Also, die 525er sind die LX (manchmal auch mit DX bezeichnet). Kosten ca.
130,-DM, sind *leichter* (ca. 10-20g) als die 737er und sind auf *beiden*
Seiten mit Klickmechanismen versehen. Die 737er sind das XT Modell. Sie unter-
scheiden sich von den 5ern dadurch, dass sowohl der *vordere* als auch der
*hintere* Einstiegspunkt auf jeder Seite des Pedals beweglich sind. Die 5er
haben nur einen beweglichen und einen festen Punkt. Die 737er kosten ~200,-.

Subject: 737 vs. 535 SPD Pedals - Summary!!

Here's the Nets general wisdom on 737 vs. 535 clipless pedals:

1. 737's are easier to get into *initially* as you just have to stamp
   your foot down.  %35's have to be "toe-in" first.  This difference
   betwen the two diminishes with practice.  535 owners have no problems
   with entry.

2. Both are equal in exitability.

3. 737's are not worth the extra bucks.  Put your money into a better
   shoe.

4. Some felt having two release points on the 737's was an advantage -
   if one gets clogged the other can still move.  Others point out that e
   the 535's have fewer moving parts and therefore are less likely to fail.
   These points seemed to be speculation and were not substantiated by  o
   experience.  Again no complaints or failures voiced from owners of 
   either type.


Thanks to all that wrote.  Hope this helps others.

This may be an FAQ, but here goes...

>   What's the difference between Shimano's M525 and M737 SPD pedals?

The main difference (other than price) is that the 737s (generally known as  
XTs) have a catch front and rear, while the 525s (or DXs - yes I know that 
5-5 should mean LX, but everyone calls them DX except the saddest technoweenies
) only have a catch at the rear. In practice this means that the XTs are 
slightly easier to get into, as you just have to stand in roughly the right 
place. The double catch gives a greater margin of error. Mind you, some people
reckon the DXs are easier to get into. Hey ho. Other differences...the DXs are
a *tiny* bit lighter, and have fewer increments on the spring tension adjusters
They also look a bit more robust, having fewer cast alloy parts, but I have no
evidence to indicate that they are stronger.

>   Do they both have binders on both sides?

Yes. The only single-sided SPDs are the road bike versions.

>   Any recommendations for inexpensive shoes?

There's a *huge* number of SpuD shoes out now. Try the Shimano MO-50 (just
replaced by MO-51), or Caratti enduro (might not be available in the States)
Specialized have just come out with a couple of new Ground Controls that are
cheaper than the originals. You may have a problem finding shoes to fit if
you have very wide feet (like me). Try plenty of pairs.

When you start on SPDs, it is recommended that you use minimum spring tension, 
but when I did this, my feet just popped out all over the place. I started on 
one-third tension. In fact, I'm still using one-third tension, 'cos its muddy
outside and it makes it easier to enter/exit in a hurry :-).

Have fun, and ignore the laughter when you fall over...
