I have used it for few months.
I haven’t had a very hard impact on the bash guard yet, but I had one light scrub, which barely gave a mark, but once I get a big impact I will update you on this.
The bash guard is mounted with two Torx screws to into the plate, which makes assembly and disassembly is very easy & fast, there is no need for two Torx screws like with MRP AMGv2, but the only bad thing about this is if you ruin the threads, you cna’t just swap bolts, but it keeps the weight down.
- Doesn’t clog up with mud, 77designs designed a great chain guide, it does the job well, without any unnecessary bulk or material, mud will travel through the big hole.
- easy to take the chain off, due to the simple and great design of the guide, you just undo the bolt little bit and swing the front guide, with Loctite 243 and proper torque it will stay on securely.
- the chain guide from 77 Designz seems to be good, with keeping the chain in place, I tested how well the chain will stay on by forcing it off the chainring, the plastic pushed it back on, so I think the chain will be very secure on the trail no matter how fast or hard you ride. I think it does a better job than MRP AMG v2, which is not really made for oval chainrings.
Broken Bash plate
First I used 34T oval, which the guide supported but for this chainring size the bash guard could be few millimetres longer, to protect against very uneven stone edges, but I later switched to 32T Oval and that should not be an issue for sure, I have also ordered new bash guide plate, the size was 28-32T which was exactly the same as the original.
I will update you on further developments.
