Modular Saddle Rail Mount

thingiverse

Saddle Rail mount for common 7mm standard rails, should work up to 9mm MTB and BMX rails as well. You need M3 hex socket head bolt and M3 nut (nyloc possible, probably not necessary though) to assemble the brackets on the rails and 16mm M5 bolt along with M5 nyloc nut for attaching the modules, washers may be of use. Included is an "aero-special" module for rear carrier rack mounting bicycle rear lights with 50mm bolt distance and an extra link for between the bracket and the light mounting unit if needed. Recommendable rear light for this saddle mount, B+M Toplight Small, dynamo or e-bike version (depending on your bicycle configuration), nice and small especially for sporty bikes without rear carrier and if you want to position the light higher (than seat stays, for example) on the bike for better visibility, more useful particularly in heavy traffic. Other small rear lights or rear carrier lights of any size for that matter with 50mm bolt distance are applicable.
