      FavoriteTrail: The one I'm on
      Duration Product Used: Less than 1 month
      Price Paid: $15
      Purchased At: LBS
      Strengths: One of the few stainless steel granny rings available
      Weaknesses: Not good enough
      Similar Products Tried: OEM Steel granny; Truvativ Firex granny; Truvativ Stylo Granny; Cycle Dynamics Ti granny
      Bike Setup: Truvativ Stylo; Wipperman chain
      Bottom Line: First off, I need to say that I weigh around 240 dressed (and I bike dressed). Second, ever since I got a Wipperman Stainless Steel chain, I've been burning through granny gears like they were made of cheese. I ride on sandy, muddy trails and I guess the combination is too much for these rings. The Blackspire began to suck after about 4 rides (8 hours)! This may not be a problem for a rider under 200lbs.

      I've been riding a Cycle Dynamics Ti granny (about twice the money) for about 4 months and so far, no problem.

      Date Reviewed: 6/30/2003 3:51:01 PM
      Duration Product Used: 6 months
      Price Paid: $15
      Purchased At: Somewhere in Vancouver
      Strengths: Aptly named so you know what to do with it after it breaks.
      Weaknesses: Strength/durability
      Similar Products Tried: other crappy chainrings
      Bike Setup: new Heckler with XT hollowtech cranks and Sram chain.
      Bottom Line: I'm guessing it's called a chuck ring as it chucks the chain onto the BB shell and now I'm going to chuck it in the garbage. I'm not a punishing rider but this thing bent during a cross-country ride. I straightened it but it easily bent again on each of 3 subsequent rides.

      I had bad luck with Blackspire rings in the past but hadn't tried them for a few years. No more cash for them.

      How fitting. I just took a look at their website and though they claim to be Canadian their main page statement sounds like one of those old Taiwanese company ads in MBA. http://www.blackspire.com/main.html I'm guessing the same QA dept. is used for their website and products.

      FavoriteTrail: Trials
      Duration Product Used: 1 Year
      Price Paid: $15
      Strengths: Amaysingly durable
      Similar Products Tried: aluminum crap that wears out in a month
      Bike Setup: Norco Team Trials, black spire cranks, seatpost, granny god.... HS33 brakes
      Bottom Line: Well, since I am always in my granny ring because I ride trials, it gets alot of wear. I ride just about every day of the week for several hours. After a year of use, I am really pleased to say that this ring is the bomb. It apears to have no wear at all... Great product.
