True but cajunpedaler likes her current bike & there's few production coupled bikes. Bilenky never mentioned butting length, just from looks I guess the couplers are far enough from tube ends to prevent that problem. BTW was in LBS today & from quick scan of their bikes I didn't see any 559mm/26" models. Thus I'm wondering if Surly etc will eventually switch most/all 559mm/26" frames to 584mm/27.5"/650B? IE, in future there might be less production models amenable to S&S retrofit since any wheel >559/26 will be harder to pack & will probably necessitate deflating tire to pack.
