The appeal of Surly's modular crankset is that it can be configured to suit any bike and there’s a good choice of Surly or Salsa chainring/bashguard combos. Like most Surly products it’s cautiously overbuilt to take a fair amount of punishment.
But this much versatility doesn’t come cheap. By the time you add a couple of rings and/or a bashguard to the crank arms (£120), spider (£65) and axle (£60) you're looking at about the same price as the complete triple setup (£320), and you still need to buy (Shimano cup compatible) bottom bracket bearings.
The weight of our 33/22-tooth, 175mm arm double setup is fairly reasonable considering the fact that we used a stainless steel outer ring. A hefty chromoly steel axle emphasises Surly’s design attitude: this is a crankset that's intended for heavy-duty cross-country use and a long multi-bike life, and our experience is that it does the job.
Bear in mind that while the five-arm spider offers a good choice of rings from sister brand Salsa as well as Surly, most other cranksets these days are four-bolt.
