HANDLEBAR STEM HEADSPACE 31.8

$100.00

Retro-inspired, modern functionality.

When we set out to design a stem, we knew the market already had some great options and probably didn’t need another lightweight or round stem to add into the mix.

Looking at some of the great designs from the early days of MTB, we wanted to add some of that styling into a modern version.

Updated now to a 31.8mm bar diameter and available in 1 extension – 70mm – our new HEADSPACE stem offers a new option to the crowded stem market.

Why 70mm? Well, with gravel bike geometry progressing almost daily and most modern 29er trail setups running shorter stems ( less than 90mm at least ) we think this is the sweet-spot.

  • 70mm Extension
  • Zero Degree Rise
  • 31.8mm Bar Diameter
  • Forged Alloy Construction with CNC-Machined Finish
  • 70mm Clamping Width ( ideal for Drop Handlebars and Flat or Low Riser MTB Handlebars )
  • Final Weight : 179g

Please see our PRODUCT INFO SHEET for important details about clamping width and handlebar compatibility.

We designed the Top Clamp to be the same width as our Carbon/Alloy Aero Bolt-On and therefore allow for a unique and completely integrated front-end setup. Please see the gallery for some images of how the system looks.

FAQ

Q : What is the Rise on the Stem?
A :  The stem features a ZERO Degree Rise. Once installed on the steerer tube of most modern bikes, which are all going longer/slacker , the need to have any rise on the stem ( most are only around 6 degrees anyway ) seemed pointless. Also with the varied use in terms of handlebars ( Drop or MTB ) the options to get the right setup are endless.

Q : Is the stem strong enough for MTB use?
A : Yes, definitely! We tested our first prototypes for EN MTB standard and it passed with flying colors. The stem was so stiff we even went and revised some of the CNC machining to allow further weight reduction. 

Q : How do I fit my GPS?
A : The inclusion of the Front Brace does effect the ability to clamp a GPS mount around the base of the handlebar. However, we have seen many riders run the Headset/Steerer Style mount on their bikes and this would be the best option for now. We are however working on some new accessories that will solve this problem … Furthermore with the stem allowing the fitment of both a Aero Bolt-On or an Aero Gravel handlebar, the mounting area/options increase with either of those additions.

Q : What MTB Handlebar will work well with this stem?
A : Ideally we would like to propose our Supa-Moto Riser handlebar as it has a wider and flatter center section allowing for this kind of stem as well as other accessories to be mounted in a neat and aesthetically pleasing way. Having said that, any handlebar that has a +70mm Flat 31.8mm section should work well with this stem. Flat/Low-Rise Handlebars would be the most compatible. 

Q : What Gravel Handlebar will work well with this stem?
A : Again, our Aero Gravel and Supa-Wide are great options, BUT we understand you want options. Basically any round 31.8mm style Drop/Gravel handlebar will work. Some of those funky / oval shape bars will probably not work well this stem. 

Q : Will you be offering other extensions in the future?
A : Yes…but not until we have seen the response and sales for this 70mm version.
