Velo Orange Grand Cru 50.4bcd Cranks MK2


There’s been small changes to the classic 50.4mm BCD cranks MK 1. They have improved chainrings which are  30/46 teeth and there is now more room between the arms and chainrings for easier front derailleur setup. The arms are also stiffer but a tiny bit lighter.

Classic 50.4 BCD cranks, like the TA, Stronglight 49D, and others, are still sought after by randonneurs and cyclo-tourists. These cranks offer tremendous versatility (chain rings from 28t to 62t fit). They are also light and have narrow Q-factors, or tread.

While the new Grand Cru crank looks like the classics, there are several important improvements. They are cold forged 7075 aluminum alloy. The rings are thicker so they don’t flex as on classic cranks. The BB taper and all threading is common sizes (fits square taper BBs) – no need for special tools and BBs. The rings have modern shifting aids, so shifting performance is much improved.

Here are the highlights:

  • Cold forged.
  • 46/30 rings which offer the range of a triple with less shifting and lower weight.
  • More room between outer ring and crank arm for easier front derailleur setup.
  • Thicker chain rings for less flex than TA or other classic cranks.
  • More VO chain rings coming later, or you can use TA rings.
  • 7075 alloy CNC cut rings for super durability.
  • Shifting pins on chain rings for faster shifts compared to classic rings.
  • 5-10 speed compatible.
  • All-stainless hardware. All bolts/nuts are Allen head.
  • Standard extractor/dust cap thread, standard ISO pedal threads.
  • High polish finish.
  • Aluminium machined dust caps included. BB bolts included.
  • Shifts well with double or triple front derailleurs

About bottom brackets: Most road frames use a 118mm BB. Bikes with 135mm spacing and room for big tires may need a 122 BB with a spacer.

Available in 165mm, 170mm, and 175mm lengths. In stock sizes are shown in the drop-down list.
