Previously to Tangent producing their Halo 5 Bolt Square Taper cranks, if you were looking for any three-piece crank shorter than 120mm, your options were pretty slim, and costly. Tangent has hit the sweet spot here with these 100% CNC cranks.

Starting from 100m, these cranks are machined from 7075 aluminium and go right up to 160mm in length. But keep in mind is that they have a 45kg rider weight limit. That’s the trade off for lightness.

Specs:

• 100% CNC 7075 Alloy Arms and Spider
• Pedal Offset for Wider Frames
• 45kg weight limit
• 5 Bolt 110BCD (Tangent and Rennen chainrings only)
• BB Sold Seperatly
• Weights:
• 135-375gm
• 140-380gm
• 145-385gm
• 150-390gm
• 155-400gm
