    I have been eager to switch to Speedplay for quite a while and took the plunge today. Having picked up a pair of X2's at one store I then swung by another to purchase some new road shoes (the pair I have been using to date have been mountain shoes).

    I settled on Shimano SH-R151 road shoes. They felt comfortable and light and the bike store even took the time to fit the cleats for the X2s, which was nice.

    Anyway, I got home, installed the X2s and went for a few lengths of the road outside our house. Aside from the predicted feeling of "being on ice" (which doesn't really feel like a bad thing - just weird), I took to the combination pretty quickly. Dismounting the shoe is an interesting process and one that will take a while to perfect. However...

    On reading the Speedplay site tonight I am told that the X series pedals are NOT compatible with "carbon fiber" Shimano shoes because the base is too wide (the cleat seems to fit perfectly though).

    Am I missing something? The SH-R151 has a "carbon fiber composite" base. So, is this one of the incompatible shoes for the Speedplay X2s? Frankly, I am not sure what to expect in terms of being able to dismount the pedal from the shoe. It SEEMS OK but perhaps I am missing a better experience with a different shoe.

    Anyone used this combination?

    Thanks.

    One thing I forgot to add is that Speedplay have the following on their web page:

    "X Pedal-NOT COMPATIBLE. Although Standard Snap-Shim cleat will mount to the carbon sole, this shoe is too wide to clear crank arm, preventing safe release. Special longer spindles available from Speedplay must be used to ensure compatibility with carbon soled shoes. "

    Has anyone obtained these from Speedplay? I'm interested to know if this completely fixes the issue or it's a "kludge". I don't want to take any compromise with my pedal/shoe combination and I am still able to return the shoes (I want to keep the Speedplay X2s). However, if it's a simple fix that has no downside then I'll get hold of the longer spindles.

    Anyone have any experience with these?

    Thanks.
