DT SWISS Africa: Tech Q&A

[MarcHD]

I don't believe he says its not achievable, more that most people don't tighten it that tight.

I tighten my X-12 by with a multitool to higher than 11N.m.

The RWS skewers that are fitted to my Road PRC 1400 Spline wheels also achieve enough clamoing force. I just feel so comfortable tightening them so tight as the bike has carbon drop outs. But they're tight.

He also refers the ideal tightening torque for an M12 thread being much higher than 11N.m which is very true when consulting tightening torque tables. For Aluminium bolts in M12 its in the region of 28N.m, twice the tightening torque of a thru axle.

 

can I ask if its possible to return to a cam type clamping device? One of the annoying thing about TA's is that thing has to be done up flippen tight or it comes loose with time, especially the rear. Not a problem specific to DT, more other brands TA.

 

Fair enough, this is true!

 

I can tell you DT won't be changing to any cam system anytime soon as their RWS technology has stood the test of time which is why it is by far the most popular skewer found on bike brands using OE products from DT such as your YT.

With their removable "plug-in" levers now available more recently (including here in SA) the option to remove the lever and tighten the skewer to higher/correct torque levels is even easier.

Is that skewer also available  with the lever permanently fixed in place like the RWS QR 5mm skewers?

yes we stock both the plug-in and standard "fixed" lever models.

 

Stock is up and down at the moment, but if we don't currently have, be sure we will always have on the way.

Hey guys,

 

Just a reminder about our ongoing consumer poll, in which you can have the chance to have your thoughts known on the current state of DT Swiss in your market.

 

If you have just a few moments, we would be hugely grateful if you can complete our poll linked below.

 

There is no sign up, no emails gathered with which to spam you. Just a simple and easy to complete questionnaire that will help us improve and better serve you!

Thanks for your time, and continued support!

I hear you, but am going to try out the SKF's first and if they do not last, then will fall back on to the DT's.

 

The rear on the YT is rather "chunky" and under sprinting loads it certainly feels as stiff, if not stiffer than previous bikes I have owned.

 

 

 

I would run Deep Groove bearings without a problem.

 

In my opinion bearings in bicycle applications are operating no where near their design limitations. When designing a bearing application, 2 of the most important factors to consider (besides size of course) is the static and dynamic load capability, these are specified on the bearing data sheet and on lots of these small bearings, loads are above 500kg and no where near what they will experience on a bicycle.

the other is max design speed like the load these bearings can handle 12000 rpm in grease and higher in oil - once again no where near the speeds experienced on a bicycle.

 

Angular contact would be better to cater for loads experienced off the vertical when cornering, but once again, considering the design parameters and the application a deep groove will never fail.

 

99.9% of bearing failures are due to - Lack of lubrication - ingress of moisture (main reason) - ingress of dirt - operating beyond their design limits (very uncommon)

Service your bearings 4 x year - clean - repack with grease and you will never have to replace them.

I beg your pardon!

 

1. "other is max design speed like the load these bearings can handle 12000 rpm in grease and higher in oil - once again no where near the speeds experienced on a bicycle." I spin that with a 36t chainring and the nice 9t on my E-Thirteen Cassette all the time.

I thought so. These things will explode on my first ride!

Now that we've calculated your cadence - If you let us know what you and your bike weigh we can calculate how many G's you pull through those berms

that is a low blow to the bottom bracket!

this looks good?

I finally got my act together a few weeks ago and had Black Sheep Bikes sort out the bearings for me .. turns out it was just the f/hub bearings and BSB took care of business ... including making a custom tool to remove the outer race from the shell as the rest of the bloody bearings had blown apart.

 

So all is good in the world now ... then it took me another week or two to get a gap between work and life to fit the rotor again and check everything ... the YT feels good to be rolling again and just feel right.

Great stuff......what happened to one of the most knowledgeable & experienced wheel builders in Africa....Doug Patterson ? Sure you guy can get him to assist. #getdougback #dtswiss

Hi Marc

I have a set of 350 hubs with a microspline free hub. The other day I noticed that when the wheel is removed there is axial play on the free hub. Once the wheel is clamped in place this stops as the end cap is pushed tight.

 

Is this normal?

 

Thanks.
