As of today at 10 a.m. GMT, pre-orders for the updated 2021 Big Bro from UK-based Brother Cycles are now open, and they’re expected to go fast. Made from double-butted 4130 chromoly steel, the Big Bro is the small brand’s all-purpose 27.5+ or 29er adventure frame, with clearance for up to 27.5 x 3.0″ or 29 x 2.6″ tires. It features discreet dropper routing, rack mounts, provisions for three bottles, and three-pack mounts on the 100mm suspension-corrected rigid fork. Run it geared or single speed with its replaceable thru-axle sliding dropouts.

New for 2021, it’s now offered in a bold yellow paint job alongside last year’s forest green, and it features Boost 12x148mm/15x110mm spacing, opening it up to more wheel and tire options. Otherwise, the specs remain unchanged. Pricing is £675 ($945) price tag including UK VAT or £562.50 ($785) for customers outside the UK. The Big Bro is available in four sizes: small (16″), medium (18″), large (20″), and extra large (22″). Framesets are due to arrive around the end of this month.
