Funn RSX Stem

Our review

Stiff-as-you-want downhill stem with a low price tag
Skip to view product specifications

The RSX stem is designed to be bolted directly onto the top crown of RockShox Boxxer downhill forks and is fully CNC machined from 6061-T6 alloy.

The stem features a 30-degree rise and can be run at either 45mm or 50mm reach. Funn makes a similar stem (the MZX) to fit Marzocchi’s 888 downhill forks.

Feel is super-stiff and by using titanium front-clamp bolts, the weight is kept down to a skimpy 185g. Subtract the grams you save by being able to chop down your steerer and the RSX makes a lot of sense.
