There are a new crop of XX1/XO1 bikes out now that use a narrow-wide single chainring up front with a clutch derailleur in the rear. This setup doesn’t require any chain retention help, but it does leave your ring/BB area vulnerable to rock/log impacts.
XX1/XO1 don’t play nice with traditional crank mounted bash rings and using a full ISCG chain guide just to get the taco style bash portion is a waste plus it adds back a bunch of weight you paid through the nose to get rid of.
There are some Taco only bash guards, but until I found this Blackspire Bruiser they were all made for the bigger rings we were using on double/triple ring bikes so they hang down too low [ie. MRP XCG].
The Bruiser was purpose built for the smaller XX1 rings and works with 26T-32T. There is also a 32T -38T model if you need a bigger ring. It is light at 76g for the smaller ring version. Low profile and best of all made in Canada. Cost is $60 CAD so that’s like $20USD or something? 😉
I ordered 2 for Sharon and my Pivot Mach 6 mountain bikes. We’ve been using them nearly 6 months now and they have performed as expected.
