Pls Help. Pedals to Cranks Compatibility

[Rufus Chh]

Hi guys
I have the Shimano Ultegra R8100 crankset. I am not sure if the Shimano Ultegra PD-R8000 pedals I intend to buy fit the cranks. Please help.
Thanks.

They’ll fit

pedals tend to be compatible with any crank unless you have an odd crankset like a childs one .

There are 2 sizes of pedal thread, 9/16ths and 1/2 inch (apart from weird French stuff in the 40-50's) 1/2 inch is generally BMX while everthing else is 9/16th

Just make sure you pay attention to the R and L pedals and fit them on the correct crank arms. The Left pedal screws in anticlockwise.

Easy way of remembering is that both sides screw in towards the front wheel and unscrew towards the rear wheel. Put some grease or copper slip on the threads and don't overtighten.

Plus fit and tighten gently with fingers only, to initially engage the threads.

Is this the first time going clipless?

Shimano pedals seem a bit pricey, worth considering other shimano compatible pedals or even looking (unintentional pun) at Keo pedals.
You can get reasonable pedal+cleat sets from £40 upwards.

I just remember that the right one is right and the left one isn't right. (Makes sense to me)

As an aside: 1/2” pedal thread size is for 1-piece cranks (As far as BMX go’s). So generally 80’s stuff. Or cheap ‘Catalogue / Department Store bikes…..

Anything remotely modern; with a 3-piece crank takes 9/16th thread 👍

I’ve used Look Keo for years
