For those interested I bought a pf30a J&l gxp bottom bracket off ebay.
The order was £25/$32 delivered.
Comes with ceramic bearings

Weight is 143g with alloy sleeve. Without sleeve it is 109g. I'm going to look at using a plastic sleeve instead.
The bearings are 6805rs and work gxp using a step down adapter so will work with 24mm hollow tech chainset too

Hi guys!
I'm new in the forum and enjoy all information that you all are sharing here.

My wife just ordered a 47 System Six Ultegra Mech(height of 1.53m) which comes with Vision Wheels.
The upgrade to Knot 64 worth the money or the performance is similar?
What the differences between this two wheelsets, beyond depth rim?

Thanks.

I don't know the specs for either wheelset but 9mm in depth is not going to make much if any difference. One thing I do like about the Vision wheels is that they have exposed nipples. If you plan on going tubeless then just think of the hassle it would be to true the wheels on the Knots. Break the bead, remove the sealant, remove the tape, true the wheel, replace the tape, mount the tire and replace the sealant. I have the HG35's on my bike and will probalby not to tubeless because of this. My bike came with wheels with hidden nipples but I would not ever buy a set of rims with them.

^ run your wheels tubed for a little while to make sure the build is solid. If so, convert to tubeless. I haven't had to touch any of my carbon wheels in years, whether they are internal nipples or not.

whats the difference between the knot and save bar on the supersix? just picked up a systemsix and looking to switch to the intergrated bits,

do both the -6 and -17 stems work with both the handlebars?

prefer the matte of the save bar to the glossy knot thats all

The Knot bar is wider and flatter than the Save bar from the Supersix. Yes, both have the same attatchment points. The Knot stem on the SystemSix is -17 and the one on the SuperSix is -6. There is also a Save stem that is more like a regular stem (no cable routing) but attatches to either of the above bars. I think I've seen a flat black version of the Knot bar but not 100% sure.

Apart from the flatter and wider (front to back) top sections, the SystemSix's bar (KNØT) flares a tad more than the SuperSix's bar (SAVE). W1 is the width center to center at the hoods, W2 at the end of the drops.

Both. The closest one has the KNØT, others the SAVE. I think it's mostly a fit thing, changing for the bar width they wanted and going with what Ascension Vélo, the shop that sets their bikes, had in stock.

No, you need this one in a PF30 - PF30a frame: https://www.sram.com/en/sram/models/bb-dub-pf30-a1

so coming off a 40cm ENVE SES Mk2 with 40cm c2c in the drops and 35cm in the hoods, the 38cm matches nearest?

38cm gives me 39cm e2e in the drops and 36cm in the hoods c2c
40cm gives me 41cm e2e in the drops and 38cm in the hoods c2c

so a touch narrower in the drops and a touch wider on the hoods
