Anyone using this stem? Is its length true to spec (as it's not uncommon to have up to +5mm more than the specificed length)? Can it be mounted both +/- 8-deg? The official specs only states +8-deg. Quality and stiffness report? Thanks!

Search for the fairwheel bikes stem test. Fairly extensive review and comparison of that and other stems.

I have a -8, 110mm version. You can mount it anyway you want. Stiffness, compared to what?
I don't use mine since i moved to a -10, 120mm stem.

I love these stems and have a 110 & 120mm. Stiffness is much better than the Extralite and McFK stems I run on different setups. Not a weight weenie stem but very well made and the Tune outfront Garmin mount is the best in the business. Not sure why you’d want to run +8 as it would look super awkward?

MTB world want to run it at +8.....that is who it was really intended for as the clamp is better designed that way up.

Who told you that?

I seriously doubt Tune has designed a stem to be used +8 angle. Or would you think the -17 stem is designed to be +17?

Tune are a predominantly MTB co.........
If you look at the stem closely you will see that in the positive orientation the top of the clamp is much more, rounded off when run negatively the top looks aesthetically awkward. I’m not saying you can’t run it negatively but I think it was designed foremostly as an MTB stem .....the fact that the steerer clamp bolts are mounted on the left side when the stem is run negatively also points to this.....

You’re 100% correct- here is a pic of my 120mm 8 degree:

The machining around the steerer is much more rounded on the underside and much sharper on the top. Definitely indicative of initially being designed for +ve rise use. The MTB guy is an obvious giveaway :lol:
