  1. Peter Barnes

    The frame is exactly like the ad, very beautiful, and super light, am super satisfied with the acquisition of this frame. Delivery was super fast, surprised me!!!

  2. Valerie Farmer

    In plain sight, wonderful. Without riding it, the first impression, mind-blowing. 913g , in size L. When I mount it, I’ll comment more exactly

  3. Quintin Graham

    Fast delivery to Thailand within 10 days. Great communication.

  4. Darnell Melton

    Frame received by transport very very well packaged, just a hole in the box but no impact on the frame, it was very well packaged I took 10 minutes to remove all the protections! the frame is very well finished and the weight is as described (915 grams in size L) rear axle is 44 grams and headset seems good quality

  5. Mohammad Simmons

    Received as described thanks, fast shipping A+++

  6. poonlaiman (verified owner)

    The frame is very well made. Didn’t spot any issues. The ports for cabling in the headtube are a bit rough on the inside, so it’s possible to cut/damage your brake hose or shifter housing.

    Been riding the bike 3-4 months now with reckless abandon and so far so good. Very stiff frame. Very fast.

    Immediate Shipping, no complications at all; Product as described in the technical section.
    Very transparent, clear and friedly communication through the hole process! Just started to build frame with parts, but looking forward to see how that works!
    Also very good experience with the purchase. The information from the seller ( Dolores ) has been perfect all the time and very nice.
