Strengths:    One of the few stainless steel granny rings available

Weaknesses:    Not good enough

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.

Strengths:    Aptly named so you know what to do with it after it breaks.

Weaknesses:    Strength/durability

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. I'm guessing the same QA dept. is used for their website and products.

Strengths:    Amaysingly durable

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.

presta valve chuck for air compressor

I can't get my 29'er tubeless rear tire to re-seal after a flat. I saw a bike mechanic's set-up and he had a presta valve chuck attached to his air compressor. I asked where I could buy one and he didn't know. I guess he wants me to bring the tire to him to fix. Anyone have any ideas about this? I'v ... Read More »

Karate Monkey: Chuck Taylor of Modern Mt Bikes?

The KM is having a good long run, and when thinking about it, I couldn't think of a peer in the "Chuck Taylor" of mt bikes category. I know, like we need another 'category', but since the 29er era got going, this seems like the one constant. How do you guys see it? I'd go a step further and give ... Read More »

To those who have made Chuck Lennon what it is today.

Thank you for the most fun I've had in a long time. That is an awesome trail. I haven't been on a single track in nearly 25 years when I was a young boy riding my BMX on the local motorcycle trails. Chuck Lennon was 100 times more fun than that ever was. I got my new Airborne Skyhawk Friday, got ... Read More »

Cheap Presta Chuck that works great!

Just thought I would share this in case someone else is looking for a chuck for presta valves. All my bikes are presta now so I searched and decided just to do this rather than buy all kinds of parts . Forgive me if this has been done before but I searched and didnt find anyone doing it this way. ... Read More »

This tire chuck made going tubeless sooooo easy...
