Already got them installed, might do 140mm rear (which loses the adaptor as well for a c.28g saving)

I can't think of anything else besides perhaps shortening the seatpost to min insertion depth based on your final set up height. You have pretty much everything I would do and more (I normally can not tolerate 3rd party cassettes and will always try to run a Dura-ace no matter what).

The old school trick was to run TA-specialities chain rings to save maybe 50 to 100g, or look into Extralite chainrings.

The frame @1126g and fork @422g is hurting the build to get to sub 6.8kg. An older Cervelo S3 / Cervelo SLC-SL from 12+ years ago weighed around 875g for the frame and the 3T funda fork weighed 370g ish... You are also stuck with Cervelo proprietary stem.

perhaps the suggestion I made earlier of trying out the Ritchey (https://us.ritcheylogic.com/us_en/super ... -handlebar). This will save you 63g ish... But at a pretty expensive price, the MSRP is $330 USD.

Looking at the new Prime Carbon bar (https://www.wiggle.co.uk/prime-primaver ... -handlebar), should be <220g in 38cm form, it's designed for internal routing, just not sure if I can fit 2 x Hydro and 2 x Mechanical gear outers through the hole, anyone got these bars that can measure the size of the hole?

In other news, swapped out the heavy Barfly Wahoo mount for a MagCad 3D Printed aero one.

32.9g > 13.3g

Savings 19.6g

Every little helps, bike now comes in at 7.18 kg.

Nice work. Do you have a link for the M5 x 100 Compression bolt?

I got the last 2 the guy had (had to buy it in a pair, so I do have 1 spare). If you are in the US you will be able to find it somewhere, but minimum order quantity is usually quite high.

I can sell my spare with the corresponding Ti stem clamp bolt M6x45mm if you are interested? PM me
