Alugear AERO Chainring - MTB | 4x BCD 104 | 1-speed | Narrow/Wide | for SRM Powermeter Cranks - round | black

Technologically solid, extremely light and unique in design. These properties characterize the chainrings from Alugear. And the AERO chainring for MTB Powermeter cranks from SRM is no exception.

The CNC-milled aluminium chainring is characterized by good self-cleaning properties in muddy conditions and smooth chain running. This is due not least to the Narrow/Wide tooth profile, which keeps the chain securely in position at all times. Visually, the chainring stands out with the AERO look typical of Alugear. To maintain this look for a long time, the chainring has an industrial hard anodization, which noticeably increases the protective effect against mechanical impacts. The unique tooth profile also contributes to increased wear resistance. In addition, it eliminates chain noise to ensure smooth operation of the entire system.
