So you need a new chain — do you seek out something new and different, or stick with the same model you had before? It’s easy to just grab the usual SRAM or Shimano chain and keep on rolling, but Connex is hoping you’ll mix it up and go for something like its 11s0 chain, which we tested last fall.
Perhaps the only bike upgrade that is less sexy than a chain is a bottom bracket (well, the word “bottom” does have some humorous, juvenile connotations), but replacements are inevitable. As for the Connex 11s0, it worked flawlessly for 700 miles of riding — mostly cyclocross, including 14 races. The shifting was on par with any Shimano, KMC, or SRAM chain we’ve used before. Plus, the Connex withstood a punishing, muddy day that resulted in a decapitated rear derailleur. We just kept on riding it for another month of ’cross racing.
Connex’s only quirk is the quick link. It works perfectly well, but it must be oriented correctly, or the chain will skip in the 11-tooth cog.
Here’s the one knock against Connex: This chain is $70, which is rather dear, compared to SRAM’s PC1170 chain, priced at $46. The two are roughly comparable in terms of weight (the Connex weighs 270g for 118 links) and performance.
If you’re feeling adventurous and need a new chain, we can vouch for the Connex, but it’s a little hard to discern if the higher price is worth it.
