I've got an 02' super t how low can the lower crown go? does the bottom of the crown have to stay above the mark in the stantions? or does the the top of the crown have to stay above the top of the mark? on the site, it says the mesurement from the tire to the crown should be about 173 mm, but this seems wrong, help me out

I'm thinking I need a drop crown do they make those for the 02' super?
the bike it is on is a med bighit dh, with a raceface real seal steelset

I used to have a 2002 Super T pro on my Bullit and the way I understand it was the bottom of the crown had to be at or above the line on the stanchion tube. But I could be wrong.

I'm not sure if this applies to this situation but my buddy has a big hit with a boxxer team and he bought the drop crown. Then had issues with the crown hitting the side of the frame, he now has a dent in the side of his big hit.

The top of the bottom crown goes below the milled stepdown area.
As for your measurement. I think you are misunderstanding?

The following graphic represents the formula d=t+3mm (distance=travel+3mm) which according to the graphic would give you 3mm clearance which is a minimim

Lower crown below step, upper crown above step... allow for a bit over 7" of stanchion between seal lip and base of lower crown, and all's good. And if you run fat/tall tyres, double check clearance on full bottomout, and allow an extra half inch for tyre+mud clearance... I remember another forum member (jm_ maybe?) pointing out that under full bottomout, the tyre will be taller at the top than usual, due to the base of the tyre compressing from the impact.

thanks alot, I had it switched around I thought it went above the step. now it makes sense why the bike was soooo raked

 

[Kornphlake]

the lower crown does go above the step. Under no circumstances should the lower edge of the crown pass the step. Maybe we're thinking about different steps. with the bike un-weighted there should be right around 7" between the top of the tire and the bottom of the lower crown. If you've got less than that your tire will buzz on the crown at full compression.

THE LOWER CROWN GOES BELOW THE STEP. Geez people. If it goes above the step, there will be too much leverage on the stanchions, placed at the THINNEST PART of the stanchions, and they will break.

here's a highly technical CAD rendering of what it's supposed to look like.

the crowns clamp on the fatter parts of the stanchion. Is there more than one stanchion for that year super t?


edit: well imagine all those lines were formatted the way I wanted them to be, there would be a fat section right below the top cap, a narrow section then another wide section then the a narrow section that extends all the way to the lowers.
