bing Posted September 23, 2012 Author Report Share Posted September 23, 2012 Maggy mounts are usually stripped when people tighten the bolts too hard ? you can't argue that is it is very easy to strip a thread on a modern trials frame, due to the quality of the metal. you don't even have to tighten the bolt down that hard, regardless of the level of retardation. just sayin like Quote Link to comment Share on other sites More sharing options...

If you stripped thread in your frame - it's not a big problem. Edited September 23, 2012 by clerictgm Quote Link to comment Share on other sites More sharing options...
bing Posted September 23, 2012 Author Report Share Posted September 23, 2012 (edited) I'd take a small unnoticeable weight gain, for the longevity of my frame any day. if you can notice 50-100grams of weight, which is a medium size bag of crisps, on your bike, I'll show my arse in tesco's window. go and weigh 4 helicoil inserts, bet it's not even that much Edited September 23, 2012 by bing Quote Link to comment Share on other sites More sharing options...
ULtrialsguy Posted September 23, 2012 Report Share Posted September 23, 2012 Could be my old beast of a frame but I've never stripped the threads and I tighten bolts as hard as I can. Quote Link to comment Share on other sites More sharing options...
Blake Posted September 23, 2012 Report Share Posted September 23, 2012 The only way i've stripped threads is where the bolt goes in and out so much the threads get all warped and soft, and crossthread really easily then just strip :/ Steel inserts would be a lot better IMO, just for peace of mind.

If you stripped thread in your frame - it's not a big problem. Random picture of frame.... Anyway I've just stripped my echo the other day just from having a very tempermental clamp set up that the slaves move in unless being extremely tight , and echo don't really have the best threads I've come across Quote Link to comment Share on other sites More sharing options...
Blake Posted September 23, 2012 Report Share Posted September 23, 2012 Also I wish more frames were made like the onza limey (original green and white one) Because the underside of the magura mounts are square, if you do accidentally strip the threads you can run extra long bolts and run a nut on the flat side of the frame, genius design.

Luke Rainbird Posted September 23, 2012 Report Share Posted September 23, 2012 If you're stripping threads you have several options. 1. Don't be such a f**king mong. 2. Helicoil 'dem bitches. Quote Link to comment Share on other sites More sharing options...
bing Posted September 23, 2012 Author Report Share Posted September 23, 2012 (edited) I'm not saying everybody is a Mong, just thought steel inserts would be a good idea from the manufacturer, and presented my reasons why. that was the idea why I created this thread. back to it, rims with a cnc'd sidewall so you don't have to attack them with a grinder straight away Edited September 23, 2012 by bing 1 Quote Link to comment Share on other sites More sharing options...
bike_dummie Posted September 23, 2012 Report Share Posted September 23, 2012 With modern frames stripping threads shouldn't be a problem as its more likely to have cracked before you go through the original thread and a helicoil or alternatively you could use the stud and nut method?

SamKidney Posted September 23, 2012 Report Share Posted September 23, 2012 (edited) Isnt the answer easy to this? Threads strip when "over tightened", generally because theyres no grease on there (in most cases) The increased friction from dry fitting the bolt increases this risk, because as the bolt tightens, and starts to pull against the threads, the lack of lubrication tries to turn the frames threads, being a softer metal, with the steel bolt. Voila, you have a stripped thread. I know this. I almost stripped my 24"s threads (brand new). Applied some lithium grease to the frames threads, and tried again. Result; I can now torque down my clamps further than before, with very little fiction induced resistance. No stripped threads, tight clamps, reliable brake. Applied it to all my bolts on my bike now. Everything's nice and tight, no creaking, nothing coming loose or shifting, lower chance of stripping the threads. Win win. Not a fan of the idea that companies should fit steel coils as standard. Frames are not the cheapest things as it is. Adding another process would only drive up the price. And if you pull out that coil, your forced to go to a larger thread. Having aluminium threads, means that if you strip them, you have another shot at running an M5 thread through helicoiling it.

bing Posted September 23, 2012 Author Report Share Posted September 23, 2012 as most frames have the mounts welded on, and are probably outsourced to be made in the first place, surely it wouldn't take much to press and bond in a steel thread insert. then weld the brake mount on. I'm with you Sam on the 24" tyres thing, try all would clean up in that market. dmr's are too floppy, and puncture very easily. maxxis are far too heavy, as I found out with my 2.7 high roller Quote Link to comment Share on other sites More sharing options...

Other wise we'd see a wide majority of frames with identical mounts. My Echo's mounts are cnc'd to match the style of other cnc'd areas of the frame.

Sam Moss Posted September 24, 2012 Report Share Posted September 24, 2012 Have a search on google for a "one way roller bearing" they can only spin one way and have "unlimited" engagements. I just think someone should make a freewheel like that. People have already made hubs like that but they are pretty heavy and expensive.

craigjames Posted September 24, 2012 Report Share Posted September 24, 2012 just use discs there better "They're". But if you rode a bike with proper size wheels you'd understand that discs aren't a lot of kop for stocks. A little finesse wtih your tools and some properly installing parts goes a long way to stopping things from stripping/ cross threading.

Revolver Posted September 24, 2012 Report Share Posted September 24, 2012 It's not a random picture of a frame, threads are stripped and problem solved by this: That picture appears to show a brake where the pad is set half way off the rim. 2 Quote Link to comment Share on other sites More sharing options...
ghostrider88 Posted September 24, 2012 Report Share Posted September 24, 2012 Only retards strip threads - FACT It´s not that hard if magura mounts come with short bolts like first ECHO mounts...But with right lenght and little grease, yes, it´s not common.
