I purchased this bike lock via Sprocket & Gear at a fantastic price compared to other larger shops and online retailers. It is very well made, good mounting options and three keys along with a 2 year warranty. It arrived well packaged and in good time. I had a technical question regarding the lock and John & his team went to great lengths, speaking to the wholesaler and manufacture to ensure they gave me an accurate answer as soon as possible. Really impressed, many thanks!
