Quick Release Pedals for Easy Tool-Free Pedal Change on Dual-Hole Cranks

Quick Release Pedals for Easy Tool-Free Pedal Change on Dual-Hole Cranks:
----------------

Project*:

MKS Ezy pedals are detachable and mount to the crank with a quick release coupler. They can be used to quickly change between pedal holes on dual hole cranks. MKS Ezy pedals come in a variety of types - platform and clipless. The MKS EZY Lambda / Grip King pedal is likely their best platform pedal for uni.

For this to work you will need 2 sets of the Ezy Pedal Adapters (QR pieces). You can either buy 2 sets of Ezy pedals, or 1 set and get a spare set of Ezy Pedal Adapters. Also - MKS makes many other non- QR pedals, but the axles on some are switchable with the Ezy axles (you have to take apart the pedals for this - I actually did this to make the Lambda Ezy pedals below).

*See the conclusion below - this setup has its downsides and areas for improvement

----------------

Equipment:

-MKS Ezy Pedals with 2 sets of QR adapters

-Pedal Wrench

- Dual hole Cranks with 23+mm of space between holes - KH 127/150, KH 137/165, Mad4One Triple hole (skipping middle hole). You would need to grind down the QR adapters a bit for narrower sets of dual holes.

----------------

Setup:

- Mount QR Adpaters
Mount the QR Adapters with a pedal wrench. Mounting can be a bit awkward - grease the threads and mount the adapter to the inside hole 1st.

- (Lambda / Grip King) Grind Inside Corner of Pedal
The Lambda / Grip King pedals have a wide platform that will touch the unused QR adapter in the other crank hole. Use a dremel or grinder to remove a few mm from the inside corners (see pic).


- (Lambda / Grip King) Add Pedal Spikes and Guides
For better grip, I would recommend adding pedal spikes into the holes on the platform. The unused QR adapter in the other crank hole protrudes enough to catch your shoe if your foot is not on the outside of the pedal. I recommend (but have yet to try) putting some kind of guide on the inside of the platform to force my foot to the outside.

- Insert Pedals
Insert the pedals into the QR adapter in either set of crank holes. the pedals have a yellow clip to prevent accidental separation of the pedal from the QR, but I never used these and had no trouble.


---------------


Conclusion:

After setting this up, and riding it for a week or so I found that changing the pedals was indeed a lot easier and interrupted the floe of my rides less. I live on the side of a valley, so a lot of my rides have long climbs and descents where switching the pedals to a longer crank hole for climbing, then switching to a shorter hole for the descent makes sense. I only rode this setup on roads and very easy trails.

I also found a few downsides to this setup. Foot placement on the platform pedals had to be on the outside of the pedal otherwise the QR adapter in the unused crank hole would push my foot off the pedal. This was very awkward at first - my foot would get lifted off the pedal slightly then (usually) slip back down on to it. After a a couple of days I got used to placing my foot on the outside of the pedal. I could not use the clipless pedals because my cycling shoes were to wide. I think these have good potential if using a narrow road racing shoe though - the clipless system holds your foot in place and prevents it form hitting the QR adapter.

-----------------------

Note:

This setup has been tried before in this thread:

http://www.unicyclist.com/forums/sho...=111424&page=2

but I thought a more detailed post on setup might be helpful here. The other thread has some good ideas about other MKS Ezy pedals mods and a wellgo QR pedal too.


----------------------

Disclaimer:

I am just sharing what I've tried and sort-of worked for me. I don't guarantee it will work for you - heck, I don't even guarantee you won't get horribly disfigured or emotionally scarred trying the setup described in this post. Use at your own risk!

The QR adaptors look very much like Nitto Kohki Hi Cupla air line fittings.

The adaptors seem to work more-or-less like an air line coupler. Pushing in on QR the fitting will force a couple of ball bearings out of the channel in the pedal axle - allowing it to uncouple fomr the adaptor. Twisting the fitting has no effect - there is no twist to lock setting on it.

Now that I'm guessing you have at least a few miles on them, how are they holding up?

They're holding up alright, but I just couldn't get used to the narrow profile of the Lambda pedals (even narrower when I had to move my foot a bit to the outside to avoid the QR adapter). My feet aren't that big either - size 9.

I ended up taking them off my uni for now. I may try to modify the platform to make it wider. Either that or the pedals will sit in my parts bin for a while.

I suppose if anyone is really curious about this setup, I'd be willing to pass these on.

I think the other QR system shown by Kris in the thread I linked above may have some good potential: better platform options with the Wellgo QRD pedals.

Just to clarify:

The lambda pedals made me waffle: akward at 1st - got used to narrowness enough to live with it - tried regular pedals again and narrow lambdas seemed akward once more.

The "clipless" pedals I haven't tried to ride yet: based on measurements I would need a really narrow road shoe (or trim the sole a lot on current shoe). Plus I need to practice mounting clipless on my 36er. I expect Ill try this setup as it is "a stone un-turned" - which tends to drive me crazy until I have to try it.
