Hi All,

Just wondering if anyone has built this frame recently?

Looking at purchasing one.

Hi,
I'm planning a build with this frame. I'm aiming for a sram transmission groupset but i get a bit confused.
Light carbon specifies the frame to have a 52 mm chainline and UDH. Transmission (that can be attached to an UDH frame) seems to be having a 55 mm chainline.
Is it a bad idea to use sram transmission with a 55 mm chainline on this frame?

The reason for transmission is that I also looking for rockshox flight attendant suspension which is a perfect match with the transmission.

They're telling me this is available in 120mm, has anyone got one with 120mm frame travel? Thanks!

I’ve just completed the build.

Haven’t had a chance to ride the trails yet, and will likely shorten the stem a couple spacers.

No real issues apart from the spacing with the rear shock mounts - had to clear out a fair bit of paint here to get the spacers to fit.

The colour was a bit off from what I wanted, however it still looks great.

Looks great!!  Is this the 90mm rear travel version?  What is the weight of the bike?  Did you weigh the bare frame by chance?

So they make this frame with a 120mm rear travel?  Is it a different shock or linkage?

I am also very interested if available in 120mm, you are sure they offer this frame with longer travel?:)

If it had 120mm of rear travel it would be awesome, right?

120mm up front, 90mm in the rear.

12.0kg as it stands. I can probably get it down to 11.5kg by swapping out the Reckon Races for a lighter XC tyres. Puts it pretty close to a Supercaliber.

Didn't weigh it as a bare frame sorry.

Lightcarbon offers 2 different fork length versions? That be 2 molds for every frame size, as the geometry needs to have different seat tube and head tube angles.
By what I've found fork length for this frame is 520mm that's a fork with 110mm suspension.
A 120mm fork has a length of 530mm, a 100mm fork a length of 506mm, at least RockShox forks, but this should be universal.
