Bombtrack Arise SG Apex Gravel Bike

The Bombtrack Arise SG Apex is a double-butted 4130 chromoly gravel bike with sliding thru-axle dropouts, so it can run geared or be converted to singlespeed later. SRAM's Apex 1x11 drivetrain pairs a 40T narrow-wide chainring with an 11-42T cassette for a wide spread of gears, and Tektro Mira mechanical discs keep roadside servicing simple. Size-specific wheels put 650B on XS and S frames and 700C on M to XL, both on tubeless-ready WTB rims. Rack and fender mounts plus internal dynamo routing make it a practical year-round bike for New Zealand gravel and commuting.

Who Is the Bombtrack Arise SG Apex For?

This is a straightforward, hard-wearing gravel bike for riders who value simplicity and the ability to fix things themselves. Mechanical disc brakes can be adjusted with a hex key at the trailhead, the 1x11 drivetrain has no front derailleur to set up, and the sliding dropouts leave the door open to a singlespeed commuter build down the track.

For New Zealand riding it covers gravel roads, rail trails and the daily commute without complaint. Steel handles rough metal surfaces well, the full mount set takes mudguards and racks through winter, and internal dynamo routing is ready if you want permanent lighting. The 11-42T cassette gives enough range for loaded climbing.
