I have not heard of this brand before. Chain reaction cycles' own brand?? Posted this because the kit (with 105 kit) on the bike looks decent and couple of good reviews. Looks like a lightweight bike too. All the sizes are available at the moment. Extra 10% off if you have British cycling membership. I will leave it to the cycling experts in the forum to judge.

Vitus Bikes Zenium SL Disc Road Bike 2016

All new for 2016 we have revised our highly popular Zenium SL model to feature the pinnacle of braking performance on road bikes by the addition of disc brakes. Featuring low weight and supreme durability at a fraction of the cost of carbon counterparts; what’s not to like!

The Zenium SL features a custom designed superlight alloy disc brake specific frame which has an ultra durable and weight saving anodized finish, a full carbon disc brake specific fork with 15mm through axle; Shimano 105 11 speed gearing; TRP Spyre disc brakes; Fulcrum Racing 5 Disc Brake wheelset and Vitus finishing kit to complete the package.

Super Light 6066-T6 Triple Butted Alloy Frame With T700 HM-UD Carbon Fork

The 2016 Zenium SL frame features a super light 6066-T6 triple butted alloy tubeset with smooth welds; we have omitted a brace on the seatstays to help tune out road vibrations and have flared the seat tube at the bottom bracket junction to increase lateral stiffness for optimised power transfer and vertical compliance to combine the best of both worlds; up front a tapered headtube and oversized hydroformed tubing culminate in razor sharp handling.

Our semi-sloping endurance geometry offers a balanced ride resulting in reduced rider fatigue and confidence inspiring handling. The T700 HM-UD disc brake specific full carbon fork features a tapered carbon steerer for increased steering precision with reduced road buzz from rough road surfaces. A 15mm through axle provides enhanced braking performance and improved handling to counteract the brake forces which are transmitted through one side of the fork.

With tyre clearance up to 28mm wide tyres the new Zenium SL offers great all round, all road capabilities.
