Fitting clipless shoe cleats accurately is vital for strong healthy pedalling. All of your power is transferred through your cycling shoes, and the cleats you fit to them and into the pedals. If the cleat position is even fractionally off it can cause a reduction in power but more importantly it can cause you pain and discomfort. If you leave cleats badly adjusted you could end up with a long term injury. So, avoid all that by following these simple steps to a well adjusted cleat.
Tools and materials
Setting up three-bolt cleats (Look, Shimano SPD-SL etc)
Shoe cleats wear out. Worn or damaged shoe cleats can be dangerous as they can be unpredictable in their release characteristics. The cleats pictured still have life left in them, but paying close attention and replacing in good time will keep you save and enjoying the ride.
Whether your shoes are receiving their first set of cleats, or you're replacing worn ones, when you've got the bare shoe midsole exposed, give it a proper clean and degrease. Inspect the midsole for damage and the captive threaded nuts for clean threads.
Grease the threads of the captive nuts. It's easy to rush the fitting and set them dry and forget about them. A small dab of grease helps the cleat bolts engage and really helps when it becomes time to remove the bolts when replacing the cleats in future. A needle nosed grease gun helps with accurate application of small amounts of grease.
Fit the cleat hardware. In the case of the Shimano SPD-SL cleat (in this picture) this means the three oblong slotted washers and the three domed head bolts. Do them up tight, but not screamingly so, you want them to be firm enough to engage and disengage carefully - without moving, but you're likely to need to make an adjustment or two before finding the 'sweet spot'.
As a basic rule of thumb, you're looking to position the shoe cleat so that it's centre point is just inboard of the ball of your big toe. Laterally, the front (tip) of the cleat should follow the line of your middle toe. These are good starting points for basic cleat positioning on a new shoe. Naturally if you're replacing cleats on shoes where you've already achieved good cleat position, use the marks they've left on the outsole as guides for the new cleat.
There's not substitute for riding to feel what changes need to be made to the cleat position to work effectively with your specific biomechanics. We use a turbo trainer for safe, repeatable pedalling when we set up shoe cleats. It allows us to pedal and keep looking at our feet and concentrating on feel without coming to harm from traffic we didn't see. If you don't have a turbo trainer, use a quiet piece of road that is free from traffic and pedestrians. You also might want to reduce the spring tension on the pedals to help make entry and release easier while your homing in on the perfect cleat position.
Unless you're very lucky, it's likely that you'll need to make a small positional adjustment or two. A millimetre here or there or half a degree of rotation can make all the difference to your pedalling action, comfort and power output, which is why we didn't do them up massively tight in the first place.
When you've tweaked and retested the new cleat position and are happy that it's perfect, give the cleat bolts a final tighten. Take care not to damage the bolt heads. Now you've got your cleat position dialled, take a permanent marker and draw around the cleat. This will mean future cleat swaps should take seconds and require no further positional work.
Setting up two-bolt cleats (Shimano SPD, Crank Bros etc)
Twin bolt recessed cleats have two pairs cleat bolt location options - fore and aft. Which you use will depend on your personal pedalling style and biomechanics, generally most riders we know use the rear ones to place the centre of the cleat just inboard of the ball of the big toe, as per the road cleat advice.
As with the three-bolt road pedals we've just looked at, grease the threads of the captive nuts. This will mean you're using less force to do them up. They'll do up tighter, but more importantly, especially if you end up riding cross, gravel or going mountain biking they'll undo when it's time for replacement. Even though they're steel and not plastic, they'll wear out eventually, creating a vague and inconsistent entry and exit, and a rattly and loose feeling in use.
Present the cleat to the outsole. Use your knowledge of how your foot prefers to sit on the pedal to make the basic positional adjustment.
Next to fit is the bolt retaining plate. This has countersunk fittings to allow the Y shaped bolt heads to fit flush into the cleat body. Make sure you get it the right way up.
Fit the two cleat bolts. Use a 4mm Allen key - with a good fit to the bolt head - and note that you'll have to slightly counter tighten the twin bolts to achieve an even torque to each bolt. Take extra care if setting up Crankbrothers cleats, as in our experience the bolts heads are softer than Shimano's and therefore easier to knacker with worn 4mm Allen keys.
The two-bolt cleat has a range of lateral positional adjustment. As you go through the same adjust - test ride - adjust process as the three-bolt cleats you can also adjust the shoes proximity to the crank arm.
The rest of the fitting, adjust, ride, readjust and final lock down procedure for the twin bolt style of cleat is as described for the three-bolt cleats.
I suppose this would also improve one's pedaling style as well, even when riding a non-fixie. Hence why so many road pros start out track riding....
