I have trifox sdy 20 and its a good frame its as light as the epic ht sworks I weighted it with hardware 850g in size L without seatpost clamp,i think it isn't the stiffest frame but it isn't that bad and sometimes you don't notice it until you reach like  1600w and more but it could be the crankset tbh

How accurate is your scale? Trifox claims 1030g on their website: https://www.trifoxbike.com/lightweight-carbon-mtb-hardtail-frame-boost-sdy20

to be honest i dont know but when i bought it the frame was listed a lot less (8\12\2022) and probably is pretty accurate because I weighted it on two scales and there was a difference but wasn't more than 10 grams, they probably changed with a different supplier or is listed more for tollerances, btw the bike for me is good and all my friend that race xc against me(juniores in Italy) are impressed about the weight of the bike (xtr, formula r1r,rotor carbon cranks with pm, carbon wheels are coming today, fox 32 sc......) and I spent like 2600 not more, some components I bought them second hand
if you want i could send you an excel file with all components price and weight, it isn't so accurate but isn't that bad

the price of r1r seem strange but I bought second hand at 50 euros for the set looool, I had magura t8 but they didn't work well but they changed them in warranty
so if someone want new mt8 I sell them at 220 euros

Man, buying anything from SP-Cycle was a huge mistake and their so-called warranty is just a slap in the face and a bad joke. I'd hate to see others make the same mistake - it'll save them a ton of headaches, at least. Trying to communicate with them is like talking to a brick wall. They don't want to deal with you at all. The only thing they'll tell you is that you can fix it with a tap, even after I told them we already tried that and the threads didn't last long before completely stripping out. Turns out there was no material left to recut the threads and we later found out that the threaded insert laminated into the frame was cracked, so it had to be removed and replaced with a new one, then the whole rear end had to be re-laminated with the new insert.
The whole repair ended up costing me the equivalent of $175 USD and I haven't received any compensation from SP-Cycle to this day. They're playing dead, even though they sent me a frame with a damaged thread straight from the factory and don't even get me started on the fact that the frame is starting to crack under the seat post clamp. I haven't put that many miles on the bike yet. It's been nothing but trouble so far, but I'm hoping I can finally get some decent rides in next season. On the bright side, the bike is really light and flies like a rocket.

Sorry for not posting an update sooner, I've just had a lot of other stuff on my plate and totally forgot about this forum. But I hope my experience can help others avoid making the same mistake I did.
