Bombproof Bike



Over at Blue Collar Mountain Biking there’s a discussing about a “Bullet Proof Bike”. When I read the title I was already imagining an oversized, ultra strong velomobile but it appears they are going for a very durable bike, low cost, low maintainance but still high quality. Something to keep track off…

These are the specs they started of with:

  • Frame/Fork: Surly Insigator frame and fork
  • Crankset: Shimano FC-MC20 with 104/64 BCD rings, square taper BB compatible or Sugino XD-300 square taper BB compatible with 110/74 BCD rings.
  • Bottom Bracket: Shimano UN-53 118mm spindle or SKF equivilent
  • Shifters: SRAM MRX-Comp grip shift type 7spd
  • Hubs: Shimano Deore front and rear
  • Cassette: Shimano 13-34T 7spd.
  • Chain: SRAM PC-48 with Power Link
  • Rear Derailleur: Shimano Deore
  • Front Derailleur: Shimano Deore
  • Brakes: Tektro linear pull
  • Levers: Tektro linear pull compatible
  • Cables/Housings: Jagwire or equivilent
  • Seat Post: Kalloy (cheap, does the job)
  • Handle Bar: Dimension or equivilent (See seat post for why)
  • Stem: Ditto above
  • Saddle: Personal preferance (WTB has a commuter saddle in it’s line up)
  • Grips: Personal preferance (Suggest we get some from Ergon)
  • Pedals: Personal preferance
  • Rims: Laced to a Sun Rhynolite, Salsa Gordo, or equivelent rim

ps: the image shown is a Norco A-Line bike that showed up when I googled for “bombproof” and “bike”….
