Just go started on fr/dh and am curious, what's the difference between dual and single crowns, and what is a crown? Thanks.
Have you been at the pirate rum again SMT? So are you also saying that single crowns are actually technically real dual crowns, like Shivers...? :skep: ( )SHIVER ME TIMBERS said:think of crowns as the cross members on the fork...hence a single crown has one connection between the two tubes (plus axle when on a bike).
Dual crowns have two crossmembers around head tube but most are really technically a triple crown fork (one above tire and the two surrounding head tube)...
only inverted forks (upside down forks like a shiver or dorados are true dual crowns-everything else is technically a triple crown)
I agree totally.rdhfreethought said:TA:
I have often wondered how much stiffer the Totem 40mm was compared to 66 (at 35-38mm) or now the Fox180 at 36mm. It would seem a simple test to measure deflection against a specific load. I know the engineers designing these forks spend many hours tweaking the designs of fork braces, crowns, etc to get good numbers (for stiffness, strength etc) that can be manufactured efficiently. But we have no numbers. The only thing we get every now and then is "8% stiffer than last year" or some other BS.
Maybe there is a German or Japanese magazine that actually tests some of these forks and holds them to their word? In the end, it only matters what rides better for a specific person, but I would bet 95% of people couldn't tell a 10% stiffer fork from it's weaker brother.
I have rode both and the Totem is probably 10x as stiff as the old Boxxer. The Totem is a far superior fork vs the 32mm Boxxers IMO.I know this is an older thread.. but here is a hypothetical that I would like answered.. as hypothetically as possible.. haha:
2004 RockShox Boxer - 178mm travel. 32mm stanchions (or was it 35mm?). non-direct 50mm stem. triple crown. 1.25" steer tube.
2011 RockShox Totem - 180mm travel. 40mm stanchions. single crown. 50mm stem. 1.5" steer tube.
Which would be stiffer. Which would be more stable.
both have 20-thru
