[Closed] E13 TRS vs TRS+ double device?

I was looking at these myself for the FS. Think TRS is steel and TRS+ is alloy. That's it. Just bought and fitted a Bionicon C Guide for £29 from Evans on the HT as a test. Lighter and cheaper still.

Thanks. I'm really after more of a bash than a chain guide, so whilst the TRS is overkill and expensive, my options are limited as I bought a 2x10 crank rather than 3x10.

I went from a full bash guard to a TRS+.
I was concerned it wouldn't be as durable, but I haven't broken it yet.

Done, ordered the TRS cheaper version from Bike-Discount
