Steerer tube slipping in the crown
My mate has a set of Toras which either through man handling or a bad crash are basically ready for the bin now.
The steerer tube slips in the crown of the fork meaning the bars and stem turn out of line with the front wheel when riding down a trail.
Is there anything that could be done to the fork to get the steerer and crown solidly "welded" together again? It takes the amount of torque generated by holding the wheel between your legs and pushing & pulling with not that much force on the handlebar ends to get it to slip. He's already replaced them but I was just wondering what could be done with the old ones other than sold for sparesPosted 7 years ago
What would be wrong with that PP? The steerer is stepped at teh bottom so cannot pull out upwards. Loctite is commonly used in this sort of application. You are not removing strength from it in any manner. The steerer is only a press / interference fit in the crown anyway.Posted 7 years agostomMember
If the Steerer's twisting in the crown you've plastically deformed the crown or steerer tube.
Applying Loctite is only going to be a short term fix – if the crowns already deformed it's going to deform further under load! Loctite is meant for bonding components together with carefully controlled tolerance's, not for sticking together effectively bent components.
Drilling and bolting the components together is even worse. Your then removing material from the fork crown when you drill it(an already highly stressed component), and effectively creating a stress riser(weak point) in the component from which micro cracks can propagate and cause structural component failure.
Persoanlly i'd put the forks in the bin ASAP otherwise you could be heading for a really nasty accident if the crown or steerer tube fracture.(i've witnessed failures of this type at a race a few years ago. Trust me you don't want it to happen to you it -it was pretty grim!)Posted 7 years agobarrykellettMember
He'd already replaced them before I posted with some nice Vanillas, I was wondering if there was anything that could be done but was pretty sure they were never to be used again.
Definitely was not the stem moving, 100% it was the steerer slipping in the crown.
Not to worry. Will probably sell as spares.Posted 7 years ago
