Zipp’s pro-proven line of Service Course and Service Course SL stems and seatposts has been completely redesigned for 2015, providing more options for better fit and claimed best-in-class stiffness-to-weight ratios.
Zipp’s new lineup of stems and seatposts follows the redesign of their Service Course and Service Course SL handlebars. With stems in 7 different sizes and 2 different rise angles, getting your fit right becomes a lot easier. All these options should mean you’re more comfortable and efficient on the bike while riding.
Pro cyclists have ridden Service Course products with great success at Grand Tours, Spring Classics and top cyclo-cross races. Zipp has worked closely with these pros to get their feedback. They have also studied manufacturing techniques, material choices and the latest in rider fit needs. One interesting deviation from the norm is the use of Torx bolts. Zipp think these are better than the usual Allen bolt, being less likely to round out if over-tightened. A T25 tool is included with all stems.
The new design is a subtle black, so you won’t have any problems matching Service Course and Service Course SL components to your bike, very important when sitting at the cafe stop!
The Service Course SL stem and seatpost are available in two color schemes: High-polished Black with silver laser-etched graphics or Beyond Black anodized with black graphics
The Service Course SL OS stem is an all new stem that fits 1-1/4 inch steerer tubes. For bikes with 1-1/8 inch steerer tubes Zipp have included shims that will allow the stem to be adjusted for ±4° ±6° or ±8° angles. Available in 70, 80, 90, 100, 110, 120, 130 mm lengths – a 100mm stem weighs in at 140g and will cost you around $130/€112/£96 when it hits the shops this March.
The Service Course SL stem has a redesigned shape and comes in 7 lengths, like the SL OS and is available in ±6° and ±17° angles. The SL shaves 15g off the SL OS and will set you back $110/€103/£88 when it arrives in store this February.
The Service Course SL seatpost’s shaft and head are 3D-forged from a single piece of 7075 aluminum. Titanium bolts and more intricate machining save a little weight over the Service Course version.
Service Course SL seatpost comes in 27.2 or 31.6mm diameters and in two setbacks to allow for better fit, either 0mm (220g) or 20mm (235g). Priced at $115/€97/£83, it will be available in February.
The Service Course range while cheaper than the Service Course SL, still has the same options and manufacturing techniques, so you may carry a few grams more, but your wallet will be a lot happier. The colour scheme for the Service Course range is Bead-blast Black with laser-etched graphics.
The Service Course stem comes in 7 lengths for the ±6° and 4 lengths in the ±25° version, weight for a 100mm stem is 150g. Priced at a wallet pleasing $55/€52/£44 and available from February.
Available in 27.2 or 31.6mm diameters, the Service Course seatpost fits all common saddle rail types. At 245g for the 0mm offset and 270g for the 20mm offset, you aren’t carrying a lot more weight and they will be available from February at $55/€47/£40.
