He may have missed out on the 10 mile time trial competition record, but we spotted Sir Bradley Wiggins using a new pedal

Continuing the hunt for marginal gains, World Time Trial Champion, Sir Bradley Wiggins was seen to be using a new Zero Aero Speedplay pedal at the City RC 10-mile time trial on Saturday. Wiggins is said to favour Speedplay pedals owing to past knee injuries he has suffered, with the Zero Aero pedals first unveiled in prototype form at Inter Bike 2014.

>>> How to set up your cleats

The Zero Aero differs from other Speedplay pedals, by being single sided. When the single sided pedal is clipped in, the dimples on the bottom create an aerodynamic profile that integrates with the cleat, which also features dimples.  The golf ball like pattern is designed to create a smooth surface for the wind that maximises aerodynamic efficiency.


Pink: The sock colour of choice for Sir Brad.

Here we can see how the cleat interfaces with the pedal, with Wiggins wearing his favoured Giro Empire shoes.

The 2012 Tour de France winner is due to attempt to break the Hour Record on the 7th June, where we’ll see if Wiggins uses the Zero Aero Speedplays, with aerodynamic shoe covers, often seen in road time trials not allowed in the velodrome.

    There are two things to this. In wind tunnel tests a few years ago the regular Speedplay pedal proved to have an aerodynamic advantage by having a flatter and smaller frontal area. The the pedal with the dimples is one. There are the dimples on the cleat two, which has a more aerodynamic shape. (The yellow bit in the picture) These cleats are sold separately and will fit the regular Speedplay Zero pedal. And, because they’re made of a grippy material make walking a lot easier and don’t do damage to your marble floor. They come with small caps that you twist in to prevent dirt coming into the clipping mechanism.

    And that is where the best part of the innovation lies. They are called the Walkable and are only marginally more expensive than the regular cleats.

    Of course there have been many real improvements over the years, but also an incredible amount of kidology.

    Didn’t seem to have much of an effect at the weekend.

    I’m not even saying the dimples won’t work. Maybe they do have some barely measurable effect. It’s the claim that dimples “create a smooth surface” that I find a bit silly.

    Also, I am happy to buy new stuff if it works better, looks better, is easier to maintain, or is more comfortable, more reliable or lighter. Being faster is a secondary consideration. “Faster” comes mainly from training and your position on the bike anyway.

    I love Speedplay pedals, but come on – dimpled pedals? This is marketing BS at it’s finest.

  • Juns

    I think it is only good for moving and spinning surfaces (golf ball spins, so does a rim ergo the Zipp dimples)

  • Derek Biggerstaff

    All that matters is that some people will be credulous enough to believe it. We’ll all keep using our old stuff if they don’t tell us the new stuff is faster.

    “The golf ball like pattern is designed to create a smooth surface for the wind that maximises aerodynamic efficiency.”

    Er, no. The dimples create a rough surface (obviously). The purpose, at least in the case of a golf ball, is to encourage a turbulent boundary layer to form, which reduces drag by causing the flow to separate from the ball further downstream than it would in the case of laminar flow. God knows whether that works for a pedal though.

    haha 😀

    I’m going to attach golf balls to my whole bike now!

    If golf ball surface is so great, why they dont use it for the entire bike surface?
