The Tag Metals T1 Aluminium Stem in 35/45mm diameter and sleek black color is a top - notch choice. Tried and tested by the ultra - precise Nicolas Vouilloz, it's as reliable as it gets. Crafted from CNC machined 2014 T6 alloy, it features a 4 - bolt clamp that firmly grips your carbon or alloy bars. The SAS (Speed Align System) allows for accurate bar angle adjustment, and the TAG Speed Adjust bar markings make the process even easier. With 35mm/45mm stem lengths, 2 opposing steerer clamp bolts, and a 35mm clamp size, it's both functional and well - designed. Weighing 181g (35/35) or 221g (35/45), it's a great balance of lightness and durability.

Using the Tag Metals T1 Aluminium Stem is easy. First, select the appropriate stem length (35mm or 45mm) for your needs. Install it on your bike and use the 4 - bolt bar clamp to secure it firmly to your carbon or alloy bars. Adjust the bar angle with the help of the SAS (Speed Align System) and the TAG Speed Adjust bar markings for precise alignment. When it comes to maintenance, keep it clean by wiping it down regularly with a soft cloth. Avoid using harsh chemicals as they may damage the finish. Check the bolts periodically to make sure they are tightened properly, but don't over - tighten them as it could cause damage to the stem or your bars. If you notice any signs of wear or damage, it's best to replace the stem to ensure your safety while riding.
