Question, do you like the Hylix seatpost ? Was thinking about buying one for the BMC. Pretty nice bike - with a very nice weight !!

Hey PinaRene, I am on the fence on the Hylix, whilst the listings state it fits this Cervelo, the shape is a fraction bigger all round than the original, this requires sanding to fit, due to the tight fit, the Cervelo wedge seatclamp is also not sitting perfectly, I haven't done much of a long ride on it, but am worried about it, which isn't a good place to be..

Nice aero build! Could you please specs what to bolts are used for brakes calipers?

So a long story on this, the Hylix seatpost originally supplied was not to tolerance, a half mm on a seatpost in a few directions meant that this was never going to fit, so 7 months back and forth with the eBay seller, and providing the actual dimensions of the OEM Cervelo post, I have been sent a 'revised' version, very slightly heavier than the first one (142.8g for a 365mm Length) but when cut down to the required length for me it comes out at 125.6g (Saving 44.6g over my current one)

It does have a great feature where you can swap around the head clamp area to provide either 15mm or Zero offset.
