Zipp has two new water bottle cages in its range – the 18g SL Speed and 27g Alumina. Both will be available this month, with the carbon SL Speed costing US$75/€68 and the aluminum Alumina going for US$35/€32 (UK prices TBC).
Aside from its feathery weight, the Zipp SL Speed is notable for its flexible design; the thin arms pivot for easier easier bottle access on compact frames. Zipp claims the design is still quite secure in retaining bottles over rough roads.
The Alumina cage shares a similar design but with a bit less flex. At 27g it's still quite light, and quite a bit more affordable than the SL Speed.
