Unfortunately, a 14T with chain leaves uncomfortably low clearance on the bike if also running with a case saver like the one I made.
Here are pics of a new Dirt Tricks 14T compared to a worn 13T. I'll be sticking with 13T and have opted for a 45T sprocket on the wheel to test with some Mitas E-07 tires that I'll be testing this year.
Here's view of the 13T with 48T rear sprocket with new chain mounted to show clearances. It's a bit tighter on the rear than I'd prefer, and I expect the guide will show accelerated wear. May need to look for aftermarket sliders and guides made from harder material and with more clearance.
Note: Yes, I had a brain fart and accidentally installed the quick link clip backwards (closed end should face chain direction). I fixed it after taking this pic.
