels of Zipp’s Service Course line of bars, stems and seatposts are now available: Service Course and a lighter, SL version. The latter uses lighter fittings and a high-gloss anodised finish.

Bars

Available in two shapes, Classic and SS (compact), both models feature a 2° outsweep on the drops for a claimed ergonomic improvement. The £89.99 SL version uses a proprietary ZTL-71 butted, 20g-saving aluminium design to get to the stated 280g weight. The standard bar comes in at £74.99.

Stems

Using the same forged 7075 aluminium for both stems, the difference comes from the use of titanium bolts and a lighter faceplate. Torx bolts are used on both – improved reliability with torque settings being the reasoning. £69.99 and £89.99 gets you a stem to match the bar.

Seatposts

3D-forged from a single piece of 7075 aluminium, the head and shaft of the posts is constant across the £74.99 Service Course and £99.99 SL models. Extra machining of the low-profile clamp reduces weight on the SL variant, along with the use of titanium for the two adjustment bolts. 27.2 and 31.6mm diameter sizes are available this year, and with 275 or 350mm-length options, the lightest comes in at 220g.
