Measurements?
 

How do you measure your chainstays and seatstays? Do I measure from the BB to the middle of my axle slots or what?

Presumably, i'm not sure really

Middle of the bb, to the middle of the dropouts.

It's kinda hard to get it 100% accurate, but i'm pretty sure that's how you do it.

I would guess that the GT website would have the specs on your frame on their website, try there first...

I did that, but it says 410 and it doesn't say in what. And if it was mm it wouldn't make sense because my chainstays would be like 16", which isn't right.

Chainstays on race bikes are mega long. For stability

I would say it's like 14" or 15"

16" is pushy though...

I kind of measured it before I knew exactly how and I got like 14, so it shouldn't be much longer than that.
