According to the website, the BB drop of the Felt Tk2 is 55mm. Same as the Felt TK1.

I know you asked for BB "height". Here is an article explaining the difference between the two terms:

so knowing the bb drop is there a way of working out the bb height by working out the diameter of the whell and subtracting the drop from it?

Yeah, assuming you're on 700c's, your BB height would be the radius of your wheel minus the BB drop.

622mm - 55mm = 567mm (without a tire)

assuming you use tires on your bikes, it will be higher.

567mm bottombracket drop would be as long as most peoples top tubes, Comeon son..

Measure your wheel height with tire on and inflated.

Half of that.

Minus bottom bracket height.

Hope that helps.
