So I got the Risse Racing flat crowns for the 888r. I know there has been some interest in these so I thought I'd post the results.
The set up I have is:
2003 Bullit, King steelset, 200mm 888r, and 26" wheels front/rear.
I've got the lower Risse crown set about an 1/8" up from the MIN line on the fork leg. I put it all together and the top crown sits right at the top of the fork legs (perfect fit-any longer stack height and it wouldn't have fit). My stack height is 6 3/8".
With the new crowns the height of the top tube-right behind the head tube-is an inch lower….good enough for me. Just put them on so I haven't had a chance to ride it yet. The GOLD crowns look dope.
