I have this 3T cassette on my titanium Birdy mounted on a Hope XDR road hub. But the XDR hub isn't necessary, this cassette fits on a XD hub too.

From factory, my Birdy had a 52-36 front and 11-28 rear. 52-11 is too short for a ETRTO 355 wheels bike.

I had to build a new wheel because the original hub cannot support XD or XDR (its freewheel body isn't exchangeable).

The 3T cassette works perfectly with the original 11s Shimano 105 derailleur and now also with an Ultegra 11s derailleur (both with long cage).

When I swapped the original wheel with the Shimano 11-28 cassette for the new one with the 3T cassette, I had almost no derailleur adjustment to do. I had only to increase the length of the chain to accommodate the bigger 32t sprocket.

With this cassette on a small wheel folder, the range of the cassette is almost big enough and I only seldom use the front 36t small chainring.

This kind of cassette is ideal for a fast small wheel folder, it avoids the big 60t front chainrings.
