Hydraulic disc brakes on a race bike? The Attain SL Disc proves that this doesn't need to be a contradiction. Its braking performance - assured, and with the minimum of effort - is a match for its cornering ability on narrow, tight turns or its climbing prowess on steep mountain passes. As you'd expect from a bike in the Attain Disc series, its ergonomically balanced and comfortable ride position is the perfect setup for any adventure on the road.
CUBE's engineers dug deep into their bag of tricks for this frame. To improve its rigidity, they treated it to X12 quick releases front and rear. Both frame and fork have been specifically developed to work with disc brakes. And for the frame material, they've chose CUBE's formidable Superlite aluminium tubeset, joined with their Smooth Welding process and featuring internal cable routing for clean looks and minimal maintenance. The Flip Flop adaptor means that either 140 mm or 160 mm discs can be used on the front wheel. For winter training, there's even the option of mounting mudguards to keep the spray off.
The Attain SL Disc features a whole range of technical highlights. Shimano's proven 105 groupset new delivers the shifting performance you've come to expect in 2x11 format. The compact chainset with 50-34 chainrings drives a cassette with 11 to 32 teeth, while newly developed Shimano BR-RS505 disc brakes with 160 mm rotors front and rear bring it all to a halt. CUBE opted for the superb Racing77 Disc system wheelset from Fulcrum, and shod it with Continental's grippy Grand Sport Race SL tyres.
- Aluminium Superlite - Extremely high tensile strength heat-treated 7005 aluminium alloy is developed for the highest requirements. It is very stiff, fatigue resistant, corrosion resistant and has high elongation. CUBE's Superlite tubes are double butted, giving very light tubesets with a high level of stiffness.
- Advanced Mechanical Forming - With Cube's Advanced Mechanical Forming technology they can mechanically transform different frame tubes and thus optimize them without material-wearing welding work for the respective requirements. Along the obtained organic look, the production method is primarily motivated by functional reasons. Multiple converted tubes enable them to manufacture lighter and also stiffer aluminum frames.
- Frame Safe System - To protect CUBE's high-end aluminium frames from damage, they are built with the CUBE Frame Save System replaceable derailleur hanger. The mounting thread is in the hanger and not in the frame as usual. In case of a crash, this hanger can be easily and quickly replaced by a new one.
- Integrated Cable Routing - Internally routed cables offer many advantages. Cables are protected from dirt for longer life, weight is saved thanks to the absence of external housing and the bike has a clean, sleek appearance.
- Press Fit BB - With Press Fit bearings, the bottom bracket bearings are pressed directly into the frame and not screwed in as usual. This gives a wider bottom bracket shell and allows us to build a wider down tube and more broadly-spaced chainstays. Every millimetre of additional width gives a significant improvement in lateral stiffness.
- Tapered Steerer - This steerer tube design is stiffer than a conventional straight steerer and yields a more secure ride feel even in difficult terrain. Minimal flex at the front of the frame means the greatest possible steering precision. With the larger steerer, the forks become more rigid. At the same time weight is saved due to the absence of bearing shells as the lower bearing is fully integrated into the head tube. On all of CUBE carbon models the upper bearing shells are also directly in the frame, so that once more a few grams are saved and the energy transfer is very direct.
- Wet Paint Surface - On polished, brushed aluminium and all HPC frames, the logos and graphics are applied in multi-layer wet paint. Cube use this surface treatment technology mainly to save weight.
