You need to go to Carmel lol, there's a couple of good shops off the trail north of 96th. They have a ton of bike shops. BGI has never been helpful for me. There's a good shop I buy parts from on the NS off of 86/82 across from Target behind the jimmy johns. It's in a basement basically. Good prices, killer service and it's right off the trail. I think its called DG.....can't really remember. Other than that my buddy is unloading a fixie, not sure what you are looking for but it's priced well and it's in Lawrence, just a thought, no fowl in seeing if it fits. I'm on the south side...
