Re: Cranbrook Pre-Build Mockup and Advice
Hi. These engine kits are relatively easy to mount up...especially on a Cranboob. The rear coaster brake will require some mods, like bending the arm slightly and you may also possibly have to grind down the dust cap a bit- see "Dust cap mods" in the Classic posts forum here.
BGF has mixed reviews as to their service and "warranty" but other than that, they are the same as just about any in-frame kit.
Someone else will have to help with the seatpost question, I've never used one like that.
Welocme to the forum
