So, I got the wheels with the BT45 tires back on the bike. It's a
to do it with one person, but it can be done.
I've put in about 20-25 miles (I had to make a run to the office) and the thing that probably stands out the most with the BT45 compared to the IRC tires is that they drop into a turn quite a bit faster. I'll have to get used to that.
