I have a few questions that I hope somebody can help me clarify. Who in winnipeg can press my old sprockets off the drive axle and press on the new extroverts, as i am assuming this can't be done at home? and I was wondering how effective these things were and the advantages of having them on a sled?
Thank you

Your dealer can press them on, just be prepared to pay for around an hour's worth of labour. If you have access to a press you could try it yourself, there's not that much to it. I had Rene's do mine...took them a couple tries, but they got it. Should be no problem for them to do yours now if you decide to go that route. lol Basically extroverts allow you to run the track much looser without it ratcheting (looser = more power). Some say that there are weight savings to be had over the traditional 4-driver setup, but the extroverts are pretty beefy so I don't think there would be much weight savings to be had over 4 standard drivers. (I meant to weigh mine before they went on the shaft and forgot to, whoops.) If you're thinking about putting them on the sled in your signature, just be aware that you might have to trim the rail caps and possibly the tips of the rails to get enough clearance.
