I did the 606's with a 14t also, makes it so your can really crawl in 1st gear if you want/need to and also makes 2nd gear a little more usable in tight woods (for me) as well as quicker acceleration in all gears. Obvious downside is top speed suffers somewhat and the speedo seems way
out of whack now, wondering if anyone with this setup and a GPS could test the accuracy for us. I have seen a 12 O'Clock Labs electronic speedo calibrator (saw it at Wheeling Cycle) that would be able to correct any speedo problems caused by tire and/or sprocket changes. Anyone tried one of these?
