    Cervelo S3 Disc build 61cm

    Wanting an R9150 Durace Di2 hydro build and needing 180mm cranks, I elected to order just the frameset. I'm having to scour ebay for international sellers that have the various group components. It should be a good four weeks before I have all the bits here to build it. I'll post it here when's its done.

    Stuff I have ordered for it:
    R9150 Dura Ace Di2 hydro
    -11-30 D/A cassette
    -Di2 Junction A inside bar EW-RS910
    -160mm SM-RT900 (R9150) front
    -140mm SM-RT900 rear
    -G04Ti pads
    Lightning 180mm cranks
    SRM 110bcd power meter
    SRAM Red 11s 52/36 chainrings
    3T Ergonova Team 42cm
    PD-9000 D/A pedals - used
    Light bicycle 46mm tubeless DT240 straight pull CX Ray 24H
    25mm Schwalbe One tubeless
    Specialized Romin Evo carbon 155mm
    Garmin mount for Edge 520 - used

    I run lightbicycle 46's on my Gravel bike and Shwalbe One 25 tubeless on my TT bike. Good experiences with both so that's my new road setup. All my bikes are tubeless finally (yay)

    Weights
    1383g Frame, bare
    15g battery tray, inside DT
    18g Seat binder wedge
    1416g total

    420g Fork, uncut
    1836g Frame & fork

    62g Front axle 12mm
    72g Rear axle 12x142mm
    80g Headset, 1.125 upper, 1.375 ACB lower
    225g post, uncut

    Tire clearance for 25s with wide wheels no problem. Pic below (demo 58cm bike) is OEM Conti 23mm on Enve SES 3.4 24mm external width. I don't think 28's will fit unless you shoehorn them onto really narrow rims which defeats the purpose of 28's anyway.

    oops, 61cm. Updated title.

    Lightning carbon cranks are on the way to SRM. SRM was very helpful and suggested I let them install and calibrate. You bet!

    DA 9170 Di2 hydro shifters and calipers won't be available until almost July so I bought some takeoff ST-RS785 (Ultegra-ish) shifters and BR-S805 (105-ish) flat mount calipers to build it in the meantime.

    Lightning cranks - SRM

    Cranks arrived from SRM after being calibrated. Wow they are light.
    The SRM spider is for the Specialized FACT cranks, which is the same spline as the Lightning. Wireless PowerMeter - Specialized Compact

    344g 180mm cranks only, no bearings
    120g SRM spider
    77g bearings, cups

    Wheels should be here in a few days. Woot

    Swapped the 62g Cervelo front QR for a 32g Rockshox Maxle # 00.4318.005.016
    So clean. 72g rear QR will be replaced with a 28g Extralite Blacklok 12.3 bolt on.
