Made from super lightweight high strength forgeable 7075 T7X alloy, the extremely low and first of its kind Syntace FlatForce stem made of a completely hollow construction weighs just 116g in a 66mm length. The FlatForce can be combined with bars of up to 800mm width, yet still providing a stiffness and strength usually found in stems of over 200g. The low 3:5 boom tube has a less than 25mm build height for the the most effective knee, back and chest protection.

The Sabertooth-Design is newly developed and patent pending bar clamping mechanism: nothing protrudes, no bolt, clamps nothing. But on the bottom the stiffness optimised Sabertooth jaw holds the bar with 100% reliability and leadership quality. With a special 200° head which makes the best “bed” for your handlebar, by reducing bar flex you’ll get increased handlebar strength, fatigue life and further improved steering precision at minimal weight.

Syntace Syntace Flatforce Stem 5 5 5 5

Excellent stem Two minor niggles: (1) The finish is a tiny bit less robust than the black finish on leading competitors (2) These stems are measured different than others, for example an 88mm stem puts the bars at the same reach as a regular 100mm -17° stem, but almost an inch lower. Normal stems are measures centre-to-centre, these are measured as distance from the steering axis, which for negative angle stems is substantially shorter... Need to be careful to study drawings and compare with conventional stems. That said, it's brilliant! Incredibly lightweight and rigid, the best option by far for dropping bars lower on many bikes, road or MTB.. ..I use them for both. The 27mm stack height, compared with normal 38-40mm, is only part of the story. A regular -17° stem has a horizontal beam with an offset of 5-6mm above the centre of the steerer clamp, to clear the headset. The horizontal beam on this stem is shallower and is centred about 11mm lower than a normal stem. Then there's the bar clamp, which drops the bars another 11mm below the beam. Result, about 22mm lower bars. 03 September 2016

Maximum slammage This stem drops you at the right angle for those steep climbs and brings you back to that race position. Very good aesthetically too. I love how simple yet helpful it can be. 16 February 2016

Good looks, superb quality, ideal for 29ers This stem gives a massive drop to the bars so works brilliantly for 29ers especially with longer front suspension. I have used it on my light weight builds (at 110g it is not too bad weight wise ) Syntace parts are always impeccably made and this is no exception, decent bolts and unique offset bar clamp and the only stem to really offer the level of drop needed on long travel 29er bikes. A bit pricey (again all relative as seems good value to me against £200 stems I am looking at) 20 March 2015

building up a new Niner EMD9 this stem gives me the same low bar position I had with my 26 inch wheel bike. The 29'r has a higher front profile and this stem with its low negative degree angle and the stem body shape lowering the bar position lower again, give a great range of positions for 29'rs or even a slammed position on a road bike.. The only small hesitation I had when buy this would be the cost but the build quality and the design giving the lower bar position I feel would be balanced out. Great solid stem, would recommend to anybody. 04 February 2015

Stem angle

Do these stems have a 73° (-17°) angle? I'm looking for something that will have zero rise.

Answer:

yes the stem appears to give an overall flat (zero rise) but with the bar position being dropped beneath the center line of the stem it works out to be about a -24 degree stem

Answer:

I don't think it's that simple. The lower handlebar position has two effects, it brings the grips closer to the steering axis affecting feel and it brings the bars back towards you compare to a horizontal (e.g. - 17 degree) stem of the same length . For either of these reasons you may end up wanting 0-10-20mm longer in the Flat Force than a regular stem. Best check it out somehow first. I set up a genetic juzzi upside-down to play around with first and mimic what I'll eventually buy. The juzzi is heavy, not very rigid, and will have tall bits sticking up, but it let's you check out any stem option.

Answer:

The 77mm stem is the closest length to the 80mm you require. They also make an 88mm length.

Answer:

Unfortunately we don't offer these in a 80mm length, the closest length we have to that would be the 77mm. My apologies for the inconvenience caused.

Answer:

I would suggest the product linked to this post will provide a better option for your P3. It has two negative degree angle options available to help achieve a lower position.
