[scottydonald]

looking great; i really cant wait to get the DA12 stuff on my bike; i have been toying with the idea of replacing my frame to an S5/SL7/SLR01 but the frame is just so good that i think i will wait another year and see what the next iterations of the S5 and SL8 are like.

With your Power Meter i would just got the peddle route to get your bike weight down!

Looks great! One thing - your build list says 109 links. Should be 106?

Marginal Gains..

@Lucendi made some cool 3D printed things for my bike. Top skills.

Replace the aluminium stem cover (serves no mechanical purpose, everything is within the stem) with a 3D One

The round thing in the pic below


Saving a massive 6.2g - (Al 8.5g - 3D 2.3g)

------------------
Replace the Carbon Bar End plugs with 3D printed ones



Saving a massive 1.9g - (Ca 4.7g - 3D 2.8g)

You are very welcome! The top cap and bar end plugs look great on your bike!

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

Hi! I have the same bike model and was hoping if I can buy these bolts? Thanks

[Bien]

So...

Some updates, as part of my yearly strip and rebuild..

Cranks:
Sanded/Polished Quarq Cranks (The logo's have always annoyed me!)



Savings 4.3g


Stem:
After conversations with Cervelo, who advised it was OK to cut down (as you do when you buy a smaller than 54cm frame), I removed approx. 25mm of the Quill.





The stem weight went from 234.6 to 218.2

Changed out the M5 x 100 Compression bolt and the M6 x 45 stem bolt for TI versions (after much searching for suitable replacements)








Compression Bolt: 14.6 > 7.7
Stem Bolt:11 > 5.9

Quill Removal: 16.4g
Bolt Changes: 12g

Total Savings 28.4g


Bars:
Removed approx. 20mm from both ends (have never grabbed that part of the bar)



272 > 263.2

Savings 8.8g

Cassette:
Dura-Ace CS-9100 11:30 > BDOP 1 Piece Steel 11-28



206 > 179.5 (185.7 with Lockring)

Total Savings 26.5g

Still to come, Wheels and a few other bits, also doing a bit of friction reduction at the moment..

Sorry,

Do you have the DIN for the Bolts? Thanks, I am having problems looking for them here in Germany

[stevec1975]

Hi the bolts are specified in the S3 Manual:
The stem expander one is m6 x 45 (1mm pitch)
The headset compression one is M5 x 100 (0.8mm pitch) - I sold my spare one of these + they are fairly hard to find..

[Bien]

Hi! Thank you for the reply.

Just one question, do I still need the m5x100 if I cut the Stem 25mm? Thanks again

[stevec1975]

Yes, the fork has the wedge component, cutting the stem removes the part that the fork doesn’t wedge into, therefore it makes no difference to the bolt lengths

[Bien]

Hi!

Im breaking my head looking for the m5x100 titanium. Any leads?

Thnx

[stevec1975]

So updated a few parts..

Changed out the GXP Crank Arms to DUB (and sanded/polished to remove the Red logo's)



and the corresponding change to BB as well.

Total Saving - 119.4g

Added a CS OSPW:



Total Gain 27.9g

Plus changes to Stem Cap, Bar Plugs, TI Bolts and adding RS-801-S Sprint Shifters

And now, finally, it is UCI Illegal!



Nice.

[scottydonald]

wow. looks aesome.

What is the total weight of the crankset?

[stevec1975]

636.2g for the DUB Crank (vs 727.4g for the GXP version) + 28.2 saved on the BB

[drumjdds]
