Yeah I was surprised by the weight related answer too.
UD is a quite boring finish indeed.

For me 3k is the one that look the most "carbon" of all.
But only UD was available for the X-256 frame.

As a consolation the other carbon parts will be 3k.
And the Lefty tube is 12k.

Here is an old post on weight weenies about alternate grips for a gripshift.
http://weightweenies.starbike.com/forum/viewtopic.php?f=1&t=111890

It looks we can cut the grips to the size we want after all.

Just a doubt, when checking again the picture.
Is it just while waiting, or do you invert the brake levers right-to-front, and left-to-rear?

Another question to everyone, does the internal routing can be hacked, to allow to cross the hose/cables in front of the bar?
Entering the rear derailleur cable from the left of the frame.
And the rear brake entering from the right of the frame.

I will start my build with a gripshift too in a couple of weeks.
Could you post a picture on how this looks assembled?
It will alleviate my impatience

Peter, the light-bicycle.com web site is public, they do not hide anything.

I related what happened, as it may help some people know there is a lefty compatible wheel builder.
Don't worry, you are by far the darling of this forum. It just didn't work between us.

The Honsen website is also terribly slow.  Looks like just another me too trading company that also posts false information if they say they are using T1000 carbon when, according to Peter, is unlikely since no Chinese manufacturers have access to T1000 carbon.

May be we can give Honsen the benefit of the doubt.
Until we see what kind of frame I get.
So far, everything looks to go well.
Ok, the moment of truth will come after my first big jump, ending on a sharp corner.

T1000 and T800 is just the stiffness of the carbon fiber.
The fiber/resin fraction, and how the sheets are layered in the various parts of the frames are more important.

My choice may look odd today. But end of May, I was turned off by Peter when he told me there was nobody building wheels with Lefty's hubs in... China.
This didn't give me a trusty image as I just saw a couple of hours later that light-bicycle was building them.

Then from the posts on mtbr at that time, the leading time for the IP-256 was quite worrying.
They did not even reply to the people who ordered them anymore.
So I tried Honsen as Leo was responsive and very competent too.

One big step today.
The wheels were sent last Friday from China and arrived this afternoon in Belgium.

29er - 30mm hookless, in 3k matt.

The front with a Project321 Lefty hub.
The rear with a Hope Pro2 Evo to put the XX1 on it.
The set weights 1530g.

I'm very happy of light-bicycle.com

First as they were the only one to provide this combo without asking me to provide the hubs.
Then Nancy was very patient, and answered all my, and sometimes stupid, questions.
And Kartrin did all the administration and shipment details.
And finally the set looks perfect.

The only missing part now is the frame.
But Leo ( from Honsen Bikes ) told me it should be shipped very soon, as planned.

The bad news, is I didn't care about dates, and have some vacations planned for early July.
So I'll have to leave all this sleeping for a couple of weeks

That is a sad lesson. I'll check my car the next time I put the bike on.
Thank you for sharing this.
