Mount Vision Suspension bolts keep working loose – how to tighten?

Sounds a really obvious question but I’ve used a torque wrench and followed the manual’s instructions and ensured they are tightened to the required tension 18 newtons…I’ve made sure the bolts have equal spacing either side but after about 2 miles of biking, the lowest link is proper loose – can be wobbled back and forth and when you pick the bike up, the back end drops noticeably.

So I now ride around with a ratchet and the tools to remove the topcaps, keep the linkage in place and tighten the bolts…but it’s getting properly annoying now as it’s ever ride and now more than 1 stop on the bike.

I’ve tried some threadlock on the threads and still nothing…what else can I try to ensure the suspension stays tight and doesn’t work loose…

Thanks.

Clean and dry threads then plenty of Loctite 243 and torque them up.

Same as above but let the loctite cure properly before using the bike again.

Loctite had about 72 hours of curing time…strangely enough the bolt that had worked loose today when I went to tighten it had no signs of the loctite on the threads…it was a bright red colour and the other bolts all showed signs of it still there…

Did you miss one perhaps ? Give it another go.

Definitely not missed…being the saddo that I am, I marked all 8 bolts on a piece of paper then crossed each one off as I covered it in Loctite and put it back on the bike…so defo not missed…but it’s so annoying now…been like this for the last 2 months and I’ve had enough of it…

Get a decent bike shop to check it for you , could be a problem with the threads in the linkage.
Is there any play in the linkage when you’ve retightened it ?
