Sorry, mounting spd cleats on Shimano carbon shoes?(6 posts)

Sorry, mounting spd cleats on Shimano carbon shoes?K-Man

Kind of a newby to road items so here is the stupid question of the day. I just bought a pair of Shimano MegaPavemantis Carbon Road Shoes and using Eggbeater pedals on my road bike. Can I mount the cleats (spd) right to the bottom of the shoe or are some plates/adapters required. The mounting slots on the bottom of the shoes do not look centered (side to side) as they are on MTB shoes. Also mounting the cleats will obviously do some damage to the carbon.

Thanks

I have the same shoes, and I use SPDs. Mounting the cleats directly to the bottom of the shoe is the only way they work for me. When I tried to use a plastic pontoon between the cleat and shoe there was too much cleat movement.

with no problem. The only "damage" is sort of a permanent indentation in the carbon where you cinch the cleat down, but no functional impairment is far as I can tell.
SPD might be ok, don't do time ATAC though!granda

That is why I am asking, the Egg Beater cleats are pretty much the same as ATACS....for that matter they are similiar to SPD other than the material brass/steel. Why would using SPD vs ATACS be any different?

Thanks....dont want to ruin my first set of road shoes.

Well, first of all, they weren't brand new cleats, but they weren't worn either. SPD seems to support more of the load on the cleat/pedal itself as opposed to the sole. When I put the ATAC cleats on my Shimano carbons the two metal support bars from the pedals started digging into the sole. There also seemed to be more float with the ATACs vs. SPD and this would cause a lot of friction. Eventually (3 weeks) edges where the cleats hung on to started to deteriorate and it was hard to keep them tight and level, until it ate away all of the carbon. Either way you go I think your carbon shoes will wear out VERY fast, the upside is that they are very very light and even more stiff. I really noticed the difference from nylon soles it is huge (like me I weigh +200). Just don't be surprized that you'll be buying new ones in 6 mos - 1 year at best, I guarantee it if you use them daily.
