Review on 🚲 Enhance Your Bike's Performance with Sigma Butler STS 2450 Comp Part Front Mount by Gary Stringfield

Sigma mounts for Rox 9.1 and lower numbered products (except Rox 10) do not have a long lifespan. Let's see how it holds up. Much better visibility than the previous stem mount, barely long enough for a standard mount. Much better for a quick background check if using Rox 9.1. The only reason for 4 out of 5 and not 5 is that historically Sigma mounts for this device have not been durable. Let's see how well this holds up over time. I love that I can mount this in front of the steering wheel, in front of my hands. The ergonomics are perfect.
