Esker Solitaire is a limited-edition, rigid steel 29er built for single-speed use but compatible with wireless 1x drivetrains and 120mm suspension forks. The frame features a slack 67.5° head angle, steep 74° seat angle, suspension-corrected steel fork specification, and generous clearance for large 29er trail tires. Long, adjustable chainstays allow chain tensioning for single-speed setups while supporting alternative drivetrain options. Multiple mounts and durable construction permit bikepacking and serious off-road use. The bike presents classic klunker aesthetics with modern trail-ready geometry and is offered in a single sparkly red paint.

Learn More Esker Cycles has a sweet new rigid steel, singlespeed-friendly bike for the discerning mountain biker looking to blend classic klunker looks with modern trail-ready geometry, plus all the good new standards. But it is seriously limited, so if this looks like your kind of ride you should probably put your chips on the table fast before they are gone.
This is a rigid 29er with a slack 67.5° head angle, steep 74° seat angle, and a suspension-corrected steel fork (=120mm). Plus, room for the biggest 29er trail tires you could dream of. And if you want to think of it like a bikepacking rig, Esker gave it all the mounts and built it to take some serious off-road abuse.
Sure, it features long chainstays, made adjustable to tension your single-speed chain. But you could also mount one of the many great wireless rear derailleurs on the market and not have your knees suffer on the climbs. Or build it up with 1 gear now. Knowing that you can always chicken out and slap a wide wireless 1x setup & 120mm suspension fork on there when your body craps out.
