Wellgo QRD quick-release pedal system

[D.M. Procida]

I've just discovered this:

<http://www.clasohlson.com/uk/Wellgo-QRD-Pedal-Attachments/Pr315113000>

a system of quick release bicycle pedals, so you can swap your SPD-style
pedals for a flat one very easily.

Is anyone familiar with this?

Neat idea, but I find that it's not spanner-wielding that takes the time
when swapping pedals. It's actually finding the others...

Not really sure what the point is, TBH, as it only takes about teo
minutes to swap pedals over anyway. So unless you want to change while
you're actually out on a ride...

Plus they seem to extend the effective pedal length, which I wouldn't
have thought would always be a good thing.

On a folding bike, taking off detachable pedals is neater than folding
pedals, but you then need to find somewhere separate to put the pedals.
And as a bonus you can change pedal type easily.

I've never been tempted myself though. (I hadn't seen that particular
design myself, but the MKS EZY range is similar:

I imagine that for a few people, being able to take pedals off without
a decent spanner at an airport when packing the bike for travel is useful.
Something of a niche market though.

There's another use for them I have realised. If I wanted to change
system from current SPD to, say, Bebops for use on several bikes. One
pair of Bebop pedals plus a pair of these adapters for each bike would
be a /lot/ cheaper than Bebops for all. Or even allow a much fancier
quality Bebop and still have change left over.

It's new to me. My first thought is that I wouldn't want the increase
in Q-factor. My second is, as others have pointed out, that it really
doesn't take long to swap pedals with a pedal spanner.

Except that the quick release fittings only accept pedals designed
specifically for them. Wellgo do appear to do a Look compatible road
pedal as well as SPD and platform, but for Bebops I suspect you are out
of luck.
(I suspect you personally could design and make or have made replacement
Bebop axles which would work with the adaptors, but that's not an ideal
general solution.)

A quick release adaptor which accepted standard pedal threads and screwed
into standard cranks and didn't move the pedals too far out would be
challenging at best, impossible at worst, depending how far out is "too far".

I rather like my M324's on the road bike (flippable, with SPD and
flat). The MTBs have M540's (nowt but SPD). Suits my uses.

I'm not sure quick release is a brilliant plan on an axle that's
continuously under stress and pretty close to any objects in the road,
to be honest.

Think of the anti-theft benefit. If there's no pedals, the thieves
can't pedal away. I prefer it when they remain "just lookin'".
Easier than carrying a wheel around town.

I used to have some ALDI-brand pedals of that type, but more than once I
hit the road with them when cornering.

How do you know it does that?

Sure, but I can imagine happily taking 30 seconds to swap a pair of
quick-release pedals when I wouldn't spend three minutes doing it with a
pedal spanner.

[Jaimie Vandenbergh]

These haven't tripped me up (yet!) - possibly because I only went
cleated when I started offroading about five years ago, and still have
keep-the-normal-pedal-off-the-ground reflexes on the road bike.

They are pretty narrow though, at least compared to my elephantine
feet.

Normally the inside of your foot only needs to clear the crank, with
these it needs to clear the latch too.

Have you tried them?

I looked at the pictures. How could it not?

Maybe it does. I don't see how it's obvious just by looking.

Rob points out that the latch means that additional clearance is
required, which is probably right.

However the red latch in the pictures can apparently be rotated into
different positions around the spindle, at 90-degree intervals, so it
doesn't have to be on top.

According to a discussion elsewhere, these pedals are about 62mm from
the centre of the cleat to the crank, compared with about 55mm for
Shimano pedals. I don't know whether that's a great amount.

If these things only work with pedals designed to fit them, it would
make sense to build the pedal such that the spindle is that much shorter
and the Q-factor isn't increased. If they worked with any normal 9/16"
pedal thread then the Q would be increased of course.

There's a good illustration of the spindle here:
http://www.aliexpress.com/item/Road-Bicycle-Pedals-Wellgo-QRD-W01-Professional-Bike-Accessories-bicycle-parts-MTB-Pedals-Cycling-pedals/369975394.html

It looks pretty secure to me. Nice piece of work.

[Rob Morley]

It has to be said that, contrary to popular belief, minimising the Q
factor isn't always a good thing - although it slightly improves
aerodynamics (and ground clearance when leaning) it's pointless for
people whose ergonomics require more widely spaced pedals, as it can
place stress on their joints and reduce their efficiency. That's why
these days you can buy spacers to increase the Q factor:

For avoiding potholes or negotiating rocks a wider tread path is
easier. The narrow tread path is most appropriate for economy of
motion when walking or easy running and transfers on to the bicycle
quite well for me. A wider tread may be more appropriate for
sprinting or climbing, so replicating the action of a man without a
bicycle when there are high power demands. For me that would be 180mm
between my ankle bones and 220mm between big toe joints with knees
bent. I don't ride like this on any bike so can't tell if the theory
matches practise. I suspect that it might well do and that for hill-
climb competitions or track sprinting (without steep banking) it may
show significant advantage. I feel it has a greater significance than
attempting to (erroneously) maximise crank length.

I'd rather look for splayed cranks as it is only under high power
conditions I feel it really matters and economy soft alloy cranks may
fail due to the extra leverage when combined with a slightly
enthusiastic rider. There wont be many fitting Q extenders to Dura-
ace or the like.

For example, see
http://www.thorusa.com/images/dahon/accessories/lambdasup.jpg

The innermost part of the pedal could easily be made closer to the crank
by flaring it as much as the outer.

However, you might have to put up with a thicker pedal to do that without
your sole interfering with the quick release, especially on the Wellgo
system - the MKS version looks neater (but may have other disadvantages).

I use MKS EZY pedals on our Airnimals. It makes packing them for
transport very quick and easy and it also allows me to swap pedal
styles for different types of ride.
