OXFORD SCREAMER 7 DISC LOCK

The Screamer 7 is an attack-activated disc lock alarm with a 100dB alarm, motion and shock sensors, a 7mm diameter locking pin that fits most disc brakes, and is tough and durable, and able to scare off any casual bike thieves.

Available in two colours, (subtle) black and (don’t forget I’m here, numpty) yellow, it costs just £44.99 from anywhere that stocks the Oxford Products range or ww.oxfordproducts.com
