MIDDLEBURN RS7 SQUARE TAPER BIKE CRANKS

Middleburn RS7 Square Taper Bike Cranks are designed for riders who demand strength, precision, and smooth pedalling performance. Compatible with square taper bike cranks and JIS bottom bracket axles, these Middleburn RS7 cranks provide a secure, reliable fit for your bike.

Weighing approximately 434g (including lock ring), the RS7 bike cranks are available in lengths of 160mm, 165mm, 170mm, 175mm and 180mm, with a choice of sleek silver or black finishes. The 113mm bottom bracket axle gives a Q-factor of around 170mm and a crank arm clearance of 143mm, ideal for wider MTB tyres and modern frames.

First developed in 1991, Middleburn bike cranks have continually evolved. The Middleburn RS7 square taper crankset was introduced to accommodate wider MTB tyres, offering riders the perfect blend of clearance and performance.

Crafted from high-quality 7075 T6 aluminium, the RS7 cranks are hot forged, fully CNC machined, hand-polished, anodised, and then finished by hand. This meticulous process guarantees consistent strength, precision, and durability across every crank arm.
These square taper cranks come with a lock ring, and optional self-extracting bolts can be purchased separately. If you order a spider or UNO chainring with your cranks, we can mount it for you before shipping; just add a note at checkout.
