Simon Brooke said:SPD-R and SPD-SL really have nothing to recommend them. They are simply
Shimano's attempt to produce a pedal which is a close as possible to a
Look pedal without actually infringing Look patents. The SPD-R, in
particular, uses a bolt pattern incompatible with anything else so you
either have to use Shimano shoes (which don't fit me) or use a heavy
adaptor plate, which is madness.
I second this, more or less.
When I first decided to go clipless, I went for SPD-R pedals,
perceiving them (from my limited perspective) to be a step up from SPD
and cheaper than SPD-SL. Had I done a bit more research, I might have
chosen differently.
The problem came when I decided I wanted to also fit clipless pedals on
the hybrid I was using for commuting at the time. I wanted dual-sided
pedals so that I didn't always have to wear cycling shoes, and I wanted
shoes that could be worn comfortably off the bike. Neither option is
available for SPD-R, so I had to switch over to SPD to get what I
wanted.
That said, in use, I prefer the SPD-R pedals because of the larger
platform and the float, so if I were only interested in road
racing/training type riding then there would be no problem with them.
Except perhaps the fact that they now seem to be obsolete and being
phased out in favour of SPD-SL.
Also, I haven't yet tried Look pedals, so I have no point of comparison
between them and SPD-SRs.
Quoted message said:In that case you probably do want the original SPD system, or one of its
low cost clones (e.g. Wellgo WPD982, Shimano M324).
Shimano M324 is what I fitted to the commuting bike and I think they're
great - and contrary to what others have said, I have never had a
problem yet with trying to find the right side of the pedal when I
needed to. YMMV.
