Purchased a FS frame in December 2025. The bottom bracket threads de-bonded from the frame after 2 months of gentle riding. By June 2025 a warranty claim was accepted but as of now ( February 2026 ) I have not received a replacement. Ty communicates poorly and rarely responds to ( civil ) emails. Instead of riding a bicycle I have excuses about " manufacturing backlogs " and " illnesses " and less money in my account. Update : The day after I wrote this review Ty contacted me to sort out my warranty issue and 3 weeks later I got a refund.The day I received the refund Ty contacted me to withdraw my review but I decided to amend it. Response to the Reply: I would like to reply to Ty's reply to my review. I have been nothing but accurate and courteous in my review but feel that your response is distorting the timeline and the speed or lack of your replies to my emails. After accepting the warranty in June it took 2 months of silence from your end before telling me there was a holdup at custom paint for the frame and you were " getting it pushed through paint ". 1 month later you wrote " the warranty is good to ship now ". 2 months after that you were telling me the frame was still held up in painting ( we are now 5 months in ) and offered me a non-painted frame declaring it would ship in 7-10 days.At that stage I agreed to taking a non-painted frame. 2 months AFTER THAT you wrote that my frame is still held up in paint and offered me a non-painted frame. I hope you can appreciate how frustrating the whole process was. In particular I can count 28 emails coming from me with over half of those not getting a response. As I declared above You did send me a refund and as far as I am concerned we are good.

*Updated 9/15/2023 with dates of correspondence* Buying a set of integrated aero bar and stem from DiyCarbon was a huge mistake. First off the bars I received did not match what the site photos looked like. That was okay because they seemed fine. However, the advertised reach was 77mm and I made the mistake of building this bike up including routing new hydraulic brake lines, without measuring it. After the first ride it didn’t feel right and I found the reach was actually 122mm. That’s an entire hand size too long! I reached out to Ty, the Owner, with photos and his response was that the stem size was correct, but he made no mention of the reach. It seemed like he didn’t actually understand what reach is. I own eight bikes, 4 of those are drop bar bikes and I’ve been riding and racing for over 30 years, I kind of know a little bit about bike sizing and geometry. I responded a second time with photos using a digital caliper and did not hear anything until I started leaving poor reviews and filed a complaint with the BBB. He finally responded and we came to an agreement to remedy the situation, but I certainly would not recommend buying from there. Timeline: August 4th, 4:03pm - I emailed with photos showing the reach was incorrect. August 9th, 11:57pm - I emailed again asking for an update. August 11th, 12:21am - I finally received a response saying the stem length was correct but they did not address the reach issue. August 11th 7:20am - I emailed again stating the reach was incorrect and asking for a resolution. August 13th 6:24pm - I emailed again, this time with photos using a digital caliper showing the incorrect size. August 15th 7:00am - I filed a complaint with the BBB and left this negative review on Trustpilot. August 15th 11:39pm - I received a response offering a resolution. Stated they took them a few days to investigate the issue. The problem here is I never received a response saying they were looking into it. I didn’t get any proper response until I left a bad review.

I ordered on December/23 and finally received all the parts I ordered in April/24.

Paid for express postage and it still took a month for the carbon frame to arrive. I ordered a hardtail and noticed a small crack in the seat tube/top tube which I documented and sent to “Ty” (the CEO), who assured me it was just a fault in the paint work. After 4 hours of labour and lots of money spent on parts I took the new bike for a ride, during the ride I could hear several Pops coming from the rear of the frame. When I got home and had a look the crack had tripled in length there were 4 new cracks around the major one. I have asked for a refund but “Ty” tells l me the cracks are all superficial and should not effect the performance of the bike and offered me a repair kit. Absolute crap. I have a new bike lined up to buy and need my money back before I can afford it but “Ty” is now taking days to reply to emails. I will pursue PayPal for a refund. DON’T BUY THESE BIKES!

May 2, 2022 I inquired about ordering an XCR 29 "Epic" boost frame in the "colorshift green" color and XL size. Ty replies, "Yes that one is available in green color shift! You can put that in the checkout notes and we can do it. Thanks and let me know if you have any questions, Ty". May 5, 2022 I placed the order for the frame for a total of $445. The charge posts to my PNC checking account on 5/13/22. According to the DIY order status page, I should receive my frame between May 20, 2022- June 14, 2022. June 13, 2022 After asking for a shipping update. Ty replies that my frame will ship in 2 days. June 24, 2022 No frame. I ask Ty which shipping courier he is using and replies "It’s EMS and will be USPS on the last leg". Problem, the tracking number Ty provided "T202206155465956" is not a valid. June 25-26, 2022 With still no frame, I ask Ty to cancel the order and provide a refund. His responds telling me the frame has shipped, however the only way for me to "track" the frame is through Ty's website with his tracking number. It is not linked to the actual shipping company's tracking like most online retailers. His tracking # is not a valid EMS #. He is expecting me to take his word that the frame was shipped without providing actual proof. He could not even provide an origin scan. I tell Ty that without proof that the frame shipped, I will contact my credit card company to dispute the charge. Ty's responds with a passive-aggressive "threat": "Disputing the card would definitely delay things including a refund if the item was lost but that is very rare." As of August 24, 2022 Still no frame or shipping updates from Ty.
