100% roller bearings and nothing else
Understanding and using the laws of physics: roller bearings have a much lower coefficient of friction than friction bearings, especially under load. This becomes even more evident when radial friction bushings inherent in the design of friction bearings become contaminated with the grit of everyday use. This is why we use only the finest precision cartridge bearings at all three bearing locations. Simply put, for you as a rider, this means: you have pedals with the least possible power loss. The harder you pedal, the greater the performance output advantage.
If you build strong, you can build light weight.
The lightest fully ball bearing equipped pedal: Machined from one piece of 7075 T6 aluminium instead of the so often used and easily anodised 6061 aluminium. By the way the 6061 aluminium can also be recognised without a materials lab, simply by the variety of bright colours on offer. In contrast, high strength alloys always show a slight colour influence by their specific naturally occurring alloying elements. This will vary the appearance of each individual pedal as can be seen with the silver-grey finished of the NumberNine Titan pedal. All ribs and cross members are explicitly designed as structural load bearing members without any cut-outs or holes or other similar fashionable attributes. A modified and improved body profile allows the use of a hollow, high strength Titanium axle. High load axial impacts are absorbed by an especially tough end-stop instead of by the bearings.
The result: sensationally light at 288g (size M incl. 56 pins) … and rated at over 500kg ultimate load per pedal!
Supergrip with I.S.C.
The Syntace “Improved Surface Concept” is no newly developed concept for improving the shoe to pedal connection, much rather a fine tuned concept resulting from a tedious and lengthy pedal shoe contact detail analysis comprising of 5 components:
1. The 56 pins are carefully placed on a special, slightly concave, elevation profile: the middle 6 pins are placed slightly lower, the outer eight pins are placed on elevated and continuous cross members without any cut outs.
2. Instead of just simply making a “hammock” style hang-through centre surface (concave), the NumberNine Titan has 6 (!) centre pins which are additionally slightly recessed. When the weight of the foot is slightly lifted, these pins, due to the relative proximity to the rotational centre of the shoe, allow a softer rotation commencement and more controllable movement of the foot than the outer pins can provide. Just like a good tyre with wide and easily controllable borderline instead of an uncontrollable break-loose point. Under high pedal pressure however, the I.S.C. pin positioning shows a different face: now a highly twist and slip free connection between pedal and shoe shines as the pins can now grip where the greatest force is applied, directly above the axle.
3) Visually not instantly recognised: The two large NumberNine windows allow for the soles of the shoe to slightly bend into each of the two large pedal openings. In critical moments, this “camel’s hump” profile creates a more effective interlocking than the standard singular concave form of the pedal surface. And this, without even increasing the pedals thickness by one millimetre.
4) The hexagonal collared pins with low but sharp edge, combined with cylindrical 2.8mm threadless centre profile provides for perfect force transmission with the new, softer, grip-optimised shoe soles. Much better force transmission is achieved than with for e.g. the “legendary” thin grup screw where contact area to the shoe sole is reduced by the thread grooves.
5) The Syntace “Butterfly”-body with the four wide drawn pedal corners allows for best contact
of your shoe with the critical outer corner vicinities in extreme angular positions of the foot.
These five components of the Syntace Improved Surface Concept raise your security against unwanted slipping off the pedal, without compromising the ability to move the shoe on the pedal too much. Furthermore, the Syntace I.S.C. with 6 centre pins and 8 cross-member pins allows fine tuning by removing one, two or more pins creating a bandwidth of “light grip” to “stuck on”.
The NumberNine Titan is sold with one full set of 56 alloy 7075 T6 pins (incl. 5 spare pins), as well as a hex key driver with modified head for simple assembly of the pins. You can not only vary the number of pins, but can also replace the more exposed pins with steel pins. The Syntace steel pins are available in a pack of 10 from your Syntace dealer.

Note: for assembly of the Syntace steel pins you will require a Loctite such as the Syntace Bond 48 medium strength (blue) or Loctite 243. The Syntace alloy pins are designed to be self-locking and can be assembled without a thread locker.
Only 15.4mm build height… even though cartridge precision ball bearings with a high safety margin are used all round. The advantages are obvious: A flat pedal allows a lower rider’s centre of gravity, as well as reducing the likelihood of clipping obstacles. Despite the low build height and at the same time large pedal face profile, additional cross members are not needed to maintain the desired strength properties and allow the unmatched self-cleaning properties of the predecessor to be maintained.
Purpose built high strength 7075 T6 alloy pins that are significantly stronger than conventional alloy pins, and featuring a strong pre-defined breaking point. The Syntace flat collar pin design always allows a trouble free pin removal if worn or even damaged without damaging the thread.
The slim and aggressive 5mm hexagonal collar shape, as already mentioned, provides perfect “toothwork” for best interlocking grip especially with soft soled shoes. As an important force transmitting element it’s height is to be added to the effective length of the pins shaft. This is why, the Syntace pin lengths are stated not only with the extending shaft length (here 3mm) but with the full length of 4.2mm.
The right pedal size for every rider
The Syntace NumberNine is the first pedal, which is not only available in one standard size, but in three proportionally scaled sizes. Because, a pedal should not fit a standard sized rider, but actually fit you. As a rough guide you can go by:
35 - 42
38 - 45
43 - 50
Next to the shoe size, the optimal pedal size will vary depending on the actual sole width of your chosen riding shoe, your personal positioning on the pedal and the type of riding you do. The exact sizes of the relative pedal faces you can find

No loopholes for moisture and dirt
Apart from the axle exit point, the Syntace NumberNine Titan pedal is air and moisture tight all round. The pedal body rotates completely closed around the outer axle end, the point which is most susceptible to moisture, grit and dirt. A location, at which multiple friction bearing pedal manufacturers have not even made a serious attempt at sealing the pedal properly or sometimes even leave the axle to rotate completely exposed. What several manufacturers promote as double sealed at this point, is, when looked at properly, in fact two unsealed axial washers with slits inviting contaminating dirt. With the Syntace NumberNine Titan however, the only required seal is a distinctive red coloured radial precision shaft seal, especially developed by Syntace and positioned on the inside in front of the axle thread.
Thanks to the shape of the pedal body which comes close to the crank arm the seal is nicely nested inside the pedal body where it is protected by the crank arm.
Always nicely horizontal
The Syntace bearing design slows the free spinning motion without load just enough so that when you lift your feet off the pedals, the pedals remain in their position, and are right there for you to place your foot back on the pedal in the same position. The “little helper” has neither noticeable nor measurable adverse effects on normal pedalling as it is not in line with the load force (see “100% roller bearings, and nothing else”).
