Converting DT Swiss 240s from 135 10-sp to 142 11-sp

[dolface]

Looking for a sanity-check that to convert my DT Swiss 240s ratchet hub from 10-speed 135mm QR to 11-speed 142mm thru-axle I need endcaps and this freehub: HWYAAX00S3188S (based on the docs here (http://www.dtswiss.com/Resources/Support/TECH-SPECS/Techspecs_ROTORKITS_MTB-en.pdf) [PDF warning on that link])

Any tips or tales would be much appreciated!

You might need to re-dish, but some people don't even bother.

I assume you're talking about Shimano 11 speed road cassette? The doc you linked to is for Sram's 11 speed mountain.

If you're talking Shimano 11 speed road then it's not as easy as you're hoping for. The 11 speed freehub body needs an 11-speed-specific 142x12 endcap for the driveside. The 11 speed endcap is 1mm longer than the 10 speed endcap and without it the cassette lockring will rub against the frame.

To the best of my knowledge DT Swiss do not sell this driveside endcap. You can buy a hub with the 11 speed freehub and 142x12 endcaps, but that endcap can't be purchased as a stand-alone item or packaged with a freehub. I'm guessing this will change in the future.

You could buy a 350s hub with the 11 speed / 142x12 kit and swap the freehub body and endcaps with your 240s hub.

The wheel will need to be redished 0.5mm to the driveside.

On some of the earlier 240s hubs the axle needs to be replaced as the internal diameter is slightly less than 12mm. Again, the 350s will fit.

This is what you need for the conversion:

Assuming your 240s is 12mm ready, as early models (pre 2010) had a 11.5mm ID axle. The above item has the right thru-axle end cap but you will also need a left side cap as well, which you can get for this following link. Unfortunately it will come as a set so you will end up with an extra right side cap.

If your 240s has a 11.5mm axle then you will need the following kit:

http://www.ebay.com/itm/DT-Swiss-240s-340-440FR-Rear-Hub-142mm-x-12mm-Conversion-Kit-TA-Adapter-142x12-/151370788197?pt=LH_DefaultDomain_0&hash=item233e66ed65

As for the swap, just pull the cap out on each side, the freehub will slide right out and the ratchet will expose. Make sure not to loose the spring. The replacement items should snap back in with hand pressure. Pull the caps off can be tricky because they are short without too much lever so you might wrap a rag round with a plier or vise grip and pull them out.

As for swapping the axle, it will take a little bit more work and I am not sure if I can describe it here in detail but it should not be hard to tap it out from the drive side.

Thanks for all the responses, I think I'm set!

That freehub body will only fit a mountain bike 11 speed cassette, not a road one.

[dolface]

Thanks, I figured that out and got the road one.

Where did you get / will you get the 11 speed road specific 142x12 driveside endcap? I don't see them listed as an individual item anywhere.

[dolface]

I bought this http://www.competitivecyclist.com/dt-swiss-240s-freehub-body?s=a(they sorta-price-matched) and I hit up the live chat to make sure they were going to send the correct endcap so we'll see.

I also got this http://www.ebay.com/itm/NEW-DT-SWISS-12-X-142mm-12-X-157mm-Thru-Axle-End-Caps-240-350-Tricon-142-157-/111475738362?pt=LH_DefaultDomain_0&hash=item19f478c6fa because I need a left-side cap as well.

Hopefully it all works out but either way I'll report back.

[tristan]

I'm sorry but it probably won't work...on most frames the cassette lockring will rub against the inside face of the dropout.

You need the 11 speed specific 142x12 driveside endcap - it's 1.0mm longer than the one you've ordered.

[tristan]

I thought a photo would help explain. The 11 speed road endcaps are 17mm long - the 10 speed road, 11 speed Shimano-mountain, and Sram XD endcaps are 16mm.

You need an endcap marked "11 speed road" for that freehub body.

[dolface]

Thank you! I'm into new territory here and sorta feeling my way.
Competitive Cyclist assured me that they were sending the correct drive-side end cap for 11-speed road, I bought the set I linked to on eBay just for the left-side one.

Are you saying that I need a different one all together?

[Dead Man]

Are you converting DT Swiss 240 Shimano 10 to Shimano 11?

The 11-speed road TA end caps should be HWGXXX0003525S. These 11-speed road caps have been available not long ago so you can get them now. I have been using the DT Swiss MTB TA end caps with 11-speed road cassette from day one without a problem. I even created my own TA end caps for Campy 11-speed. It has been a while since I measure the freehubs between 10-speed and 11-speed but I remember the 11-speed freehub had a shadower recess. Nonetheless, the DT MTB TA end caps should work fine with a Shimano11-speed road cassette without any rubbing of the ring. There is technically a small offset on paper but in reality it is virtually undetectable.

