Clipless Pedal question

I don't know if they still make that size thread or not.  But you would need up date your cranks.

As far as shoes go....pick your pedals first then your LBS can point you to the shoes that are compatible with the pedals.  Most road shoes will work with most pedals.

I have a pair if Sidi that are ultra comfortable.  They are spendy but worth every penny in my mind.

Good Luck....

Thanks Casey and John.  Looks like my list of things to replace on my bike just got longer.  I was planning to change out the cassette, rear derauiller and chain and can now add the crank set and front derailler to the list with the pedals and shoes.  Any other parts that I should replace at the same time?  What about the gear shifters themselves?

Any advice or suggestions on what to look for, good website to educate myself with the options?  This bike parts stuff is all new to me.

Seriously correct, Leah.  I had posted that before I priced out new stuff.  I have a crazy case of sticker shock.  Right now I definitely cannot replace the bike since this bike is new to me and while it did not cost me very much, I have invested some money into it to get it ready for my first triathlon that I just completed and need to plan to use it for the next year or so.  I will be holding off changing the cranks, etc and will hopefully be able to get by with just changing the rear cassette and chain with components that will be better than what I have (slightly worn and rusted) and get me by for a while until I can afford to buy a better new or used road bike and even have a better idea of what I really want to have.

Just an update:  Thanks for all the info.  I found a single piece crank from Harris Cyclery online that has holes to fit the 9/16" pedal.  It cost me $20 to order and $25 for the LBS to install.  Now to learn how to use the clipless pedals without hurting myself too much.  This was definitely an inexpensive option to tide me over and allow me to save some money towards a new bike.
