Good stuff!

I found this part interesting though.

'Front sprocket available in: 13, 14, 15, 16 teeth'

I don't think you can go above 14 teeth on the front, without modding the cover.

It seems as though a lot of people on the forum are happy running the 13/45 sprocket combo.but is anyone running say 13/49 or anything close to that? If so, How's it working for you? and what chain length are you using?

You can run a 15t sprocket at the front with no modification.

I have 13, 14 & 15 fronts and 42, 47 amd 50 for the rear.

I generally run 14/47 and a 108 link chain. It is pretty close to the front of the adjusters.I can run 13/47 with this chain but not15/47 I doubt you could run 13/49 on a 108, you would need a 110 link chain.

The 50t rear will not allow use of the standard chain guide.

13/50 AND 14/50 are attainable if you file off some of the plastic on the chain guide....or so I'm told anyway. I'll find out this spring when I go to mount my dirt wheels.
