I'm looking to build up a Surly Streamroller. Was thinking about building up with Soma parts --- in particular -- the Soma Hellyer crankset. How good are their products? I'm not looking for anything fancy but I don't want parts to fail. I'm commuting a little over 10 miles daily --- and would like to make this my winter machine (throw on some beefy studds!). Any opinions on Soma (or other cranksets under $150) would greatly be appreciated.
