I noticed on your inline brake lever you use some kind of adapter (the red bits) for the cable head?
May I ask how I can find such adapters?

Looks awesome! Any thing you feel it's lacking when compared to a Brompton? What was cost of the build?
Nothing major really. The rear locking part was slightly shorter with mine, and I had to custom make the suspension top cap to compensate for that. And the seatpost sleeve is made of cork (the original one is made of plastic) and has much better grip than original one, but I am not sure how long it will hold. And the total cost was around $3.5K (roughly $2K for frameset and $1.5K for the rest)

They are aluminium barrel adjusters, search for "brake cable adjuster" at ebay and you'll see a bunch.

I have to ask - how does it ride? And yes, this is seriously awesome.
Road bike: Cervelo R3, Campagnolo Chorus/Record mix...
Supercommuter: Jamis Renegade...
Oldie but goodie: De Rosa Professional Slx, Campagnolo C-Record...
And you can call me Macktastik Honey Pete Kicks, thank you.

I managed to get a pair of 685gr carbon clincher wheelset. They are not recommended for long descents (heat builds up faster with small wheels) but should be fine for short leisurely riding.

What does that bring the weight down to now, anymore plans to make it lighter.

I didn't like the matte surface so I have ordered new black / polished ti parts. And I have ordered a number of small parts to shave some grams as well.
Hopefully I should be able to shave ~190 grams to make the whole bike slightly less than 5.60kg. Crossing my fingers...

I have made a new pair of pulleys with perforated guards. They shave 9 grams for free.

Impressive! What are those cranks - old Tune Fast Foot's or an Asian clone?

I put together new parts. The bike is now down to 5.56kg on scale.

I am qute proud to use only affordable parts so far ($30 saddle, $70 crank etc) but things may get difficult from now on. Clavicular SE will save ~120gr. AX Orion SL will save ~30gr. Rebuilding wheelset with extralite hub may save ~50gr. But they are quite some tasks and will cost $$$.

I have seen some lighter ti parts (<400gr rear triangle, <400gr handlepost etc) online so it may make more sense to look for those parts first.

You mean the message from official website? I don't think so, cordz can be bought from the usual WW shops. I recently purchased a set at r2.

By the way, did you consider other crank options for 1x or Clavicula SE still remains the lightest? I think this might be my next upgade :lol:

Thanks for the info. It seems they are all gone in most shops... I'll look harder around.
And I think the Clavicular SE is still the lightest option out there, even with recent weight increase. eeWings look awesome but it is heavier than cheap chinese combo (!)
