Pivot’s new LES SL hardtail: one of the lightest mountain bike frames ever

The latest Pivot LES SL arrives after years of R&D, creating one of the lightest production hardtail frames in the world.

The most aggressive full suspension mountain bikes with the latest technology are attracting a lot of attention. But a well-designed hardtail is still the weapon of choice in some areas. The format’s inherent simplicity and light weight make it a great rig from trails to pump tracks.

Pivot’s new LES SL fits the bill. The new bike frame weighs just over 800g in a size medium. The brand wants to offer runners savings in critical weight to save seconds and save energy.

Pivot engineers shaved 300g off the LES SL predecessor (same name, different bike). Ten kg is a benchmark weight for a hardtail frame – 800g is the gold standard.

Optimizing the carbon layup helps the bike stay light and improves speed, ride feel and performance over the previous generation.

The geometry of the LES SL seems to deliver plenty of power to the ground while offering racy handling and liveliness with enough vertical compliance to keep you on track and feeling fresh for the long haul.

It uses a more extended reach (about 17.5 inches in a bracket) and a slacker seat angle (74.5 degrees on most sizes).

Chris Cocalis, CEO and bike designer of Pivot, spoke about the central challenge the design team was looking to solve: improving a simple machine without adding any embellishments.

“Our LES SL really shows our commitment to innovation,” said Chris Cocalis, Pivot CEO and bike designer. “There’s no place to hide with a hardtail – the simplest machines are often the most elegant and the most difficult to design.”

“Bringing this bike to the next level took extra commitment from our team. They really nailed not just the weight, but the performance, and the ride quality is absolutely amazing.hardtail racing pivoting
