I've been rocking this set up on both my bikes for a while and it's awesome.
One has the same gearing as you, Jon, and the other I have a 30 t chain ring
and use the 45 for a bail out gear. A couple of things I noticed with the 45.
First, chain length on some bikes is exact. On the 275 Nomad, there was almost
no chain tension in the 11 t cog and the derailleur only has a bit of play
left in the 45 t cog with the suspension bottomed out. However, with a bike
with less chain growth (Knolly), the conversion was super simple and had some
room for error for the chain length. Shifting is also very slightly worse with
the OneUp. Most of the cassette is fine, so is the 45 t, but you'll notice the
difference going from the Shimano cogs to the 18 t OneUp cog. Having said all
that, I would buy it again in a heartbeat. I love the bail out gear on one
bike and I love that I have a little longer gear on the other. I bet OneUp
will sell a bucket of these when the new XT comes out.
