Ultra lightweight 29er XC hardtail frame options?
« on: June 16, 2026, 06:43:32 AM »
Hi,

I'm building a lightweight XC 29er hardtail and the target is a ready to ride bike with 7,5kg (with Assioma PM pedals, Dubnital 2.4 tires, botle cages, etc).

I already have all the components for this build, except for the frame. I'm currently considering the upcoming SPcycle M038, which is supposed to be available to order in early July at 550~580 usd, with a really low claimed weight of 830g +/-20g (Size M,unpainted). So, given the spec, highest weight would be 850g for an M size (my size), obviously unpainted, as I want it.

I can't find any other frame at this weight and price (both uncertain yet), but if anyone knows other options with a similar or even lower weight, please share!  8)

Thanks.

Thanks for sharing.

I've seen that frame at many sellers, it's the Specialized Epic HT clone, but the weight for the L size samples I've seen were always above 1kg. That is a great weight for an M size, though, and the price is great.

It's an "old" geo frame (short reach, steep HA), so I'll need an L size, instead of the M size I can use in more modern geo frames....
