Had one not work and thought I’d give it another shot. The thread is soft and bad quality. Had both an origin 8 and shimano bottom bracket tear the thread apart. Made sure I was screwing in correctly (counter on drive side etc.) and it still ripped it apart. I’d definitely go with a notch higher in quality.

5.0 out of 5 stars Converted my trike to using 3-piece
Reviewed in the United States on July 1, 2020
Verified Purchase
This was used when I realized that....I didn't know that much about bikes anymore and had purchased the wrong 3-piece crank set. Well the crank set was for a mountain bike and I have a street trike with a standard bottom bracket set. After messing around with a bunch of different cup sets and bearings I found this converter and 15 minutes after taking it out of the box I was riding down the street loving my smooth turning 3-piece sealed-bearing crank set. For my application the bolts were the correct size and there were no issues with installation or pressing them in. I used a wood block and dead-blow hammer to tap them into place then cranked the bolts 1 turn at a time until it was set evenly in the bracket. If this thing catastrophically dismantles itself during use I will updated but it is really just a solid bushing/reducer so I don't expect any failures.

5.0 out of 5 stars Not for the inexperienced
Reviewed in the United States on March 1, 2020
Verified Purchase
First off, I build electric bikes for a living, so when I get an interesting old frame, I want to work with it. I had been doing bottom bracket conversions in the old style IE: cups, bearings and short crank kit. When I looked at this product, I thought "Yeah!" But that was not the case. The inserts are deep, so if the crank stays, seat post or forward frame sticks into the bracket housing after welding, you have to re-shape the new converter. No biggie with a cut-off wheel on your grinder, but don't breath the aluminum dust. The three bolts did not exactly clear all the stuff poking through the inside of the bracket, so a little Dremel work to remove a little steel pipe in the way.
As far as the threading of the conversion, it is made for a sealed bearing set witch only depends on one side for support. No problem, just find out which side the new bearing threads into and that becomes the gear side. Using it with old three piece sets I have no idea how the threading would work, but from other reviews, I see that is an issue.
Finally, I would, and will buy this conversion for future projects as I now know what it's limitations and installation quirks are. Hope this helps.

I'm sure ots not a common problem, but the unit I received wasn't machined correctly on one side causing the barring cap to not fit properly. Other than that it seemed well made Whenever I have time to finish the bike I will be back for another.

If you have never installed this, there are tons of DIY videos on YouTube that are really helpful.

I'm switching to a 1 piece crankset to a 3 pieces crankset.
