Onza pedal conversion?

[Gtaddict]

Apologies if this has been asked on here before, but is there a way to convert Onza clip on pedals to work with the standard spd clips that come on a majority of clip on retro mtb bike shoes?
If anyone has any pics or a how to guide that would be fantastic.

Many thanks

Any good?

Sorry for being slow here - I re read your question a few times what aspect are you trying to convert ?

As I devout Luddite I don’t do modern and failing to understand the question
But I do ride 100% Onza

No, you can't convert OnZa HO pedals to work with shimano cleats. The cleat shape is intrinsic to the release and engagement. You need the OnZa cleats, which are a direct fit to your shoe.

SPD cleats aren't some sort of standard, there are currently 3 main brands, Time, Shimano and Crank Bros and cleats come with the pedals, not the shoes. Those three brands currently cover probably 99% of the market. There used to be more cleat types (OnZa for one!) but they've died out, but still use the same bolt spacing for compatibility. (Time experimented with a wider bolt spacing about 20 years ago, it only lasted for a couple of years.)

So that bolt spacing is the only real standard here....

I did read a thread on here a long time ago which detailed modifying standard spd cleats to fit onza pedals. I've no experience of doing it, just recall reading it. Search and ye shall find. Hope it has useful info in.

Hi Mattr

I think we are both mis understanding each others point here, I only use Onza and have done so from about 96 onwards due to their extra float and appreciate the differences in cleats and some peddles BITD came with the cavate that their cleats only had "emergency compatibility" with Shimano SPD ... or other marketing speak like that

but what exactly are you after ... do new shoes have wider spacing for cleat bolts ?

Wants to modify the pedal to take "standard" shimano cleats that's going to require new pedal parts, and (essentially) reengineering the pedal mechanism (such as it is)

Modifying cleats, that can probably be done with a dremel and care! But then they aren't standard.

No misunderstanding from my side at all.
The only "emergency compatibility" between OnZa and Shimano that i can remember was either not being able to engage at all. Or being locked in until someone prised the cleat out of the pedal. I stopped using them when i realised i could get all the functionality from many other pedals that didn't rely on elastomers for release tension!

And if you read my post, i said that time experimented with a different bolt spacing 20 odd years ago, they did it very briefly (only featured on their shoes and maybe carnac?), then went back to the standard spacing we have today.

Just checked, the wider cleat spacing was more like 25 years ago now. Shit i'm getting old

Okay I’m jogging on here, only dibbed in to see if I could help as I have 25yrs worth of spares hoarding but you obviously know what you want to achieve

It was wellgo or VP101 that I think offered up emergency compatibility never Onza, and referencing one of my earlier posts having exclusively used Onza I’m well aware of how they work and what happens when a friend offers you a go on their bike and you ultimately fall off due to your shoes (like you point out) being stuck in the pedal firmer than an Alabama Tick.
