Hi
I mentioned “cheaper” relative to the M-Force 8 that some had used, which is a Titanium rather than Aluminium body.
The ones I actually bought were from Amazon UK: https://www.amazon.co.uk/gp/product/B001E0PZLO/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1
However it looks like they no longer have stock.
I think the online shops are using an old photo which is what is confusing you.
This is how they look in the box (tapered axle), different to the Amazon photo.
Bike 24 in Germany have one pair: https://www.bike24.com/p292993.html
However Xpedo are no longer listing the M-Force 4 on their website, so it may be discontinued: M-Force 8 and CXR are still there.I would add a photo of the axle if I could figure out how!
Just found this thread, nice solution getting an power meter pedal for cx/gravel, instead of waiting until SRM get itˋs X-Power to the market.
My only concern will be the clearance of the shoes (S-Works Recon) to the pod. Does anyone use the S-Works Recon or may provide measurements concerning the distance from the pedal center and the height to the pod? I do not want to cut something out of my shoes to get the right fit.
I mounted my Duo’s to some CXR’s but was unable to get the washer off the CXR spindle. I was able to get the o-ring off but not the washer itself. I ended up putting just using the o-ring (no washer) because I was impatient. I may try again to get the CXR washer off but so far everything seems to be working well. I just needed to trim a small amount off my shoes.
Tried this with a pair of CXR’s had the issue where the pedal will not spin if the end bolt is full tightened. Tried all both combinations of washers (the pressed on CXR with and without o-ring and the Assioma one).
Can someone ( martyhenderson or other) confirm that M-force 8 work properly i.e. with the washers included and the end bolt torqued to 9Nm?
To be verified properly later… but for my set of CXR’s it doesn’t look like the pedal body is interfering with the pod, more that when fully tightened the bearings are pressing on the internal faces of the pedal body and binding, whereas the bearings should be pressed against the raised points on the pedal axle.
Tried the conversion using the mforce-4b and found that the end cap of the assioma won’t fit on the xpedo pedal end, if I tighten the bolt the end cap starts pressing against the power meter sensor and won’t rotate. Anybody had to trim the end cap so it could fit the xpedo pedal? I tried without the end cap but then there is a little play. Any suggestions?
It’s a shame that the Xpedo flat / SPD pedals have a slightly wider Q factor (I assume this means a different length spindle). I’ve love to have made a ghetto flat pedal setup.
I actually do the CXR pedal bodies in my video but I removed the washer. With the washer, there is too much tension on the bearings. One pedal I did not remove the washer and it was too tight, so remove the washer and the spacing is perfect.
I used the CXR pedals, I also cheated and ended up using threadlocker (the blue one so i could remove the bolt later), tightening the bolt down to where the pedal spun freely with 0 lateral play. Let the threadlock cure for 24 hours and haven’t had a problem since September.
I did the conversion with a set of CXR’s and had to issues with the pedal spinning. From inside to out here’s the way it worked for me:
Assioma spindle → CXR o-ring → CXR pedal body → Assioma end nut → CXR dust cap.
Everything is tightened to 9Nm and spins freely. I initially tried using the Assioma inside washer (too tight) as well as the Assioma dust cap (too tight).
Thanks for the info.
So in summary the CXR “works” but isn’t fully compatible as the bearings on the crank side of the pedal loose the protection from the elements that the washer and o-ring combined provide. The bearings might fail sooner but at $25 a set it’ll take years before this approach will cost as much as SRM X-Power…
Also - the price difference between the CXR vs the M-Force 8 is almost £100 for me in the UK. I couldn’t justify the expenditure on a pair of pedals, sure they’re a lovely bit of kit in titanium but not for a fat lad like me… Leave that for the front of pack weight weenies!
I was curious about this as well. I emailed ISSI and this was their response:
“Thanks for reaching out. While our spindles are very similar to those used by Xpedo, I can’t say 100% that they’ll work with what you’re trying to do. Consequently, I can’t really recommend using them for the swap.”
Not sure if they are just covering themselves or what, we’ll have to wait and see if someone on here has them and can confirm.
Good of them to reply. Probably covering us (Assioma owners) more than themselves as ISSI wouldn’t have liability for a modification like this, but it would invalidate the Assioma warranty. My pedals are now out of warranty so have Xpedo CXR on the way to test out how it works for the new Orbea Terra en-route to me now.
