Renthal Apex 31mm Stem

Ultra short size to suit new-world bike geometry

We’re big fans of Renthal here at Dirt with this UK brand taking regular slots in the Dirt 100 with their Integra stem and carbon Fatbar. Here we take a look at their latest trail/enduro stem in a new stubby 31mm length.

The Apex stem was launched back in July 2014, and although it sits alongside their established (and much loved by us) Duo stem, it soon found a place on our trail and enduro bikes. That was over 18 months ago now, and in that short period we have seen some real changes in frame geometry and sizing and when this 31mm stem arrived its timing was spot on.

We’ve always run short stems on our bikes here at Dirt, with 50mm lengths being fitted in place of the overly long stock choices we often find, even in 2016. With the bigger 27.5″ and 29″ wheels we found that going shorter still, got the handling dialled and added even more stability. Riders have also been up-sizing, getting more reach in the frame itself and then adding as short a stem as possible.

The Easton Havoc and Hope AM stem with a 35mm length have been a good choice for a while, but with Mondraker’s ‘Forward Geometry’ and the UK designed Mojo Nicolai Geometron stretching things further, there is a need for shorter without adding height.

Last autumn the Pacenti P-Dent bar and stem system arrived, a unique stystem that addresses this issue well. You are however buying a stem and carbon bar together when you may not need to buy both.


“The Apex stem hit our scales at 105g, but retains the Renthal hallmarks of stiffness and strength”


Renthal have delivered a regular stem with a 31.8 bar clamp yet a 31mm length. You can keep the bar you have and go super short with no compromises we can find. The Apex stem hit our scales at 105g, this low weight would have the XC racers getting over excited, but retains the Renthal hallmarks of stiffness and strength With a steerer clamp stack height of only 40mm you can keep the front end low as well as short and held securely with offset pinch bolts.The two front clamps wrap 240 degrees of the bar adding to the reassuringly solid cockpit as well as reducing stress and keeping weight low.

With a realistic price for a superbly finished stem, made right here in the UK, we feel the timing is right for Renthal. If you are up-sizing to a larger frame, or looking to get the most from a big wheeler, then put this dinky Apex stem on your list.
