One piece main wiring loom complete and installed, weighing 15 grammes, its stripped down ribbon cable so current rating etc is OK and its small form so easy to run alongside the rear brake housing up to the bars, with heat-shrink or tape wrapped over, was even fairly easy to thread through the frame.

Also completed the sprint shifter hack to use the brain of a climbing shifter, need to figure out where to hide it on the bars when installed.

Crank installe OK and spins nice and freely using Rotor Bearings.

Close to final saddle height means theres room to trim the seatpost.

I do like those handlebars. Good weight and nice design.

Totally! Where did you order these? Alibaba? Ebay?

Got them off ebay, from Costelo Sports, they also have a website,
I had posted some more details / info on this forum thread about them,

viewtopic.php?f=3&t=144200&start=30

The bars and the moulded spacers are pretty good and interlock, the bottom one with the bolt was distorted on my set and needed some manipulation to get it to sit properly in the stack.

Be aware they are for 1 1/4" steerer and the white plastic spacer shims they ship with are junk and too thin, i don't think you would ever get enough grip on the steerer for them to be safe, hence my custom spacer shim arrangement.
Ritchey, Synatce & Giant do similar spacers for their 1 1/4" stems so they can be bought.

Think i've figured out my Di2 setup, just waiting for a second climbing shifter to turn up and gut, ( its currently lost in the couriers shipping system).
Plan is to use a standard brake lever shifter electronics in the LH shifter,
The brain from a climbing shifter is the same mouldings and bolt spacing as the electronic switch unit from a standard RH brake lever shifter. Since both can be programmed, i plan to replace the RH shifters standard electronics with those from the gutted climbing shifter.
Then stick the sprint shifter electronics module where the RH electronics module used to sit in the brake lever body.
Splice in my Sprint shifter electronics to the RH shifters cable, so that both terminate with one plug and cable that will run to the 3 port Junction 'A', and also run a cable from the LH shifter to the Junction 'A', and that should be job done.

They should all still be programmable, and keeping the LH standard module should allow me to retain the on the fly trim of the mech.
It might even shed a couple of grammes as a bonus.

I already run my shifters similar to SRAM, RH upshift, LH down shift, small paddle for front shifts, large paddle for rear shifts, so reprogram the button function anyway.

Thanks for the info and updates on this one! Due to all the craftsmanship, work and thoughts you put into this it's really interesting! I have ordered a Chinese frame myself (while I am a bit scared of these handlebars tbh) and really cant wait for more updates on this one!

Well, the climbing shifter turned up and a simple update and configuration with E tube has it working as the main shift unit for the RH lever, just need to swap over the electronics module into the lever assembly and shorten a couple of cables.

So, i have a standard shift lever electronics on the LH, a climbing shifter electronics in the RH lever and a climbing shifter electronics module hacked with some sprint shifter buttons fitted into the RH brake lever body.

Next is sorting out the Sram HydroR brake lines, not sure i can do mush to lighten the brakes other than KCNC light weight pad holders and Ti bolts. Also need to design up a custom carbon fibre Garmin mount.

Kidrob, what frame have you gone for and who's the seller. Handle bars in a simple flex test by me seem plenty stiff enough and the seller 'Costello' has some good reviews so will have to see how the perform long term.

pics will be updated later.

Ordered a FM-008 (FM066_EVO) from Hongfu and just bought an Ultegra Di2 group (internal), thus following this with great interest as you seem to be great with these things and its a great project! Does the battery fit all well into the seatpost btw?

Thanks chefczyk,

Yepp battery fits fine in the 27.2mm seat-post, i didn't bother with a proper plastic insert, just a piece of the frames shipping material and a bit of insulation tape did the job and only weighed a couple of grammes.

The FM-008 frame looks nice, did you just go with the carbon finish or have you spent a couple of days and Emails pondering a colour scheme like i did.

Thanks for the info, thats good to hear! I got the di2 on Ebay for a price I couldn't reject, so this had to be a fast shot while I couldn't assure such details.

I went with the default (matte black) finish and am currently waiting for production and delivery (I made a deposit) as the thing is currently not available with BSA in my size. Ima create a gallery entry as soon as it arrives...

Seeing your frame and its nice coloring I kinda regret not to have chosen painting but yeah ;)

Chainrings and mech's installed,

on the left, the control unit from a climbing shifter bolted onto the brake/shift lever, required a small mod to the lever to fit in, this gives room in the lever body for my sprint shifter control unit.
on the right, the standard shift lever electronics module.

A few quick photos after dialling in the fit and position of the shifters and sprint switches, not the best light or background but will take some more on a more neutral background when the bars are wrapped.
A couple of short rides have been good, the only downside is that a light colour in a matt finish is going to be a B****r to keep clean.ImageIMG_5153 by Paul Townsend, on FlickrImageIMG_5154 by Paul Townsend, on FlickrImageIMG_5157 by Paul Townsend, on FlickrImageIMG_5160 by Paul Townsend, on Flickr
