110mm bmx hub mod to fit 135mm frame. drop a comment under here if you need any info. You will need to remove the thin axle nut that would sit up against the drive side dropout completely. Then you need to fit a nut on either side of the hub (the silver nuts on the inside of the dropouts shown in pic). once you have done this, you will need to change the ofset of your rim. to change the ofset, you will need to tighten the driveside spokes and losen the non-drive side spokes accordingly.
