Most people don't care about resale value because they don't sell their bikes or frames anymore; instead, they ride them until they end up cut into pieces in the trash or sit in the basement or garage for years. That said, I would never buy a frame from Winspace for the price of an SLC5. However, I would also never buy an S-Works or something similar from a Western company at those prices. And i would absolutely never buy a used frame, no matter how expensive it was once.
I'd disagree, unless you are like Patty Lino who is just rolling though China frames for content on YouTube, I think resale does matter since these China brands move through product cycles extremely fast which is a pro and a con. Chinese D2C are able to easily re-tune or recreate a frame on the fly year to year, heck even every 6 months in the case of Winspace, but with the downside that there is a fear that you buy a Chinese frame and in 6 months it's already dated in terms of specs, and since these frames really rely on "value" and spec hunting, a lot of people who buys these bikes are not doing so to buy a "lifetime" bike or a bike they probably will use for the next 5+ years. In contrast if you buy a Specialized or whatever, you are paying a premium but you have the satisfaction they run on a three year product cycle, thus when the SL9 comes out this year, you can rest easy it's not going to be revised 6 months later.
I personally have fallen for this Chinese spec chasing trap and combined with the major increase of D2C Chinese bike frame costs now being $2K-$3K, I personally don't see the reason to go Chinese (frames) unless they are offering a spec and/or value that a Western brand simply isn't offering yet, ie this Tavelo Arden since there is now maybe one aero bike that support a true 35mm tire, ie the Canyon Endurace CFR which isn't even available yet in the US and two it's only a complete bike in Shimano DA at $10K+. So I can see this Tavelo Arden actually ticking a lot of boxes, however the big names in Trek, Specialized, Giant, and so on all have to see these trends coming right? Right? You would expect they have something in the pipeline. The fact that a good deal of Western race bikes have been released already in early 2026 and tire clearance hasn't really expanded at all, would indicate these Western brands are still at least a generation behind the ultra wide tire clearance trend
