BROTHER CYCLES PINECONE FRAME - COMING SOON!

Meet the Pinecone — Brother Cycles’ brand-new, all-steel, all-terrain frame inspired by the rugged charm of retro mountain bikes from the ’80s and ’90s. Designed for adventure, commuting, and good times on two wheels, the Pinecone blends classic MTB geometry with modern versatility, creating the ultimate do-it-all frame for riders who value fun, simplicity, and freedom.

Built to Ride Everywhere

The Pinecone’s geometry hits the sweet spot between agility and stability.

• 440mm chainstays keep it quick and nimble when the trails get tight.

• A 70° head angle adds confidence on varied terrain.

• The skinny 4130 chromoly steel tubing provides just the right amount of flex for a smooth, forgiving ride.

Heat-treated and ED-coated for strength and corrosion resistance, this “Extra Tough” frame feels lively and responsive without being harsh — a true homage to classic steel bikes with a refined modern touch.

Retro Look, Modern Function

With a level top tube, quick-release dropouts, and a 1 1/8” headtube, the Pinecone oozes retro MTB style — but don’t be fooled by the vintage look. This frame is packed with modern features to make your ride more versatile than ever.

• Wheel compatibility: Designed around 650b wheels with clearance up to 2.6” tyres (depending on brake setup).

• Brake options: Choose between cantilever, V-brake, or disc (51mm I.S. mount) — the Pinecone gives you total flexibility.

• Drivetrain setups: Run it single-speed with the horizontal dropouts or geared using the included derailleur hanger insert.

• Front end: Tough segmented fork with triple mounts on each blade for cargo cages or racks.

Perfect for mixing new and vintage components — go ahead, dust off that old XT groupset or those classic V-brakes you’ve been holding onto.

Adventure-Ready Mounts

Carry more on every ride with:

• 3 x bottle cage mounts

• Fork triple mounts for Anything Cages or extra bottles

• Rear rack and mudguard mounts

• Ample chainring clearance for triple, double, or single setups
