@william nice to read your happy with the light. I have both the Trace (front) and TraceR (rear) lights. Although the rear mount is slightly angled to help correct the light position the two lights use essentially the same mounting method and rubber band. Is what I call the rubber band what you refer to as the silicon and/or black band?
I have used both extensively for two years without any incidents. I do agree it seems the band is stretched a lot but I haven't found it a problem. I mount the lights in one of three different ways, each using the rubber band, depending on the bike I'm riding. For options #2 and #3 you'll need the relevant mounting points on your bike.
- With the supplied mounting and band on the bars and seat post
- Using the Restrap mount linked below £6.99, mounted as illustrated on my offside fork
- Using the Race Ware mount linked below £25.00 mounted on the offside seat stay. Although not required I use the band for extra security with this mount
In my experience the Restrap mount is every bit as good as the Race Ware mount. If you have a very specific mounting issue Race Ware used to offer a service to produce individual, bespoke mounts. A friend used this service, very expensive, but solved his problem. I don't know if the service is still available. From what I gather Race Ware offer mounts which cover a huge range of situations. The mounts are 3 D printed.