[dolface]

Trying to anyway :)

Are you converting DT Swiss 240 Shimano 10 to Shimano 11?

[Dead Man]

I did not realize you could do this....

I just did a 240s Campy to Shimano 11 conversion, which is really simple.... if you had a campy cap on the non-drive side and the cap/freehub conversion on the drive side, wouldn't that achieve the exact same effect? (maybe that's exactly what you're trying to do/we're all talking about?)

[dolface]

I don't know the answer to that, but I don't think Campy has 12x142 TA options yet?

[Dead Man]

12x142 TA options

I don't know what this is, so we've rapidly hit the brick wall of my ignorance....

[dolface]

Sorry for the jargon, the bike these are going on uses the 12mm x 142mm Thru-Axle standard so it needs end caps that can accept a 12mm thick axle.

Ah... no wonder none of this is making any sense to me.

I'll just slip out the back.... forget I was here :)

Did this ever work? Based on my research and dt swiss tech support, these are the parts required for the conversion:

11speed road freehub:
Shimano 11 road
HWYABX00S2775S
FW-1916
DT-0427
36070

11speed specific thru-axle end caps
12 / 142 mm for Ratchet Shimano Road Rotor
HWGXXX0003525S
HU1372
DT-0549
370471

If you want to do thru-bolt, you'll need:
10 / 135 mm for Ratchet Shimano Road Rotor
HWGXXX0004634S

Yes, this is a very simple, very common conversion these days. I just did it to 4 wheel sets of mine.

You need 11s end caps and an 11s shimano road freehub, just like you listed above. There are no campy T-A end caps as far as I'm aware.

Also, as far as I am aware there is no re-dishing is necessary with ANY DT conversions, its all end cap magic.

[kfreytag]

Seconding what eAUMANN said. I've done this to a pair of ENVE XC 29'ers, going from 10-speed QR to 11-speed 142 thru axle. The new end caps are what you need, though getting the old ones off the front can be a real PITA.

[foo_fighter]

Anyone have a good source for all of these parts? It starts to add up if you want to mix n match.

It certainly does.

Caps...$34 shipped (http://www.ebay.com/itm/DT-Swiss-12x142mm-Thru-Axle-End-Caps-for-11-Speed-Road-2011-180-240-350-hubs-/182181359191?hash=item2a6adaee57:g:MYIAAOSwNuxXa-w6), $78 freehub here (http://www.ebay.com/itm/DT-Swiss-Aluminum-Freehub-Body-Shimano-11-Speed-fits-180-190-240-350-440-hubs-/201345201948?hash=item2ee11bf71c:g:GREAAOSw-KFXdvfy).

A few tips:

1 - getting off QR caps - use an old j-bend spoke with some vice grips clamped onto it. feed the head of the spoke into the skewer hole and hook it on the inner edge of the cap, then pull firmly, alternating the location of the hook if necessary so the cap is getting pulled off relatively straight.

2 - when installing new caps, particularly T-A caps (which are much harder to remove) - GREASE THE EVER LIVING SH*T OUT OF THE AXLE AND INSIDE OF THE END CAP. Seriously. Lots of grease. Too much won't hurt but too little and you'll be hating yourself when the day comes that you need to get em off again and you have to resort to clamping vice grips onto the cap, marring it up and ruining your gorgeous hubs stealthy black aesthetics. That is all.

And if they do get really stuck (like mine did), you might have to resort to a pipe wrench to get a grip on the axle.

This is incorrect - the move from a Shimano 10 or Campagnolo freehub body to the Shimano 11 freehub body will need a 0.5mm re-dish. That's obviously not very much and probably wouldn't be an issue to many people, but it does exist.

Another tip: The non-driveside QR endcap usually comes off pretty easily. Once the non-driveside is off you can put a long 8mm hex key (or something similar) into the axle of the hub and tap it with a hammer to remove the driveside endcaps. Just be careful that when you tap your freehub body and springs don't go shooting across the room ;-)

K, just speaking from a ton of practical experience swapping freehubs like a madman between many wheels, I use campy and shimano cassettes and their respective freehubs across 8 bikes, never had a single dish-related issue.

Like I said it's only 0.5mm so unless you check with a dishing tool you're unlikely to notice and depending on how fastidious you are you may not care.

One of the great things about the higher end DT hubs is their ability to be converted so easily...we've built Campagnolo disc-brake wheels, single-speed hubs with 142x12 axles, 10x135mm thru-axle...you name it. They're fantastic hubs with excellent durability.
