Review: bingo - just the ticket.
Review: Great GT2 pulleys for DIY projects - I recently bought these GT2 20-tooth aluminium pulleys to use in a small DIY project, and it has been a mixed bag. The machined aluminium feels solid yet lightweight, and the precision of the teeth makes belt tracking much smoother. Installing it was straightforward and I found all the measurements to be accurately described. Unfortunately, for my order at least, I received 2 less pulleys than stated in the item listing. This might just be a one off so I've only docked one star.
