Upgrading Wheels on Road Bike with Discs

Hello everyone,

I have decided to upgrade the stock wheels on my Giant Anyroad, most probably to the Campagnolo Zonda C17s.  I understand that I need to choose the 6 bolt QR version so that they are compatible.  But I am wondering if there is some sort of width measurement for the hub that I also need to check?  I mean, the discs on these wheels obviously have to align perfectly with the break calipers that are on my bike.  Is there an industry standard width of hub so that the disc and caliper are guaranteed to align / fit?

Many thanks

If they're QR then they'll most likely be 100m front hub spacing and either 135mm or 142mm rear. Pretty much any wheel with a QR (rather than a thru-axle) should fit. The width will be listed as the OLD (over locknut dimension) and is sometimes referred to as spacing.

You don't necessarily need to have the 6 bolt version, centrelock will be fine too unless you want to swap over your existing discs.

When searching just make sure you don't buy wheels with Boost spacing (a wider MTB standard) or thru axles (which will either be 12mm or 15mm). Sometimes you find bikes/wheelsets with thru-axle fronts and QR rears.

That's very helpful, thanks a lot.  

I don't know why, but I always thought there was something about my frame that required my to buy wheels with the 6 bolt connection, but now that you mention it, it's quite obvious that if I'm buying new wheels and new discs, the only thing that matters is that both the wheels and the discs use the same system (6 bolt or centre lock).  Thanks again!

Disc rotors are fairly cheap so if your preferred wheels are centre lock then it's probably not a deal breaker. Zondas have many fans, but these were well reviewed recently too: https://road.cc/content/review/prime-baroudeur-road-disc-wheelset-272611

Thanks mate.  They look good, and are quite a bit cheaper than the Zondas so will definitely consider them.

I see that they come as thru axles as standard but the QR adapter is very cheap too.  It seems as though that could be a better way to go, because when I buy a new bike it is more likely to have thru axles, so I could keep these wheels and use them with the new bike too.
