The timeless charm of a caliper brake now combined with the benefits of oversized tubing. “Caliper SLX” gets its namesake from the famous Columbus tube set which, in the 1980s, raced alongside hundreds of professional teams, who were often in yellow, pink and rainbow jerseys! Within the Futura fork range, “SLX” specifically refers to our brand new models for 1-1/4” oversized steerer tubes. After the 1-1/2” tapered, and the classic “SL” 1-1/8” steerer tube versions, this new option enriches and extends our range of forks. Some framebuilders suggested adopting this steerer tube diameter (oversized, conical, but with contained proportions) to combine the benefits of larger diameters with more elegant lines and shapes, which you often see on metal-alloy frames. Additionally, while retaining the possibility of selecting the desired rake (45 or 50mm) to better meet each cyclist and framebuilder’s geometry needs.
