Should there be a washer between the pedal and crank arm? I have a washer in this position on my mtn bike (from factory that way) but not on my road bike.

The reason I ask is I installed a new crankset on my road bike. Old FSA crank did not have washers. New crank is Shimano. Pedals are Shimano.

What is the consensus on a washer between the pedal and the crankarm?

Thanks,

G.

Nah, especially if the pedal has a flange that acts like a washer.

I have one crank with pedal washers. Its carbon though, and I cant really tell you why there are washers there.

My Force (carbon) cranks came with washers, so I use them.

Now oddly enough, my mtb cranks (Al) from RaceFace came with them too.

Some pedals come with clear instructions that washers shall never be used since the threaded part of the axle already is as short as safely possible.

The washers are for pedals that don't have a flange. Non-flanged pedals tend to act like dull milling machines - they can tear the crap out of crank arms. The washers protect the crank arms; that's their only function.
