Zipp has just announced an all-new collection of Service Course stems and seatposts, with both technical refinements and more fit options. The changes spread across both the standard and SL levels and carry with them fresh graphics, too.
For the stems, shapes are refined from prior models, and it’s more than just aesthetics. They claim small improvements in both stiffness-to-weight ratios and overall weight. Also, MSRP prices are a bit lower, too, helping fit them onto more bikes and into more budgets.
Above, the new Service Course SL OS comes with an oversized steerer tube clamp section for 1-1/4″ steerers. That gives Giant and Canyon bike owners another cockpit option, but it also gives the majority of riders more angle options to fine tune their fit. On the 1-1/4″ steerer it’s fixed at +/- 6º. But, using the included shims and adapters, anyone with a normal 1-1/8″ steerer can now get +/- 4º, 6º or 8º angles.
UPDATED: Comparison to 2014 models added and small corrections made.
But that’s not the only new option…
On the standard Service Course stem, you’ll get a new +/-25º stem to go along with the usual 6º option. Slam that stem and achieve a whole new low, and it even gets a new 60mm length on all standard versions to accommodate the shortest of riders.
The SL models have 6º and 17º options, same as before.
The SL series gets two color options: gloss black with white logos or matte black with black logos. The standard series gets this bead blasted black with laser etched graphics. All will match up with their corresponding handlebars.
On a few items, the actual weight goes up a bit compared to the 2014 version, but the stiffness to weight ratio improves. And they’re still respectably light. For most items, though, the overall weight goes down. And the prices all go down, in some cases to almost half!
Seatposts are redesigned to enable better bolt access, making saddle installation and adjustments easier. The SL shown on left in 27.2 with 20mm offset, all others are standard Service Course, from left to right: 27.2/0mm, 27.2/20mm, 31.6/0mm and 31.6/20mm.
