Duck's Tech - Compatibility Notes, the SRAM version
Postby Duck! » Sat Jun 27, 2015 12:43 pm
Drivetrain:
Let's start with shifters & rear derailleurs. Despite using terms such as "1:1" and "exact actuation" to describe their leverage ratios, which logic would suggest are the same, they're not, and that cuts down the compatibility from what you'd think. 8 & 9-sp (MTB only) are identified as "1:1", so any combination of those will work. For 10-sp, SRAM tweaked things to "exact" actuation, which does not play with 1:1. On the plus side, road & MTB 10-sp, plus 11-sp road all use this "exact" ratio, so it's easy to cobble up mega-wall-climbing transmissions using a 10-sp. MTB rear derailleur with either 10 or 11-sp. road shifters. It's also possible to do a budget 11-sp upgrade by only replacing right shifter, chain, cassette, and ensuring freehum compatibility. MTB 11-sp. is different again, and limited to its own family.
There are/were a couple of models of Shimano-compatible shifters, named Rocket and Attack, which were either 7 & 8-sp, or 8 & 9-sp. In any case they're uncommon. Aside from these models, there is no compatibility with Shimano shifters & rear derailleurs.
At the front, derailleurs are all cross compatible, including with Shimano.
All chains & cassettes except for MTB 11-sp. are designed to Shimano standards, so are completely compatible, except they all use the standard shallow spline, so will not fit on the short-lived (and uncommon) deep-cut 10-sp. specific freehub that Shimano and a very few other hub manufacturers adopted for a while. Cassettes beyond the range of their full groups are produced - down to 7-sp. for MTB & 8-sp. for road, offering alternate ratios to those produced by Shimano. MTB 11-sp. cassettes use the same sprocket spacing & cassette width, but due to the use of a 10T top gear require a special freehub body. All major wheel manufacturers except Shimano offer this as an option, and is available as a replacement part for conversion.
Cranks, as pointed out in the Shimano thread, are not fussy, but it is perhaps worth pointing out that the GXP spindle is not compatible with other external bearing or press-fit bottom brackets, due to it stepping down from 24 to 22mm at the left end.
Brakes:
Standard compatibility rules apply in this department; road levers will work with any standard calipers, although some later Shimano models may not perform optimally, also cantilever, road mechanical disc or mini-V-brakes can be used. For MTB mechanical brakes, standard V-brake levers will also work with all MTB cable disc brakes.
Hydraulics I'm not sure about road/MTB compatibility. Given the noises they were making on release of the road models about being tuned for more modulation than MTB brakes, I suspect that lever/caliper cylinder ratios may differ and not offer the best possible performance if mixed. Do not under any circumstance mix SRAM components designed for use with DOT brake fluid with Shimano, Tektro/TRP or any others designed for mineral oil.

*Unless fitting to an 11-sp. compatible wheel or Mavic hub; in both cases the necessary spacer is supplied with the wheel.

Ah, so Shimano 10sp cassettes are still built to fit the 10sp hubs?Duck! wrote:No spacer is required*, because the cassettes are built to the 8/9-sp. spline standard, rather than the Shimano 10-sp. specific (no longer produced) design, which actually used a shorter freehub body.

You sure on this? My adventures in Shimergo always steered me clear of sram derailleurs as they didn't offer any compatibility. I ended up using campy 11s shifter with ultegra 6700 for Shimergo heaven.2wheels_mond wrote:Worth noting as well for drivetrain that a Campagnolo 10 speed shifter will work with a SRAM 10 or 11 speed rear derailleur and a 10 speed Shimano/SRAM cassette. Not sure if that applies to 11 speed too.

Dura-Ace, Ultegra & 105 are, Tiagra is not, so that doesn't need the little spacer either.queequeg wrote:Ah, so Shimano 10sp cassettes are still built to fit the 10sp hubs?Duck! wrote:No spacer is required*, because the cassettes are built to the 8/9-sp. spline standard, rather than the Shimano 10-sp. specific (no longer produced) design, which actually used a shorter freehub body.

I've not tried it personally, but there's a bit of evidence around of it working:Jesmol wrote:You sure on this?

Snaffled a great wheelset for the Cannondale Slate. Only potential snag is that it has an XD Driver fitted.
I can get a replacement freehub to get it to Shimano, which is probably the preferred option, but can't seem to get my head around what cassettes are available for the XD Driver.
Currently run a 11-34 HG700 cassette (11sp), and from what I can gather, the smallest XD cassette is 10-42.
Is that correct ? Any other alternatives ?

For 11 speed cassettes on an XD driver, the only choice from SRAM is 10-42, unless you go for an outrageously expensive boutique option like 3T or Leonardi.MichaelB wrote:Hoping someone can help.

That's what I seemed to find, although it was hard work.
Seems like a new freehub is in order. Or a bit more investigation re 1x, but that's not the likely option.

Just out of curiousity, looked them up as it may make sense rather than the cost of swapping the driver.2wheels_mond wrote:....unless you go for an outrageously expensive boutique option like 3T or Leonardi.
EEEEK
The Leonardi one , 9-36 is reasonable at €230 + shipping, whilst the 3T 9-32 is a measly €270 odd + shipping.
Faaaaaaaaaark
Even if VAT has to be taken off
