    Lightweight Dahon Mu Singlespeed

    I singlespeeded my Dahon Mu XL frame and modified it with some light parts:

    * Wheels: Kinetix Pro
    * Tires: Kojak
    * Tube: Schwalbe XX Light
    * Cranks: SRAM RED carbon
    * Innenlager: GXP
    * Pedals: Wellgo MG1 TI
    * Seatpost: SDG I-Beam
    * Seat: SDG FX
    * Chainring: TA Alize, 49t
    * Chain: KMC X10-SL
    * Sprocket: Reverse single speed kit, 13T (Transmission: 49T front to 13T rear)
    * Brakes: Avid Single Digit SL/Speed Dial SL, 482g (w/o cables)
    * Cables: Shimano XTR
    * Bar: RaceFace Carbon, 98g
    * End Caps: 6g

    Didn't weight it yet, should be around 8kg.

    Yea , having single speed does save on weight of more drive train parts.

    What's a "Sprocket: Reverse single speed kit"? Sounds like something you'd use for a left hand drive.

    You've done a good job on that - I particularly appreciate the understated look of the bike. Probably not a bad idea in Berlin!

    "Reverse" - just the name of that brand. Here's a pic:

    @Elvis, it follows the "rat bike" concept, yes.

    Still looking for some upgrades. I want a left folding stem, a little shorter, and without telescoping stem nor quick release.
    Here's a pic:

    Found on this page in China.
    Anybody heard of these "FNHON" handleposts?

    I dig the wheelset.
    I wanted to get them for my Silvertip but sold the bike already.

    My FN Hon (2 screw top on left of picture is stiffer) and Dahon (quick release top) both fold down to the left of the frame.
    Pics show the Tern post folding left, these are probably the stiffest but I have never seen them sold anywhere.

    I think any of the 3 on the right of your picture would be a vast improvement on rigidity over the crappy 2 piece handlepost.

    * Yes, Lock Jaw Minibike is nice, but 3kg fpr the frame alone is just to heavy, and does not fold small.

    * Tern handleposts would be interesting, but regularly "N-fold" to the right (forward), and require longer fork. So no way to use them on a Dahon.

    * yeah, 2 screw top FNHON would be the one to go for. Did not understand how to order those via taobao agent though. Could you point me to it?
