Ultralight hardtails

[edraven]

Please post the lightest hardtail frames you've found, in the same vein as the S-Works Epic HT (790g), the new Ridley Probe RS (760g) or a Mondraker Podium Carbon (775g)

I'm having a hard time finding anything even sub 1000g, let alone sub 800g.

I just came across the Spcycle SP-M038 which claims to be 780g!

Can't find any mention of someone online actually reviewing one or even talking about it though.

Nice find, and good price!

The M038 with an eccentric BB would make for a really light single speed.

Agreed.  Very tempting.

Great looking option but be aware that the rear brake mount is the same as the M016 frame so some calipers will not work. For Shimano, SLX and up will be fine but some of the cheaper ones, M6000 in particular, have a bleed port casting that hits the frame.

An M6000 brake on a 800g frame seems like an oxymoron.

I’d look for a set of used Level TLM Ultimates for a budget build.

I purchased one of these frame about 1-1/2 years ago.  Finally built it up about 6 months ago.  Bike total weight can just under 19 lbs, with a Sid Ultimate SL 100mm travel fork.
(Total Weight depends more on what wheels and tires I am running on it.) To date, I really like how I build up this bike.   It climbs well, it is a 'lively' great handling frame.  So far,  I really like the bike!!!

could you share built specs to have a reference?

Did you weigh the frame before you built it up by chance? Wondering how realistic that 780g number is.

If I recall, my large frame was just over 800 grams.

I'll take a picture as soon as I can and post along with description of the main components.

Which paint did you get?

Agreed.  Very tempting.

Here is the BB I ordered of Ali:

I also have a Wheels Mfg arriving next week to compare.
