« on: September 02, 2026, 07:30:59 PM »Do you mind sharing the reason why the QuickPro cracked? XMCS downtube does not flex as much as the QuickPro because it has an internal ridge to make it torsionally stiffer and more robust. Explained here by Hambini https://www.youtube.com/shorts/cZ6GjRGhaFg
I would have happily purchased the XMCS instead of the ER:One, but in terms of aesthetics there's something in the VRT that I don't like. It is not something specific, it is more something like the overall proportions of tube shapes, ratios and angles (but it is a highly subjective opinion)
I’m not sure what the reason for the crack was - it certainly wasn’t anything I had done that I shouldn’t reasonably be able to do on a carbon bike. It wasn’t crashed, and was fairly new. It cracked on the underside of the bottom bracket shell, running up to one of the seat stays. I’ve seen at least 2 others online that have cracked in that same place, and that might lead me to suspect there is something in the design, layup or general structure of the frame that is in issue. Of course, they could also just have been a bad batch.
I wouldn’t worry too much, especially if you bought it new. I got mine from Panda Podium. They are a real decent bunch there and did everything they could to ensure Quick sent out a new one.
