You mean the Avid Arch Extreme?
avid arch extreme they are.
here's a comparison picture for the record.
extreme's on the right.
supreme's on the left.
anyone care to give reviews on either.
or which they prefer?
i wouldn't mind putting a set of extreme's on something.
I think this upper comparison picture is mine
but I won't claim copyright
I was lucky enough to get hold of some supremes and extremes a few years ago
They are indeed superb and I d rather say the best v brakes ever manufactured and beautiful as well - form and function at the same time
two tiny issues with these brakes
the springs - you will notice on my pics that the extremes have actually one spring on each side
probably a bit more durable than the complicated one spring of the supremes ( you could probably redo a extreme spring with piano wire - for a supreme that would be extremely difficult)
so they are interchangeable as long as you have the springs for each design
the second issue is the stop of the spring - they were actually in plastic ( they have a thread and are slightly prone to cracking) I had to have some tiny stops machined in aluminium to have my second set working
can't really say if they are very much different in efficiency - as the design is close, I'd say they are equal - but the supremes are better looking
the supremes sit on my serotta max 853 and the extremes are on a specialized s works steel 1995 ( know its not period stuff but don't care
one of each will go to each of my two sons on my will -
I won't sell ever even in my wheelchair
