I'm going to give clipless pedals a try, with proper shoes. Can anyone
please make any recommendations?
Several people mentioned 'Look/SPD' in my other thread, but I'm not
quite sure what they are.
SPD is Shimano's name for several different and mutually incompatible
systems. However the original SPD is usually known as just 'SPD' and the
other systems are given a suffix - 'SPD-R', 'SPD-SL' and so on. The
original SPD was the first widely available mountain bike cleat system.
The original SPD system was at one time avialable for road-oriented
pedals as well (I have a pair) but these weren't very successful because
the pedal is small and concentrates the weight on a small area of the
sole of the foot. Vis a vis more widely used road systems it has the
advantage that the cleat is recessed into the sole of the shoe making it
comfortable and safe to walk on. However, like all ground-breaking
systems it has been rapidly surpassed off-road by other systems - Time
ATAC (my own preference for mountain bike pedals), Crank Bros Egg
Beater, Speedplay Frog, and others. The disadvantages of the original
SPD are
* Poor mud clearance - only matters off-road
* Relatively poor float
* Relatively poor engagement/disengagement
The remaining advantages of the original SPD is relative ubiquity and
cheapness of clone pedals, but frankly ATACs or Egg Beaters are better.
Note that none of these systems are compatible with any other, although
generally all mountain bike cleats fit the same shoes, with two bolts
side by side under the ball of the foot.
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.
Look Deltas are the most common road racing pedal system. The cleat is
very large, and attaches to the shoe using a triangle of three bolts.
Because the cleat is large and is proud of the sole of the shoe, walking
with these things on is less than wonderful. Look Deltas are widely
badge engineered (even Shimano used to buy Look pedals and rebadge them
- I've got a pair of those too). They are comfortable and reliable in
use but the pedals are quite heavy. Look have recently introduced a new
pedal system, Keo, which is slightly smaller and with much lighter
pedals. This is now my favourite road pedal system.
Other road pedal systems - Campagnolo Pro-fit, Time RXS, etc are each
incompatible with the Look Delta system but most use the same three bolt
pattern so work with the same shoes.
Quoted message said:Also, it would be helpful if I could get the pedals which have a clip
on one side but can be used with ordinary shoes on the other, as I
have only one bike and will continue to use it at weekends with
trainers and maybe sandals.
In that case you probably do want the original SPD system, or one of its
low cost clones (e.g. Wellgo WPD982, Shimano M324).
