Using former touring bike for indoor trainer. Have triple on it, so outside chainring sticks out a little more laterally than a double. LBS pointed out to me that was pedaling w/ toes pointed down through whole pedal stroke. So have been focusing on ankling (lowering ankle through bottom of pedal stroke). This is when started noticing the rub. Ankling fine for my other road bikes, but this one w/ the triple, my inner right foot now rubs the crank. Started to get tingling/burning pain on that side of ankle while riding (likely from hitting nerve there). Rode this bike for many years with no rubbing. Now that pedal stroke more efficient, don't want to return to old bad habits.

Have
-10 yr old Shimano 105 7 speed on this. Stem shifters.
-Old Time Equipe pedals/shoes that work fine for indoor

Would prefer not to have to replace cranks. If did, would imagine would have to reequip other parts of groupo.

OTOH, would prefer double to triple on this indoor bike.

Any suggestions?

Would not need to replace other components on bike if crank replaced.

Ankling not more efficient.

Sentences hard to read without subjects. Sound like Neanderthal.

"Would not need to replace other components on bike if crank replaced"-->maybe will simply replace crankset

"Ankling not more efficient" --> Perhaps I was using term "ankling" incorrectly. I am simply lowering ankle to nearly horizontal position, whereas previously toes were majorly pointing downward even at bottom of stroke.

Yeah, I gathered that's what you were talking about. Here are two short articles that I think you should read on the subject:

Bottom line: Do what comes naturally to you, but do it well. Steve Hogg is your daddy, BTW.

I had the same issue on my old tourer now mounted on the trainer. I have large and wide feet.

I solved the problem by moving my cleats over slightly.

There are also washer/spacers that can be fit on the pedal spindle to move the pedal out slightly.

Are these special washer/spacers?

If I were to get new crankset (see below), what else would I need? eg BB, FD/RD/Cassette etc
Currently have 7 speed Shimano 105 setup.

A new crank will most likely not help. Follow Az B's advise and look at pedal washers and moving the cleat just a little more to the inside of the shoe. You should be able to get pedal washers at any well stocked LBS.

Thanks everybody. Great ideas. I'll talk to LBS w/ your thoughts in mind.

Agree its foot position, cleat adjustment is the first step.

As far as pedalling goes, there are basically 2 styles, the pointed toe and the flat foot. In general, those who spin use the flat footed style, those who crunch use the pointed style. Which is better? Who knows. Some world champs use one style, some use the other.

The pain you are experiencing is probably from the change in style. If you are going to continue with the flat foot style, take a look at your seat height, your legs may be too straight at the bottom of your stroke.

Cleat cannot be moved side to side (only forward/backward) as is fixed in this plane.

Why will shifting to a double from Triple not help? A triple sticks out more distance laterally from the center of the bike (than a double). This is the side on which the rubbing is occurring.

Great idea. Had already looked at seat height which seems optimized. Will keep in mind.
