Hey Spacey, are you putting these on your Greyborg? I just ordered a pair from Doc, and am thinking of epoxying them onto the sides of my dropouts on my Greyborg.

Hi Doc, one last question...

Go to the video you made at 7:00 minutes AND 7:45...

In these two examples of attaching your torque plates you cut the frame dropout away so each torque plate fit, instead, inside that cut-out space.

Since your torque arms are so thick (& strong) it does look like you had to do this, cut the dropout away, so you would have enough (width) space for the remaining threads on the axle to attach the nut & wheels.

Is this correct? :?: Thanks! :)

Some people may have to do the same dropout mod in order for the axle to have enough remaining threads to attach the axle nut & wheel. :idea:

usually that fit perfetc and you still have around 12mm of thread for the nut. the torque arm is 3/8 thick.. not too much...

But on one of my ebike, you can see one of my very first torque arm.. that was actually 1/2 thick... and yes.. i had to cut the frame.. that's way i adopted 3/8 thickness after that. and that's why i only sale the 3/8 thick. 1/2 is too overkill and too complicated to install.

If you have steel or chromoly frame, you can bend them and install the torque arm inside instead of outside... by that way the motor axel will touch the torque arm metal wich is harder than the rest and avoid the nut to loosen due to too soft bicycle metal frame...

NEW BATCH OF 40 sets arrived today!!

It have 0.30mm wider slit for the axel, avoiding the problem of too tight axel... but is still overkill about strengh :twisted:


( I received alot of email from people that was worried and explained that they dont want to rework their torque arm and also that have bigger axel than 10.0mm. Best solution was to make some that have wider slit and still overkill about how their strengh but have more accessible width for any axel.. and also reduce the complexity of a perfect aligment from both side torque arm.. in case wehere you dont aling perfectly teh paralelism of both slit...)


The LOG:

First gen of torque arm of this thread: normal desing with too thight for most of the axel.. around 9.80mm slit... MIGHT need to reworked with file dependig on your axel

Last gen ( the one arrived today): larger slit to 10.25 to 10.35mm to cover ALL existing hub motor axel.

I'll email all of you before shipping everything to ensure you preffer the first gen or this last gen.

That's ALOT OF WORK !!!.. more than i thought .. :lol:

On each set I have to:
-drill to enlarge the hole perfectly to prepare for the M10x1.0 to be threaded....
- make thread on all the right torque arm of each set by hand
- File the too cuting edge of each parts ( the laser cut is so cuting than the shipping envelope would not support it :lol:
-Clean and remove any cuting oil..

But i ensure all of you that everything will be shipped once i'll have finished all the sold set.

(around 35-40 set sold from now)

Hey Doc,

I've just installed the torque arms on my kmx this weekend and they are great!!

I sanded the steel torque arm & part of my kmx frame to install drop outs

i applied epoxy & then put motor in place on frame, added the nuts to secure the steels dropouts make good contact with frame,

I taped the motor axle with some masking tape to ensure motor axle and dropout don't glue together

word of caution, MAKE SURE YOU ARE CAREFULL NOT TO GET EPOXY ON MOTOR AXLE & BIKE FRAME OR DROPOUT OR IT WILL GLUE TOGETHER!!!

I had a touch of epoxy do this and it almost make my x5 and kmx one LOL...

be carefull

You're a good man Spacey for pasting up that link for UK members. Out of interest, I couldn't see DP420, I could see DP410 and DP460, what is the difference between those? Is the higher the number the higher the bond strength?

I have looked everywhere in Australia, and I can't find a seller, all the sites in the US won't post outside US, I presume that is because of the strength of the epoxy, in case it spills in transit?

I am thinking of calling 3M in Australia direct, but they will probably insist I buy 10 cases of the stuff.

For those readers with an Hx35 motor, the 1st gen plates fit perfectly over the axles. I haven't even had to file out the plates, they fit tight as a nun's nasty on my HS35 axle...

So have I but no luck anywhere... It has been the main thing stopping me from buying these. Let me know if you have any luck.
Cheers for the heads up on the hx series to. I was wondering how tight they would be. :-)
Think ill go ahead and order a set now. :D

The last two digit are the time they have for the worklife.. 420 = 20 minutes. after that yuo should not move the part but just leave them to cure fully.

Best to full cure is at higher temp like 100 celsius.. it take less than 30 mintes.. but that will require yu to put the parts in an oven... :? but lower temp just increase the curing time

Ambiant take 24-48 hour

DONT FOEGET"" EPOXY IS ONE OPTION... but you can use bolt to fix them if you have the room for... the metal of those torque arm and the surface i designed them is strong enough to allo holes on the T-A

2 or 3 per torque arm of these bolt (10-32 is best as well as M5 bolt too) will do the job

or many smaller will do the job

Just use a GOOD QUALITY DRILL BIT TO drill the hole in the T-A.. this metal is pretty hard :wink:

Yes they can be adpted the way you want.. but on this model of MTB you might need to cut a bit the horizontal part of the actual dropout above the axel... or just install the torque arm inside the frame and not outside.. but you might need to bend a bit the frame by 3/4" wider.
I'm still waiting for the 5 sets of torque arms, I hope they will arrive soon.
Everything is shipped.. you should receive them in couples of days... :wink:

For Aussies looking for the DP420 epoxy (I looked everywhere), IceKreme1002 kindly pointed me out ebay number 110732459169.

Although his listing doesn't say he posts to Australia, he does, he will post to Australia for $13.25, which will cover up to 4 tubes.

Does anyone know where I can buy the DP420 in Canada, or more specifically, Toronto, Ontario? The 3m website says that shipping is not available to my postal code for some reason. Otherwise I'll just use eBay but I'd prefer to buy it at a store. Thanks!

Ebay is your best bet. I looked online and see that it's a commercial product that isn't readily available via consumer outlets. If you can buy it online, they don't give a break for either volume or price.
