Our Verdict

The Deity TMAC is Tyler McCaul's signature pedal, designed to meet the demands of one of the most versatile mountain bike riders on the planet. The TMAC is a beautiful blend of thoughtful engineering and exquisite looks. These symmetrically designed pedals are extruded and machined from T6 Aluminum for strength and durability. They offer excellent balance, a large platform, and tenacious grip with 14 pins per side. Their 2.5mm concave depth enhances grip and foot comfort while climbing and descending. The shape delivers a balanced feel and helps distribute weight evenly across the platform. These big and burly pedals are our top pick for gravity-fueled riding.

Our Analysis and Test Results

With over two years of R&D put into the TMAC's design, Deity developed what they refer to as "Your Dream Pedal." The pedal has a simplistic symmetrical design and square/blocky shape that makes the pedal appear more substantial in size than their 110mm x 105mm dimensions suggest. Machined from durable aluminum and fitted with high-quality components, these pedals have phenomenal grip with 14 pins per side. We loved these beefy pedals and we feel they are an excellent option for downhill and aggressive enduro riding.

Performance Comparison


The TMAC pedals have impressive amounts of grip. The 14 pins per side, lots of perimeter pin locations, and 2.5mm concavity combine to make your foot feel secure to the pedal. These pedals have so much grip that it's occasionally challenging to reposition your shoe while riding. This can be frustrating, especially when you're getting into a more technical section of a trail or about to hit a jump. There's nothing more annoying than that feeling of your foot being in the wrong position.

That said, the grip factor is so high with the TMAC that you can get away with riding with your foot in the wrong spot on the pedal for a section of trail. The one weakness we found concerning grip is the lack of pins in the middle of the pedal along the spindle. The smooth anodized spindle section feels slippery on our shoes with no pins, especially in wet riding conditions. It's natural for your feet to drift outwards as you ride and a center pin or two would help make your foot feel more secure and improve your grip in the event your footing becomes unsettled.

The TMAC pedals feature a large "block" platform that's 110mm x 105mm coupled with one of the most aggressive concave designs on the market at 2.5mm. The pedals have a non-offset, symmetrical, design and square/blocky shape that feels much larger than it is. Arguably, this is a double-edged sword; the large platform is great but also leaves a large open space in the middle of the pedal. It's noticeable when your foot isn't on the pedal correctly, and your contact point is in the open area of the pedal.

The pedal grips so well it makes it hard to reposition your foot in the middle of your descent. The more you ride these, the more you get used to this, but it is worthy of mention. The large size combined with the 19mm leading edge thickness does present more potential for pedal strikes and contact with other features on the trail. We didn't experience any strikes that caused a crash while testing, but we made plenty of pedal to rock contact. The most vulnerable spots for contact are the leading edge and the outside edges of the pedal. The thickness of these pedals does make them less ideal for trail riders, or those who frequent especially technical trails.

Here's the blunt truth, the TMAC grips so well that it can be challenging to move your feet at times. The openness of pedal design is noticeable, especially when climbing. The bearings work well and spin freely with no resistance. The pedals feature one of the deepest concave designs on the market, providing ample contact and control. Since the TMAC is one of the largest pedals we tested, the platform is plenty big to accommodate larger shoe sizes.

However, we found with smaller shoe sizes, the pedal's massive platform has an almost negative effect on allowing the riders foot to stay planted in one position. Due to the large open areas between the spindle and front and rear of the pedal, if the rider's foot were to move into these zones, it gave us the feeling of our shoes falling into a hole.

The Deity TMAC is well constructed, and this is visible across the board from its high-quality parts to its sleek machined design. They are easy on and off the cranks. If you're looking for a hassle-free, dynamite pedal, this may be the one for you.

The pedal's design takes into consideration load distribution while riding various terrain, and Deity has created a system to prevent bearing blowout. If a bearing blowout occurs while you're the owner of these work-horses, the rebuild kit won't set you back much at all. It's available for $24.99 directly through the Deity website and doubles as the same rebuild kit for the Deity Bladerunner.

They are far from the lightest pedals at 409g, but for their size, they hold their weight well. They offer great pedal traction and never felt out of touch with lighter pedals tested. The goal behind the TMAC was to deliver the largest platform available in the Deity pedal line up, and at the expense of little extra weight, they have created a pedal that feels much lighter than it looks. That said, the added heft and thicker profile make these pedals lies ideal for trail riding than some other options we tested.

You get what you pay for. The TMAC is not a cheap set of pedals but the attention to detail and years of testing behind them make these pedals a great value. Use them across many applications on multiple bikes, and in the event of a rebuild, $24.99 will have them feeling and looking fresh again.


Is bigger always better? The price could scare some consumers away, but the grip is amazing. Overall, the TMAC was one of the better pedals we tested. These pedals are very competitive against others in its class, and the combination of engineering, robust design, and sharp aesthetically pleasing looks make the TMAC one of our favorite flat pedals.
