Renthal Strata Duo MTB Stem

Borrowing technology from our championship winning motocross technologies, we have designed and developed this stem to offer the ultimate combination of lightness, strength and durability. Renthal Strata Stems are designed to let you ride faster, jump further and last longer.

Renthal’s revolutionary Strata™ stem combines high strength with ultra low weight. The stem is horizontally divided down the centre which allows it to be CNC machined in two pieces. This method allows unrestricted access to the core of the stem which enables weight to be reduced to the absolute minimum without compromising strength.

In addition this provides an uninterrupted U shape clamping area, which eliminates the stress risers found on most other clamps which can lead to handlebar failure.

Renthal Strata Duo MTB Stem Features:

  • CNC Machined from 6082 T6 aluminium alloy.
  • Split stem design for maximum weight reduction.
  • U shape clamping area, eliminates traditional stress risers for the handlebar.
  • 139g (including bolts).
  • 31.8mm handlebar diameter.
  • 50mm offset/10° rise.

Rated 4.8 out of 5 by 17 reviewers.
Rated 5 out of 5 by one of the best stem out there certainly one of the best stem in the market and the quality and durability is outstanding. 14 October 2014
Rated 5 out of 5 by light and stiff Matched this stem with the Renthal carbon fat bar and am very impressed with both. I'm 95kgs and ride hard, technical trails and neither of these products have given an inch. As well as looking good and shaving some weight, Renthal gear is bulletproof. 23 September 2014
Rated 5 out of 5 by Stiff, well thought-out stem Great bit of kit; I wanted a shorter stem on my 160 bike for descending duties than the 60mm it came with. I looked at cheaper options but couldn't find the right length/style at anything like a worthwhile saving over the renthal. I've always like the look of these and the split clamp design is ingenious, the fact that it's light too is the icing on the cake. I wouldn't previously have thought the front end of the bike was flexy, but after fitting this.. Wow! Obviously the steering is a little faster (good) and my weight further back which is why I wanted this- but the big surprise is how much stiffer it seems. Gone is that rather sketchy feel in higher speed turns where you would feel the bike load up and then snap in another direction. 15 September 2014
Rated 5 out of 5 by easy to install for awesome rides! really easy to install, it is simply gorgeouse fitted with the renthall fat bar! 17 March 2014
Rated 5 out of 5 by Light, durable finish, follow the instructions eh! Before you fit this stem, RTFM, it needs to be torqued up in the correct order, do so and it's flawless. With a Carbon Fatbar it's a match made in heaven and I trimmed nearly 400gms off my front end. A perfect product, strong enough for charging DH, just don't expect it to survive unscathed from multiple bicycle cartwheels at warp speed, it's built to ride not crash. 14 March 2014
Rated 5 out of 5 by A really inovative design and stiff and lightweight I've had a duo stem 70mm for a few years now on a trek remedy 8 2012. It is lighter than traditional looking stems and just as stiff, if not more. It still looks great on the bike with none of the graphics lost. The biggest problem is during fitting. It is horrible to fit as the handlebar moves around and falls out. I did damage a bar because when it was tightened the bar moved the wrong was and when I forced it into the right position it scratched the paint off. I have fitted it twice and it was just as hard the second time. Luckily it is a fit and forget item, you won't be changing it round often. It the best stem I have tried but the price is high. 01 March 2014
Rated 2 out of 5 by Expensive, low strength stem Had nothing but issues with this stem. Would constantly creak which drove me crazy. Eventually had to tighten the bolts a touch more then recommended which ultimately cracked the stem around one of the front screws in front of the bar. There are better less expensive options out there. 21 January 2014
Rated 5 out of 5 by Excellent Only had one local ride to puddletown using it, but had put it through all different terrain and it suits me down to a T! Beautiful machinery! 14 January 2014

Answer: 
10 degree rise is the standard on this stem; as far as I know there isn't a 'without the 10-deg rise' option. It's a fab stem tho, brilliantly engineered & highly recommended, even if it's expensive!

Answer: 
This stem has a 40mm stack height so would require a minimum of 40mm free steerer protruding from the frame headtube.

Answer: 
Having just fitted one of these stems to a bike I'm currently building, I cam confirm that the height of the clamp stack is indeed 40mm. This stem itself is a very nice piece of engineering but the bolts supplied should be of better quality as standard. But it's a minor gripe, they do the job and can easily be upgraded.
