What chainring guard and where?(3 posts)

I have a new 105 crank. Can I use the 39 tooth chainring it comes with and run a chainring guard? If so where can I get these. Also, should I get a 3rd eye chain watcher? Thanks in advance!

I run double TA guards (from Cyclocrossworld.com, which carries a good selection) and a 42-t ring on a 105 crank. I do have to use the longest spindle bottom bracket Shimano makes to clear the inner guard off the chainstay (and just barely at that).

Chainring guards -- at least the TA ones -- do come in specific sizes to go with particular chainrings. Too big, and it will rub when you're on the high or low cogs in back, too small and it won't keep the chain on as effectively.

If you're going with a single guard, I don't like the 3rd Eye chainwatcher (it's just too flimsy, and I've discovered to my chagrin that it's possible to yank the chain past the 3rd Eye, at which point it does a bang-up job of keeping you from getting the chain back on). I have heard good things about a different product called the Jump Stop (a google search should turn up the site).

if you go single ring you most likely will want a 42. Go like the previous poster and run the double TA set up. You can get the whole kit from cyclocrossworld. otherwise get a single and a jump stop or 3rd Eye. I've had no trouble with my 3rd eye but have heard the stories.
