Beautifully hand machined, lovely fluting up the sides. Looks like at some point in the past they've been fitted with a BB thats a bit short so there are some marks on the back of the cranks, obviously you'll never see them as they're on back, they look much worse than they are.

Topline also produces a road bike version of their crank arm set. They are made nearly the same as their famous mountain bike cranks. Each of the arms is turned on a lathe making the smooth and rounded shape. The backside of the arms, like the Mountain arms, is milled away slightly. This is so the right arm doesn't interfere with the front derailleur. The top and bottom of each arm is milled with a groove that gradually widens as it moves from the pedal toward the bottom bracket. These grooves reduce the weight of the crankset. The spider is machined from 6.32mm thick aluminium plate. The primary difference in these cranks, naturally, is the spider. On the road version, because there is no inner chainring, each of the spider arms has the center milled away from the top. The road cranks have same pedal fitting, where the pedal ball is drilled and threaded without piercing through the backside of the arm. These are elegantly fashioned while loosing none of their utility, and will give any bike a functional, one-off appearance. Topline Road cranks use the 130mm chainring bolt pattern and do not come with chainrings, chainring fixing bolts or crank arm dust caps (Sims or Cooks are recommended). These you will need separately. The Road arms are made only in Black or High Polished Silver and come in 170mm, 172.5mm, 175mm, 177.5mm, or 180mm lengths. We found the Road arms to have a Bike-Pro Q measurement of 150mm. The 170mm arm set, with spider in Silver weighs just 363 grams, the 172.5 set weighs 369 grams.
