Are These Zipp 303s, 11 Spd Compatible?

Xcessiv

I'm shopping for 303s. According to the decals, do you know if these ones are Shimano 11 spd compatible? The owner doesn't know.



Thanks!

Decals look right (no "Speed Weaponry" tag line). Hubs look to be the right colour. I cant tell if the drive side lacing is radial or crossed; if crossed, those are V9 hubs and definitely 11-speed. If radial, then if the non-drive-side end-cap is black, then the wheel should be 11-speed (at worst you'll just need a new freehub, about £100). If it's red or blue (Shimano or Campag respectively) you'll need a replacement axle and the wheel will need redishing. The conversion kit is about £140; I just did my 404s; took 20 mins.

DS is radial

In that case they're (2013) V8 hubs at best, or restickered (2012) V7s (prior hubs are silver). The V8s will be native 11-speed (with a black NDS end cap); the V7s will have a red end cap and need conversion. The 11-speed Shimano freehub does say "11-speed" on it, so it's not too hard to tell...

Thanks! I'll look for this. By the way, nice nickname (964Cup).

Hello Xcessiv
Do you now the serial no of the wheels?

I had the same ones. Looks like you'll need a new axel installing and the wheel re-dished.

Or do what I did

Buy a campagnolo 10 speed freehub which is a straight swap with your current. Campagnolo 11 speed cassettes fit on their 10 speed freehub (unlike those prats at shimano) and shimano 11 works perfectly well with campagnolo 11 speed cassettes.

Sigma quoted £200 for the new axel etc but the new freehub cost me £30 and an 11 speed campagnolo cassette £50. And apparently they last ages longer than shimano ones too.

The conversion kit is £147 on Amazon, of all places. http://www.amazon.co.uk/gp/product/B00A ... ge_o08_s00

Lightweight Campag 11-speed cassettes are not cheap; for example the cheapest Super Record 11-29 that I can find is £264 at Wiggle - the equivalent 11-28 SRAM Red 22 (XG1190) cassette is £100 cheaper (at CRC). Dunno where you found a Campag cassette of any type for £50 - even Chorus is £79. The XG1190 is 130g lighter than the Chorus cassette (and also about 60g lighter than Super Record).

I also have no idea where you got a Zipp Campag freehub for £30, not new at any rate. They're about £88, and that's without the correct Campag NDS endcap, which is £12. So I make it £88 + £12 + £79 for a freehub, endcap and cassette, or £179. £179 will also buy you the conversion kit and a 105 5800 cassette, so it's a wash.

Campag 11-speed is also not a perfect match for Shimano indexing (pitches of 3.85 vs 3.74)- it's close enough that you don't need to worry for the rest of the stage if it's a replacement wheel from neutral service, but I'm not sure what the wear would be like over 000's of KM, especially if you spend a lot of time at the top or bottom of the cassette (where the pitch variance will add up, based on centre-cog indexing).

On the other hand, if you think I'm talking bollocks (it's happened before), I happen to have a complete Campag axle assembly going spare, including the endcap, axle and freehub with lockring for Zipp 188 V7 hubs like those on the pictured 303s...

I bought it all used, I wouldn't ever buy any of that stuff new. Chorus cassette was boxed and new off ebay.
