Good Quality
I bought these as an aid to my partner's cycling as her arthritis means that getting the pedal action correct would help with her hip pain. I was sceptical whether a 10mm adjustment to her old cranks would really make much difference but I was amazed to find that it actually did and her cycling comfort improved 200% immediately. These cranks are easy to install if you have the right tools (although getting the old cranks off was the more challenging problem). Very good product as far as I can tell

Extra short kid sized crank arms 89mm
Great extra short “kids crank arms”. These were used to modify a bike. A great quality crank arm at a size which is hard to find. The bike fitter was amazed.

No fuss no drama
Not a lot you can say about a set of cranks, but it is worth pointing out that both the left and right are cranked, this makes them perfect if your doing a Bafang mid drive conversion, as I was. Solid 5 out of 5 for doing what they should and a lot cheaper than a set of buzzbars too.

get on your bike again with new cranks
I've had surgery on both legs leaving my legs much shorter and unable to ride my bike so I bought 2 crankshafts shorter which now allows my legs to reach the pedals and ride my bike and at a very cheap price., so I'm very pleased 😄

Sehr gut Qualität!
Mega stabil und wie beschrieben. Konnte damit mein Fat-Bike sehr gut reparieren. Ein externes Werkzeug zum Abziehen der Kurbel ist trotzdem nötig.
