road disc brakes

Re the lockring slaw, what type of axle do you use? I'll be using QR, it seems the lockring issue is only when using the thru-axle adapters, from what I read in the reviews at http://www.this link is broken/au/e ... prod143360 for example.

These wheels are under $400 in PBK's wheel sale with the ITK10 code added as well. I am tempted, but some of the reviews suggest they won't last... https://whosatthewheel.com/2014/12/27/k ... -any-good/ (possibly referring to the v3 wheels though).

Standard lockring (supplied with the rotors) for Q/R and 12mm through-axles, OS lockrings are only needed for 15 & 20mm through-axles.

[hamishm]

Which rotors should I get? RT99, RT81, RT68? ($60, $38 or $30).

My bike came with 68s. I replaced the front one a few months ago because it was deflecting slightly when it heated up and was causing it to rub on the pad after moderate braking. I replaced it with an 81 and it has been fine.

RT99 will give reduced chance of overheating, thanks to the extended cooling vanes. RT81 and 68 will have similar cooling efficiency, however the shorter spider arms of the 68 may make it more prone to warping. The 99s were initially developed for downhill racing bikes, which have pretty extreme braking demands, then were subsequently adopted for road thanks to the early use of 140mm discs, which don't have the heat dispersion efficiency of bigger rotors. I use the 81s (160mm) on both of my MTBs and have had no problems with overheating.

Don't forget RT99 is centre lock only.

[Duck!]

Fairly sure we've convinced him to get Centrelock wheels.

Yup. Just ordered the Kinesis Crosslight wheels and the RT81 160mm rotors. Thanks for the tips everyone!

In the future I might be tempted by some hand built wheels, possibly with dynamo on the front, but I'll give the Crosslight factory wheels a go for now. Now I just need to find a good deal on the groupset (as discussed in my other thread). And wait for the frame...

[hamishm]

By the way, have I got any chance of setting up the hydraulic brakes myself or should I take this to a professional? Given that it's kind of life or death

Seems the answer is....Just don't

I've never set up a hydro drop bar configuration. But I'd imagine it would be a pain. Especially if it was internal routing!

My bike has standard QR, but the wheels came with all sorts of adaptors. Even with adaptors for QR installed, I needed the OS lockring for the rear wheel, but not the front. Pity it wasn't included and wish they'd came with instructions, as one end has flats on the axle for installing the adaptors and the other uses an allen key in the axle hollow. Took my a while to work that one out!

I didn't see any reviews when I bought these earlier this year. They are cheap and light. Seem to have been strong enough so far, but I'm not a heavyweight and I'm generally not hard on equipment. Kinesis have a HD (heavy duty) model which has 32 spokes - maybe that's better for some riders.

There is a bit of mucking around, because it's likely the hoses will need to be shortened to suit the frame. If you're not sure probably best left to a pro.

I was more put off by all the talk of funnels, oil, bleeding and the like...

It's not too bad. One you do it once, it's pretty straightforward. But yes, the first few times expect to spill some oil and make sure ou treat it correctly if it is dot fluid.

*Edit: and don;t get it on your rotors.

I have had the rt99 on my bike for 6500km of commuting ( heavy use ) and have gone through a set of pads on the front, had the front disc develope a kink and now the rear disc rattles when it gets used on a downhill.

I have purchased a a 99 and a 81 and will put the 81 on the rear as it is not used as heavily.

Looking forward to better discs. Not going to be happy if I have to replace my discs every 6 months.

OK, so I got the wheels yesterday and now I'm confused. The front is fine. The rear seems to be set up for 142mm QR. According to the questions asked on eg http://www.this link is broken/au/e ... prod143358 , 135mm QR is supported.

I have no idea how to change the axle, or what to. There's a few adapters in the box but they all look like thru axle stuff. Slaw, did you have to change yours and how? There are no instructions on the Kinesis site that I can find. The front ones just pull out with no tool at all.

My second problem is that my lockring tool doesn't fit around the rear hub. I'm guessing this just means new lockring tool eg http://www.this link is broken/au/e ... p-prod1056 ?

[slaw]

You need two allen keys inserted into the axle ends to change the spacers.

And if you didn't get one, as noted above, you will also need the oversize lockring which uses a bottom bracket tool. The normal lockring and tool will not fit even with the spacers for 135 QR fitted.

[hamishm]

You need two allen keys inserted into the axle ends to change the spacers.

I had a quick try and nothing moved - does it need a lot of force to remove them?

I'm not even sure I have the right bit to replace it with, the others all look like through axle stuff.

[hamishm]

So I have this bit which came fitted, for a 142mm axle. Should I have a shorter one for 135mm axle? I have a whole bunch of bits, most are not threaded (so they are for the front hub) and nothing else is for a quick release.

[Duck!]

That looks decidedly like an end for Q/R; 142 doesn't have the step-down.

Hmm. So is there multiple standards for the axle width with Q/R?

I don't have the frame yet that I'll be using these wheels with, and my other bikes are all rim brake road bikes with standard 130mm spacing.

I think what's confusing me is that I measure 142mm from end to end.


So am I worrying about nothing and I have the correct part already fitted?!

[Duck!]

Rear Q/R is only 130mm (non-disc) or 135mm (disc). A few manufacturers played with the middle-ground 132.5mm for road disc in the early days, but it never took off and seems to have gone into oblivion where it belongs. There is no such thing as 142mm Q/R; 142 is for 12mm through-axle.

[hamishm]

Right, thanks for that. A bit of googling shows that I measured it wrong so no doubt it's fine and nothing to worry about. #facepalm

And if I'm not mistaken my 10 speed SRAM equipped mountain bike has the same spacing so I should be able to check it there. (Don't suppose the ten speed MTB cassette will fit the 11 speed road hub though?)

[Duck!]

Shimano & SRAM use the same sprocket spacings, so no compatibility issues. 10-sp. cassette, road or MTB will go on the 11-sp. hub fine, just use the 1.85mm spacer that should have been supplied with the wheel behind the cassette.
