27.5” – RM650BC14 – 50mm Carbon Rim

27.5” – RM650BC14 – 50mm Carbon Rim

Our ultralight plus rims are just 450g which is impressive considering their massive 45mm internal width! Typically, stock alloy plus rims use heavier spokes to make up for their lack of stiffness which adds a significant amount of weight.

Upgrading to our plus rim can easily save more than a pound off of a stock wheelset, that’s a lot of rotational weight! Breathe new life into your ride and bring a new level of responsiveness and control.

For those looking for something a bit narrower or for heavier duty plus riding, please check out our AM740 rims.

Please note that the price is per rim. We stock rims in UD Matte and a 32h hole count.

Special orders for custom hole drilling and finish can be ordered below.
