DT Swiss RWS Thru Bolt
Hi guys,
This should be a quick one... Looking at stiffening up the rear on my Scott Scale hardtail (carbon version) so I was going to convert my DT 240 hubs to the 10mm thru bolt.
Only there's so many options that I thought I might just double check before I order the wrong one.
The thru bolt comes in 135 and 150, fairly sure I need the 135, which is the width of the hub but then what would the 150 version be for?
Here's a link to the bolt and kit, if anyone who knows this stuff could have a quick look I'd be forever grateful.

Thank you

I have the DT SWISS thru bolt on my 575. It certainly makes a difference to the stiffness in the rear end, and you will really notice it most on rocky or corrugated trails.
I went the 150mm version as it gives you a litle more Length to get the nuts on the end when looseniong and removing the wheel. 135mm will fit most bikes but may be a tight fit, with little scope for loosening the nut.
I also have DT swiss 10mm thru bolt in my Jamis, it is a good mod and am pleased with the added stiffness, I have the 135mm .
Wouldn't the 150mm version be for 150mm hub spacing? i.e. on a free-ride or DH frame?
... so will go with the 135 then.
I'm guessing it's only called 135 (as in for 135 hub) and not actually 135mm long as that wouldn't leave you anything to tighten it up...
this is the part that i find confusing.
the 142 X12 Bolt through on my ASR5C, stiff as which is awesome.
as far as i know, i can only fit the 10mm in my standard dropouts
shame, because there is a conversion kit to 12mm for 240 hubs...
still a bit confused about the length thing but the 150 doesn't seem to ever be in stock anyway.
If you have a 135 hub you get a 135 axle, if you have a 150 hub (mainly on DH bikes) get a 150 axle.
Dicko said he has a 150 axle on his bike but technically speaking a 150 axle shouldn't fit a 135 spaced frame due to the fact that the threaded portion of the axle shouldn't extend far enough in too tighten and i'm damn surprised it does. If I'm wrong and it does it's pretty crap engineering because a threaded portion shouldn't be bearing load through the drop out on a 150 spaced bike.
Edit - the 10mm is a world of different from the QR
Maybe I have mislead you - I have a 135mm hub on the Yeti 575, but the total length of the bolt is 150mm (length of shaft including thread) i.e enough length to protrude thru the hub and get the nut on the other side.
I check my old order from CRC and I definitely purchased the DT Swiss Wheels QR RWS Thru Bolt 10/150mm Rear.
Hope this helps.
135 it is for me.(I hope)
this is by process of elimination... my hub is 135.. there's only two bolts available.
if a 135 hub would require a 150 bolt, there wouldn't be a bolt for a 150 hub.
my guess is the dimensions refer to the unthreaded part of the bolt/axle.
anyway,put the order through last night. I'll let you know if it fits.
cheers

and spacers for my butcher, went in a charm.
Just to clarify for the old fashioned XC guy. Is it a case that with the right hub you can use a 10mm through bolt with any frame to give additional stiffness?
A ”standard 9mm” qr is the size of the end cap that fits in the drop out, the axle it self is much smaller.
Plenty of current hubs can do the change because most of them have a larger internal axle diameter to support the bearings. I don't beleive it's as easy with cone bearing hubs.
Before you take the plunge check the drop outs in the frame and also with the frame manufacturer then check the hubs. No point in checking the hubs if the frame won't support it.
"The thru bolt RWS optimizes the RWS system even more. Instead of a regular 5 mm quick release axle, a 10 mm rear thru bolt is used. Together with a DT Swiss thru bolt hub it offers an even better connection to the frame and fork than even a standard RWS as well as any other quick release. The RWS thru bolt system combines the advantages of a fixed thru axle with the ease of use of a standard quick release. The RWS thru bolt system is 100 % compatible with any standard frame or fork that would normally use a quick release!"
most of the DT hubs are convertible.
9mm thru bolt for the front - 10mm for the rear. there's still a little discussion going on about the correct length (see above).
i'm new to this as well, will report back when i get my 10x135 next week....
