Quick update on the AliExpress stuff purchased.
The POC glasses are really good. Glad I got copies as I have dropped them 4 times already.
I have fitted the (only) polarized lens provided and it is actually polarized and works very well. Very comfortable to wear and sit quite high so cover your brows - ideal when you are in aero mode with your head down.
Overall, can't fault for the money (about £14 posted). I might have issues with durability later on but at the moment 10/10

Overized RD Cage - Fouriers double 15t pulleys oversize RD cage for Ultegra 6800 with ceramic bearings. First impression is that it feels lighter than the original bearings and the ceramic bearings don't actually spin better than the original ones when you flick them.
Fitting is not as straightforward as the instructions lead to believe - you have t dismantle both cages to fit.
Once my original RD cage was removed, I noticed that there are actually two spring settings for the Ultegra 6800 RD so if you felt that your cage didn't provide enough chain tension then you could actually crank it up one notch - which is effectively what the oversize cage offers (4 spring settings). If I have known that, I would have cranked up my RD cage tension before spening £74 on the Fourier one.
Regardless, the cage looks good once fitted and I set it up on spring tension 3 (out 4). The gear change feel much more accurate / precise but that is due to the increased chain tension. Also less chain slap. I don't know if I 'saved' any watts but remember that you will need either a new chain or an extra link. (my chain was a tad long and now it is a tad short).
Voila!

VCLS Carbon Seatpost - I needed a long-ish 27.2mm inline seatpost that looked good and was matt UD so I read through this thread and was advised to buy the Canyon VCLS copy. It is made of two separate wedges which slide against each other, allowing you to adjust your saddle angle.
I initially though it was a bit of a faff as you have to completely remove the post in order to change your saddle angle but it is actually quite precise.
The carbon scuffs quite easily so I would advise caution if you wanted to have this on a show bike as once you have inserted it a couple of times, it will be marked (especially if you use carbon paste). I torqued it up properly and the post did not split & there was no crush marks so that's good.
The seatpost has a weight limit of 100kg (which I reach when I carry a bag) and has a certain amount of horizontal flex (which can be seen by other riders when you are bouncing on the back of the saddle - the two wedges slightly flex apart). It is a bit surprising at first but then it is quite comfortable when you get used to it.
I have not ridden an original Canyon VCLS post so can't compare but all in, I think it looks great and it is worth the £30 ish posted.
