Hello everyone,

I have a Norco LRT 1, with an FSA Dyna Drive Trek chainset 48/38/28t installed. As the bike is now 2 years old, the pre-installed plastic chainring recently snapped off while I switched to my high gear the other night. I am now looking to replace this for peace of mind, so I don't have an open saw blade spinning next to my leg possibly catching on my pants. I did some research and found that there are a couple options available to me:

1. Getting a chainring on top of the big ring, to protect my leg. I've only been able to find this chainring available. This will offer some protection to the sprocket itself, but increase the overall profile of the chainset, and I'm not sure if it'd be overly bulky.

2. Replacing the big ring with a heavy duty bash guard sized for the middle ring, 104bcd 38t. This will lower the profile of my chainset, protect the gear sprocket, and have less bulk. However, this is at the cost of my high gear, making higher speeds on flat roads or slight downhills less efficient.

Please let me know what you all think!

I have a converted 1x9 setup using 42 tooth single speed middle chainring with an E13 outer bashring, which suits me perfectly. It can be tough finding one of those outer chainguards because a lot of them are proprietary and are not often sold separately even if they came with the bike. I wanted one, but couldn't find any that worked with my crankset.

It is possible to put a bashring on your existing setup, but the bashring has to be thin and you will need chainring spacers and fairly long chainring bolts about 16mm length, which I might add are hard to find an expensive. More work than it is worth for any kind of gain. My suggestion would be to try and find that outer bashguard first and if you can't find a replacement go with the bashring and sacrifice a little top end speed.

Why not just get one of the neon straps for your pants? Really, the big chain rings offers no problems other then on pant legs but a simple solution is a neon strap!
