Input from freeride legend makes the TMACs some of the best flats on the market

This competition is now closed

Deity’s TMAC flat pedals have been designed with input from legendary freerider Tyler McCaul and are claimed to be the brand’s largest pedal to date.

They boast a super-concave profile and a 6061 T6 aluminium body.

They’re available in a wide range of anodised colours, too.

Measuring 110(L)x105(W)mm at its widest points, the TMAC’s platform area is large and square.

Their front and back edges have a symmetrical rather than chamfered asymmetrical shape that’s claimed to improve stability and measure 17mm deep.

At the pedal’s central axle bulge over the chromoly steel axle, they are 14mm deep giving a concave profile.

They have 14 grub screw-style pins per side placed around the platform’s perimeter, and each pin is adjustable and replaceable.

A spare set of pins is included with the pedals. The pins can be screwed deeper into the pedal to adjust their height, but we settled with 4mm of external pin showing, leaving 4mm of pin threaded into the pedal body.

They spin on a bearing and DU bushing setup. Our test sample weighed 454g.

The location and number of pins is a formidable combination, where traction is unparalleled resulting in no foot twisting or movement or instability, even over massively rough terrain.

The concavity of the platform boosts traction further, placing our foot’s pressure exclusively on the pedal’s edges where the pins are.

The concave profile cupped our feet exceptionally well, too. The large platform means there’s plenty of margin for error of foot placement, where we didn’t feel like our feet were teetering over the platform’s edges compared to smaller competitors.

Foot clawing was virtually non-existent, reducing fatigue and improving control.

The lack of edge chamfering meant rock or ground strikes felt harsh, but our feet never got blown off the pedals thanks to the immense grip on offer.

The top-loading pins – if damaged – can be removed from underneath if the opposite side’s pin is removed first.

During testing we snapped one of the pins in an almighty hit with an immovable rock, but replacement was quick and painless, and the pedal’s body and axle remained unscathed.

Plus the included replacement pins meant we didn’t need to source our own.

We’ve tested 13 flat pedals for mountain bikes in some of the harshest conditions on a host of terrain types – from bumpy on-the-gas sections through to flat-out rough and worn downhill tracks – to see how much grip they offer and help you find the perfect companion.

Tyler McCaul’s signature pedals boast fantastic grip, impressive robustness and a large well-shaped platform that provides plenty of stability.

They just edge ahead of the Crankbrothers Stamp 7 thanks to their totally concave platform, and once testing finished these are the pedals we’ve continued to use in our free time.

They are truly worth their asking price.
