enter image description hereI tried everything, saw many catalogues and also tried with the serial numbers but still nothing.

this is the serial code I think. From what I can read I see it's BNRB300131 and the other code P21547 this is the serial code I think. From what I can read I see it's BNRB300131 and the other code is P21547

    Have you checked vintagecannondale.com/catalog for various years? Looks like it could be a F-series bike, the cable routing on the top tube can be rather seen on older models (late 90s to early 2000s) but I haven't seen any exact match...

    @Giovacar Why did you remove all the photos?

    @Criggie because the bike looks now a bit different but not enough to pass for a different one if there's a reference around: bicycles.stackexchange.com/questions/94040/…

    Without the photos the question (and hence the answer) is meaningless. Please revert that last edit

1 Answer 1


I don't believe it is a Cannondale.
Here's why:

  1. It has a downtube decal on both the down tube and the top tube. Companies are very picky about branding and this is not how Cannondale labels it's bikes. Someone may have removed the original stickers and purchased Cannondale stickers for some creative branding. Search for "gold Cannondale frame stickers" to see examples.
  2. It has a WAG Bike suspension fork
  3. It's difficult to see but it looks like the crank is all steel. Steel riveted chain rings for sure and it looks like steel crank arms. Cranks like this are typical of department store bikes.
  4. Cannondale did make some frames with square tubing chain stays but I can't find anything with as much square tubing as this frame.

One way to prove it's not a Cannondale is to show that it's really something else.
I have been searching for any mountain bike that matches and am having trouble finding a frame with this much square tubing. I'll keep searching and maybe someone else can help confirm or disprove my theory.

    the WAG bike suspension fork was added by me later, but the original one was with "cannondale" sticker too (actually it looks like it's printed on it). I actually modified almost everything apart from that frame. It's all new, I also changed the handles today. By the way, I think you're right, it could be a reproduction based on some model from Cannondale, but it's not cannondale. everything is aluminium though. I'm going crazy trying to understand what this frame is, because I'm also seeing other brands too. Those serial codes don't help at all.

  • I changed the suspension, because the old one wasn't working the way it was supposed to anymore and took another one which is actually better, it's aluminium too and it allows you to enable/disable suspension and set it lighter or heavier
