Hello,

i'm wondering about the foot-to-axle distance with various set-ups.

say, i've look-drilled shoes. now, what would the distance be for

Look Pedals,
Speedplays (with their look adaptor)
Time (with the look adaptor)
Ultegra/DA SPD (with the corresponding adaptor)
DuraAce Look style
Keywin (heard about that one much lately)
Others?..

thanks much. -max

Hello Max
KEYWIN pedals give you the shortest distance ( at least of the ones that I
have measured ) from the top of the cleat or bottom of shoe to axle center
line is 17mm.
You can check them out at my site

Keywin did quite well at the Commonwealth Games. Sarah Ulmer is a Keywin
rider and she got Gold in the 3000 pursuit and silver in the points
race. Glen Thompson got a Gold in the points race and Greg Henderson got
the Bronze. Both Keywin men. Tim Carswell got bronze in the Scratch race
- again Keywin. The team pursuit got bronze with three of the four
riding Keywin.

The lowest foot-spindle distance you can get is with Speedplay pedals
and Sidi Shoes (with Genius soles). I don't recall the exact
measurement, but I believe it's on the Speedplay web site.

I guess you haven't measured too many pedals. For example, when the
Speedplay X-series cleats mounted to a shoe with a Look 3-bolt pattern
it is only 13mm; Bebop cleats are a similar distance; and even the Time
system's 8mm thick Look adapter plate only raises the entire shoe sole
to pedal spindle distance to only 16.5mm. When used with shoes these
pedals were optimized for (see note below), the Speedplay and Time
pedals and cleats are only 8.5mm from shoe sole to pedal spindle. I
haven'te measured them, but I'm sure that Shimano SPD pedals also
position the shoe closer than 17mm from the pedal spindle.

By the way, if you're going to be plugging your own products, you should
state your association to them.

(Note: The Time pedals are designed to be used with Time's shoes,
obviously. The Speedplay Slimline cleat is designed to fit partially
within the sole of Sidi shoes, reducing the shoe to spindle distance;
the pedal body effectively is in direct contact with the shoe sole.)

Well Mark
Obviously if I include my web site address in a reply then I am associated
with the product.
Furthermore I just measured a pair a Speedplay pedals and I admit that they
are lower to the axle centerline than KEYWINS > I don't see how you figure
8.5 mm or is this some speedplay company measurement?? Are you adding all
the plates??
In fact it measures at 13 or 14 mm when you count ALL of the plate thickness
VS 17mm of Keywin
Thanks for your concern
I notice that you have a .com.... isn't that for a business?
Do you ride or race?
Kind Regards

The measurement is very easy to derive. The pedal is dual-sided and
symmetrical top and bottom. The pedal is a total of 17mm thick, so from
center of the spindle to the top is 8.5mm. There are three plates total
in the cleat, one aluminum and two plastic. The two lower plates (the
alum. one and one plastic one) fit complete around the pedal, flush with
the top of the pedal, so they add nothing to the height. The last
remaining plate is slightly more than 3mm thick. But I must correct
myself, the total shoe sole to spindle distance with the Speedplay
system is actually 12mm (8.5mm + 3.5mm), not the 13mm I reported.

The 12mm distance holds only for mounting to a Look type sole. For
shoes with a Time 4-bolt pattern, the lower two plates mount directly to
the shoe without the 3rd top plate, so the cleat adds nothing to
pedalheight, and the shoe sole to spindle distance is only 8.5mm. For
Sidi shoes, the upper plate of the Speedplay Slimline cleat fits
entirely within the sole, adding no thickness to the shoe sole, so for
Sidi shoes, the shoe sole to spindle distance with Speedplay pedals is
also 8.5mm.

Yes, that is to indicate that my internet service provide (NETCOM) is a
commercial business, as are most ISPs. I have a personal account with
them for internet access for my own personal use, as do many others with
ISPs like AOL or Prodigy or Erols, for example. But I don't see what
that has anything to do with.

> Do you ride or race?

Yes, and yes.

Before this thread is completely dead...
I recently aquired a set of Time pedals for the low stack height and float
features.
But I find it extremely difficult to engage the cleats with the pedals.
Is it inherently difficult to snap into these pedals? Are my cleats too
worn, or out
of the (non-adjustable) correct position?
I have never had this problem with the Look design. What gives?

I've ridden everything (well, Look, Time and SPD) and the Times are just
tricky. They get better with practice, but I've never found them as
intuitive as anyone else's brand.

Stack height of major pedal brands can be found on the Speedplay website
