2016 giant defy - sr-2 wheels

[newierider]

hi guys, i have searched the net unable to find this information for hours, but can you tell me if the wheel below is 11 speed compatible? it is from a 2016 giant defy 2 that was running 10sp tiagra. just asking as i am helping a friend and i cant get in touch with him to see if the wheel had a spacer. nor do i have it with me to measure.

wheel: 2016 giant sr-2 - hub: giant Sport Tracker Road Disc, 32h hub.

thanks guys

You could just try and install your 11sp cluster, if the lock ring won't do up, it isn't compatible.

thanks mate, unfortunately i dont have the wheel, and the person i am finding out for cannot access it at the moment, awkward! was just seeing if anyone had the wheel to tell me if it is a 11sp hub.
cheers

I'd hazard a guess that it would be 11 speed compatible (90% sure).

[Duck!]

Probably not. The easiest way to tell if it is 11-sp. compatible is if there is a spacer behind the cassette. If there is no spacer (the Tiagra cassette, unlike its higher-spec 10-sp. cousins, does not use a spacer at all) then it will not fit 11-sp.

Discovered two days ago my 2014 P-CRX1 does have a spacer so 11 speed.

thanks mate but thats quite an old wheel, its an old ad. i saw it too earlier and im pretty sure your crx1 has a different hub. thanks again though.

sorry duck, trying to understand what you said.. i get that if theres a spacer, its most likely 11sp compatible, but what are you saying about the tiagra cassette? any 10 speed shimano cassette could be a tiagra cassette right? therefore needing a spacer..

No!. Tiagra cassettes will be labelled either CS-4600 or HG500, depending on exact vintage. These are characterised by the shallow spline used on virtually all Shimano-pattern hubs. 105, Ultegra and Dura-Ace 10-sp. cassettes (CS-5600, 5700, 6600, 6700, 7800 & 7900) have a deeper spline except on the smallest sprocket and are shorter through the centre of the cassette, designed for Shimano's short-lived 10-sp. specific freewheel body pattern, which very few other manufacturers adopted. The narrower cassette core dictates that a 1mm thick spacer is required (and supplied with) those particular cassettes when fitting on a 8/9-sp. pattern hub. Therefore, when fitting those cassettes to an 11-sp. hub, two spacers will be required. 4600/HG500 cassettes do not use the 1mm spacer.

..wow. blown away by your response. I would say you know your stuff but thats an understatement! Thanks so much duck! Really appreciate your time. Cheers!

It makes you wonder why any manufacturer would bother making a 10 speed only cassette body (in the last 5 years) because its it locks the buyer into 10 speed (and makes upgrading to 11 speed a PITA) and is solvable with a 1mm plastic spacer if the wheel does use a 10 speed cassette (or equivalent width cassette). Furthermore they only have to tool/manufacturer one size of cassette body (not 2).

To the best of my knowledge it's getting close to 10 years since anyone - Shimano included - has produced a dedicated 10-sp. hub. Since the introduction of that spline pattern in 2003 (for '04 model year), I believe even Shimano began phasing it out within five years. I possibly suspect that SRAM choosing to design their cassettes to the "regular" 8/9-sp. longer, shallow spline pattern contributed to its lack of adoption in the wider industry.

Upgrading to 11 from dedicated 10-sp. is no less of a PITA than it is from upgrading from a 8/9/10-sp. hub - few hubs are readily convertible. And it's not a plastic spacer - such a thing would squish & shatter the first time the cassette is tightened against it.

I've had few plastic ones Duck and they haven't squished (Giant wheels come with them, getting back on topic). [edit: removed unnecessary jibe, sorry] - went and checked my "plastic ones" and they weren't 1mm they were more like 3mm, so I stand corrected.

[Duck!]

The 8/9/10-sp. conversion spacers on 11-sp. hubs are aluminium or steel - I've not seen a single plastic one (but I have seen plastic spacers intended to separate the sprockets used in place as a conversion spacer, with destructive - to the spacer - results). The 1mm spacer supplied with cassettes that need it is always steel, and I've even seen them get deformed!

thanks for all your help and advice guys. turned out the wheels did take the 11sp.
