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…
