I would give it 4 1/2 stars, it is a very light weight frame and customer service was great even outstanding, though I had some issues with scratches on the paintjob. BB is 73 not 68 but this is more of an advantage and makes bike stiffer. As you can see the frame and fork look really good together and my bike weighs only 5,9Kg. I would recommend the frame and bike from the point of my experience so far. Now time has to show that the frame will last.

My frame is large size and arrived very well packed and without damage.The initial impression was great. The frame is very well finished and looks fantastic.Inside the frame tubes, the carbon is well made and high quality.Assembling the frame, the head tube bearing fit is very good and bottom bracket is also well made. Rear brake mounts needed dressing with a file on the top faces and also benefitted chasing the threads with a tap - something I’ve had to do on Italian and American frames as well, so nothing unusual there.I noticed an alignment problem with the rear axle on the drive side and found the derailleur hanger thread was misaligned. A quick email (with photos) to Trifox explaining the issue I had a new replacement hanger mailed out straight away. Awesome customer service!Built up with XT brakes and gears, BikeYoke Divine SL dropper post, Reba fork, DT240 hubs and Stans rims, the bike ready to ride is under 10kg with pedals and bottle cages.I’m very happy with the way the bike rides and would recommend Trifox.

All items were well packed and arrived on time. The only difficulty in building the bike was that there was a lot of paint on the bottom bracket and I had a hard time cleaning it properly. The bike is now very well built, rides great, super light, and is a lot of fun.

The frame arrived very well packed, is very neat and very well painted.Mine in size M weighs 881 grams. Now I just have to mount it and try it out.The thread of the bottom bracket is done well, the caps are screwed very well without uncertainties.trifox is a guarantee.

Hi Trifox, I'm torn between 4 or 5 stars. The frame required two rework jobs. The contact surfaces of the brake caliper were factory machined, but one surface was milled to be completely bent. I had to rework both surfaces so that the calipers would align properly. Another issue was the bolting of the chain toggle hanger. The barrel shaft and/or rear chain toggle would not screw in/fit easily. The misalignment was quickly resolved with some filing and sanding. No major issues were considered overall. Anyone with a little manual skill and experience riding bikes should be able to set it up. So far, the new bike has covered about 500 km. the M size frame is very light. I removed everything from the frame and the weight was 833 grams. The bike is made from a Shimano XTR 9100 12 speed kit and some lightweight components and actually weighs 8.6 kg. The bike rides very well and so far I'm happy with it. I hope it stays that way. Best regards Herbert
