Hashtagg Screw-on Alloy Sprocket

 Description and materials
- New screw-on sprocket from innovative French brand Hashtagg for the 2015 season.
- This is an ultra-light sprocket, CNC-machined from a single piece of 7075-T6 aluminium.
- Thanks to its aluminium construction, it’s a lot lighter than steel sprockets, whilst still being strong enough.
- Furthermore, it features a 11mm wide base, which ensures a good number of threads are in contact with the hub/crank, making it a lot harder to strip the threads.
- Standard 1,37" x 24 tpi thread, suitable for most rear hubs and cranks (get in touch if you have any doubts!).
- Two versions available: with 12 teeth (12t, usually the choice for 20” bikes) or with 15 teeth (15t, usually the choice for 26” bikes).
- Teeth are located 4mm (15t) and 7mm (12t) away from the side to allow enough clearance.
- Both versions feature drills around the base (one per tooth, with bigger drills on the 15t version), to avoid unnecessary weight but also add a nice touch.
- Can be used with most 1/8” and 3/32” chains.
- Anodized black finish, with white laser etched #Hashtagg logo on both versions.
