Finally got one of my Tarmmac up and running temporarily... it was nice to finally get out to ride. Waiting for one more part to fix the Tarmac,The part I am waiting for should be in by the end of the week. So I will ride the bike as is until then. I will be replacing the bottom bracket with a conversion BB from a Praxis to Shimano Hollowtech. I changed out freehub from 10 speed to 11 speed, new cassette and chain, was hoping this helped the chain hopping, no luck, tightened up existing bottom bracket, no luck. Too much flex on big chainring. The Scott Foil bottom bracket shell opening on non-drive side stretched .45mm so bottom bracket I received won't fit. I contacted Scott Bikes, they are seeing what they can do for me. I was initially told to try and epoxy the BB to fit or get a custom made BB to fit. I told the person I was speaking to, "Whatever caused it to stretch that much is a problem and what is to stop it from continuing or having a catastrophic break, that wouldn't be good!" He said, I was right... I will call them back today because he was supposed to get back to me this past Thursday or Friday. Wish me luck.
