The thru axle stiffens the rear. A stiffer rear tracks through turns better so you have better handling. Better handling equals faster speeds through the turns.bad ronald said:It has a thru 12 rear axle and ISGS tabs for mounting a chain guide.
The thru axle on my fork is easy to remove and put back on. My Gemini has the Cannondale ovalized axle in the rear. It took me 15 minutes to line it up the first time. I can do it in a few seconds now but it's still a pain every once in a while to make sure it's lined up.bad ronald said:3 out of my 5 bikes are thru axle. I wouldn't run anything else. It takes only about 2 seconds longer to remove than a QR axle. Just spin your 5mm and the bolts are out yank on the axle and you are done.
