So I’ve always heard that stamped bearing holder frames which are for square taper hubs, will typically fit an ISIS hub.
Well, on this premise, I purchased one of the few remaining superwide non disk ISIS hubs from compulsion, and a Nimbus Titan frame. Now that I have everything in hand, it looks like the bearings don’t seat all the way down into the holder.
Rather, the bearing sits on two points within the bearing holder.
Is this what people are talking about when they say that they work together? Seems a bit sketchy…
Either way, even if it ‘‘fits’’ as we say, it doesn’t touch the bottom of the bearing holder. The stamped frames are usualy made for 40mm bearings. I’ve used a few and worked fine as long as you dont overtighten the bearing caps.
