Ergon LS100 Handlebar Reinforcement – Reviews

A 99% well thought-out product. I love the way it applies the necessary reinforcement by actually applying a legitimate hard force; the green “screw” when torqued compresses inward, but it’s overall shape is triangular… and the surrounding walls are have a diagonal angle as well… meaning if you torque it in, it will force the walls outside by sliding, instead of the usual expansion via rubber (e.g. Hope Grip doctors ([...]))

The particular type of reinforcement offered by this approach allows you to actually torque to the bar-end spec regardless of your handlebar type. For example, my Easton carbon handlebars are rated 4Nm at the ends of the bar. The Ergon GX2 grips I use torque should be torqued to 7Nm. Without the plugs, I would have to torque it to no more than 4Nm to prevent cracking the bars…. but because of the plugs (and I confirmed with Ergon support) that you can torque to the 7Nm requirement if you use these plugs. What I do to be on the safe side is to use carbon compound so I can under-torque to say 6Nm just for peace of mind.

It’s 99% (the same reason I’m not giving it full stars) because while it is very effective in the application it was designed to do, but the “reusability” aspect wasn’t well thought out.

The “wings” you see are what I would call “torque handles” these make sure that you don’t have the contraption twisting along with your torque-ing – thus ensuring that it’s torquing properly. It seems sensible enough that they put something like that in, but they were designed to be broken off after use. And you have spares in case you change handlebars… which kinda assumes you’re only going to have 2 handlebars in the course of using these things.

It’s not that much of a big deal since you can still torque it without the wings given it’s not a “rubber expansion” based plug (torquing the Grip doctors was hell, but then I don’t think they were really designed for this type of bar reinforcement); but I just couldn’t help but nit-pick about that particular aspect.
