- With their advanced one-piece 3D forged construction, these stems offer outstanding performance at an affordable price.
- This construction method uses 6061 aluminium allows for great weight saving without dramatically reducing the strength and stiffness.
- Wider bolt spacing at the bottom of the front clamp increases the strength of connection between the handlebar and stem.
- Available in 80mm x 40° and 90mm x 35°.
- 80mm x 40° offers the same amount of bar height as the 90mm x 35° stem, but with the reach of a 70mm x 35° stem! This makes it ideal if you want to have a slightly shorter reach to your bike, or ride a bike with a steeper head angle.
- Compatible with 31.8mm handlebars only.
- Available in anodized matt black with white logos.
- Supplied with Trialtech stickers enclosed.
- Clamp height: 50mm (80mm and 90mm)
- Weight - 90mm: 172g. 80mm: 147g.

Steerer clamp diameter: 1 1/8"
Bar clamp diameter: 31.8mm

Additional Information

Please ensure when fitting your new stem that there is a gap of 2-6mm between the top of your steerer tube and the top of your stem's clamping area. This will ensure that your headset can tighten correctly and give your stem good support from your forks.



Will this stem work with a thicker handlebar? i.e. a 31.8mm clamp area?

Hi Joe - this stem will work perfectly with 31.8mm clamp bars. Thanks, Flipp.


Hello, is this the stem Danny MacAskill uses on his Drop and Roll Tour?; here's a picture for example: http://news.bbcimg.co.uk/media/images/77790000/jpg/_77790043_77790039.jpg Is it the Trialtech Sport, 90mm x 35˚? And how would this fit my Inspired Arcade Handlebars and the old Inspired Skye Orange fork? Does stem rings follows if you buy the stem? Thanks, Johan

Hi Johan - thanks for your question. Yes, we're reasonably confident the stem in that picture is the 90mm x 35°. It will fit your forks and handlebars just fine. Thanks, Flipp.

When will the 90mm x 35° stem be back in stock, and if you're unsure could you e-mail me when it's available again, Thanks

Hi Gavin - thanks for your question. Our suppliers are out of stock so we cannot buy any more right now. It will likely be at least a couple of months before we can get any. We have a welded alternative available if it is the geometry you want: http://www.tartybikes.co.uk/product.php?product_id=10461 We have a system that will automatically send you emails about products coming back into stock if you ask it to. Just below the box with the geometry options and price details is a link saying "Contact me when back in stock." Click that, tick the box of the right stem and insert your email address and you will have a stock reminder set up. You can do this for any product. Hope that helps. Thanks, Flipp.

Will the 90mm fit an Onza RIP 20", I need to shorten the reach for my boy. Thanks

Hi Sharon - yes, that would fit your bike perfectly. Thanks, Flipp.


Hello, What is the advantages and disadvantages of a 80mm x 40˚ in a street 24 trial bikes.(especially in fourplay pro) Thanks

Posted by Kit on 27/02/2017

Reply from TartyBikes on 28/02/2017

Hi Kit - The 80mm x 40° stem is designed to be a middleground between the 90mm x 35° and 70mm x 35° stems that most riders run. The 80mm x 40° stem gives the bar height of the 90mm stem, but the shorter reach you'd associate with a 70mm stem. This works well for frames with steep head angles such as the Arcade, but on the Fourplay Pro both the 90mm and 80mm stems would work well. If you feel like you'd like to make your bike a little shorter (typically making it better for manuals, bunnyhops and spins) then you can put a shorter stem on, but if you'd like to help make it better for trials moves the longer 90mm stem will help. Thanks, Mark


What size bolts does this stem use?

Posted by Parkee on 11/08/2017

Reply from TartyBikes on 11/08/2017

Hi Parker - The different length and angle stems use slightly different bolts to each other. If you can let us know which stem in particular you're looking at, we'll do our best to help. Thanks, Mark

David Armstrong

Hi , looking to buy this stem but want to order some TI bolts at the same time what’s the bolt sizes on this stem (80mm stem ) so I can purchase at the same time cheers David

Posted by David Armstrong on 09/04/2018

Reply from TartyBikes on 10/04/2018

Hi David - For the steerer clamp you'd require M5x15 bolts, and M6x20 for the steerer bolts. Thanks, Mark

Looks sweet!

Really good stem! The shape is good and the geo is perfect. Im going for a stealthy look so the black bolts were a nice little extra! :)


lovely stem

Stem is very sleek, and made my bike a lot more comfortable to ride. Five stars.

Reply from TartyBikes on 05/09/2012

Hi Ash - Trialtech make a lot of stems, and all of them seem to be very good at what they do. Their forged models in particular! I'm glad it helped improve your ride, and thanks for the review.
