Well... the SpaCycles UC Double is based on a triple chainline, and their website says you should be using a 119mm BB spindle. That's all fine, but it's not a typical use case.
I'm just pointing out to the community that for the majority, who are using a double crank intended for a double chainline, that Riv's included BB runs a wide of that chainline. And that BB doesn't even match Riv's Silver-branded double let alone other typical double specs on the market. That BB is only chosen to mate well with their "skeleton key" front derailleur, which also doesn't seem optimized for typical double cranks (nor theirs). Riv admits on their website that they're spec'ing as many Microshift items as possible to gain favor with that vendor (to further encourage their collab on a Silver-branded Microshift drivetrain). The BB spec is a loopy business decision where the average user is getting a BB that won't give optimum alignment, and the user can't request an alternative BB (i.e. swap at no cost). I'm less concerned from a cost perspective (since the BBs they sell are affordable), but it affects a person's build parts list and timeline. It's a setup for surprising a lot of people with a mismatch. -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
