The front guard worked well with downtube cable routing and also has an easy strap attachment system. The rear is a super light, simple design with an easy to use Quick Release (QR). It adjusts easily to all post sizes, without tools and there’s little to break or go wrong.
If buying the front on its own it’d be a bit more expensive than the competition. The rear is fairly narrow and it trades rigidity for some angular adjustability, needing to be adjusted tightly to keep it in line. It's also a bit shorter than the Defender/Cycraguard.
