As the instructions in the box say, it's not intuitive but once you learn how to use the chainlift it is really easy. I have a direct mount derailleur so it didn't fit my bike out of the box. However I wrote in and they set me up with the adapter and now it works great and I would definitely recommend them. If you have any issues definitely reach out before getting frustrated.

I purchased two new bikes, one for me and one for my wife. As new models, the derailleur hangers were slightly different from my older bikes. I contacted Fernando for help with the Chainlift tool I purchased last year. He recomended two new pins he had created for these new hangers, sent them to me and both worked perfectly! I'm a big fan of Fernando and the product.

Perfect

Purchased this product and had difficulty getting it to work so emailed Fernando.
A swift reply and photos sent a special pin was sent as my rear mech was a direct mount.
I now have 2 Chainlift’s and honestly cannot fault the product and customer service.
I have changed wheels both with and without a work stand and found it so simple.
