So I'm in the process of building up 2 different bikes. I've been wanting to be a lot more hands on, and do as much as I can myself this time around.
First Bike: KHS Aero Track
I purchased a Campagnolo Record Pista crankset and a Phill Wood bottom bracket. This is the first time I ever tried installing my own bottom bracket and crankset. The adjustable cups threw me for a bit of a loop, and I only had 1 Phil bb tool to use. I kept adjusting, but either the inside of the spider hits the chainstay, or the non drive side arm hits the stay.
This is how far out the bottom bracket cup had to sit so the spider had clearance.
Except, when the cups are positioned like that...my left crank arm hits. And it's not even close, it hits by quite a lot.
I chalked this up to user error. I've never installed a bottom bracket before, let alone a Phil Wood bottom bracket. I had installed the crankset 3 times, after continuously adjusting the bottom bracket cups. There might have been a sweet spot where I'd get clearance on both sides, but I got annoyed. I ended up ordering the Campagnolo Pista bottom bracket, so I can take that out of the equation. It's fixed, and there's only one way to install it. No adjustments. I'm hoping it works.
Second Bike: Cinelli Vigorelli
So, I have everything ready for this build. All I have to do is buy a chain, adjust the headset, and throw some tape on the bars. But...dun dun dun...issues with the crankset...again.
I got the Miche Primato crankset with the Miche bottom bracket. So they are matching, they're meant to be used together. Same thing happens. I installed the bottom bracket, then installed the crankset. The more I tightened the crankset on, the closer and closer the spider got to my chain stay. I stopped right before it ended up hitting. Like, you could probably slide 1 or 2 pieces of paper in between the gap. However, because of the flex in the frame, when I sit on it and spin the arms, it starts rubbing.
Here you can hear it rub. It's only 1 out of the 5 arms of the spider that do it too.

This one I'm also chalking up to user error. I'd rather blame myself and think I just did something wrong, than admit the crank won't work with my frame. The Miche bottom bracket is 107mm. Would getting a 109, and adding 1mm to each side allow enough clearance, while keeping the chainline a safe distance?
I'm just really confused, as I've owned 4 bikes in the past, and none of them have ever had issues with chain stay clearance. I've even owned another Vigorelli before, and had a cheap Eighth Inch crankset on it. The issue isn't the size of the chainring, as that's not hitting, but the inner part of the spider/chainring bolt area itself.
Any help, suggestions, ideas would greatly help. I plan on taking the Vigorelli to a local bike shop, but I honestly don't know how much I trust the "fixie" shop's knowledge around here. I've had bike shops do some strange things to my bikes in the past.
Also, if it comes down to these cranksets just not being compatible with the frames...how do I know what will work? Short of spending the money to buy a crankset, only to have a failed installation, then have to try and return or sell them afterwards?
Thanks
