Conversion Kit Crank Set Chrome, Converts 1 Piece Crank to 3 Piece Crank, 128MM Axle

I was actually told this may not fit my three-piece Tourney Cranks from the 80s for my 1985 Haro master well I was actually surprised they fit and I actually did a good job. Well finish and quality may not be the best as a higher priced ones these actually get the job done to convert your three-piece cranks or put them on your bike and in all honesty they can’t be seen anyways behind the chain and the cranks. I wish they were sealed but since my bikes will never be in rain and mostly for indoor show I don’t really mind great value for the price

This can add some new life to an old bike that you might otherwise have to discard. I have used these more than once and like them.

👍

It isn't top of the line by any means, but it was perfect.I only give this 4 stars because it is cheap, but for the price... it is great.Parts are a little cheap, but not cheaply made. Just things like lower end ball bearings are low end products, smaller grove in the lock ring washer allowed it to slip. (had to just disassemble it and pop it off... no harm no foul.) I personally don't know, but I assume the reason the price of this product is so great is because of cost cuts like these. The fact that these are my big problems is great... I can replace all these things I am complaining about very easily, and very cost effectively if and when they do fail.I have a family of large people because we love to eat homemade food from scratch. In an effort to lose some weight, we bought tricycles for the family. Hills still killed us, so we got pedal assisted motors for the trikes. My fat ass folded a tricycle, I got a mountain tricycle with a higher weight limit, and needed to change the crank assembly so I could attach an electric pedal assist sensor. This one ended up being the one that looked like it would best fit my pedal assist sensor. I wanted the expensive one but needed this one. Took me about 2 mins to install. Including hammering in the cups. (used a rubber mallet, it worked perfectly) I installed it once and didn't like how tight I had made it. I had to fully disassemble it to pop off the lock washer (it twisted off the grove that held it in place.) Took me about another 2 mins to reassemble it, and it works fine. My crank arms from my other tricycle also fit on this product, so I didn't have to buy the rest of a 3 piece crank assembly. If this happens to be the one you need, it is worth every penny... and it cost almost pennies... it is great so far...

Easy to install, good quality, don't forget to grease the bearings before installing

That's working very good

It started shearing the threads on both sides the same day of the install. These are incredibly unsafe and cheap quality metal. I’ve never seen anything fail this quickly before just from a bike ride.

This is the item needed in a motor kit, the kt does not include this, you won't figure it out till you start putting it together , you also need a better rear sprocket the kits sprocket is a piece of junk
