Mark James Posted February 18, 2021 Share My hex screw/bolt holding my XTR shifter on the handlebar snapped off (at about the 2nd/3rd thread) when trying to unscrew it today. Would anyone know if this would be covered by the Shimano guarantee in South Africa? I saw online that the EU guarantee is 2 years on all Shimano components, and 3 years on Dura-Ace/XTR components... The bike is a 2020 Merida Ninety-Six 9000. Would a regular bike shop selling Shimano components cover this guarantee? Any input would be appreciated thanks Edited February 18, 2021 by markjamesmulholland@gmail.com Link to comment Share on other sites More sharing options...
DieselnDust Posted February 18, 2021 Share Dura ace and xtr carries a 3 Yr warranty globally.you'll have to work through your lbs and cool heat.Good luck Link to comment Share on other sites More sharing options...
Kooskoos Posted February 18, 2021 Share The bolt on my 11 speed XTR shifter on the handlebar also snapped off while unscrewing it. Luckily it had enough thread left to unscrew it using pliers. Surely this shouldn't happen to XTR parts and more than one person. Mark James 1 Link to comment Share on other sites More sharing options...
Christie Posted February 19, 2021 Share Was it torqued according to Shimano specification?If it is made from a lighter material like aluminium or titanium, the torque spec will be different compared to a steel screw. Link to comment Share on other sites More sharing options...

Surely this shouldn't happen to XTR parts and more than one person.XTR is race stuff. It isn't built as rugged and hardy as XT or SLX. The bolts are probably super light and if even slightly over torqued will fatigue and fail as opposed to a steel bolt 17 times as heavy with XT/SLX. Buying super light weight race stuff and using it as every day kit is living on the edge... In SA, 99% of the mechanics and especially home mechanics over tighten their bolts. Most people have their brake clamps so tight they dont move in a crash and I've seen carbon bars sheer as if cut on the brake clamp line. I've even seen a mechanic take a Hope seat clamp out the packaging, then proceed to torque it the point where the bold head snapped off. It 'shouldn't' happen, but it happens all the time.

I purchased the bike a few weeks ago, so I'm the 2nd owner, but I did loosen/adjust/tighten the shifters as they were too high for me. Yesterday, I tried loosening it, and the bolt snapped... Yes, I agree that it might have been over-torqued when previously tightened, but still surprised at how easily it just snapped off - Especially on top-shelf Shimano gear...

Mark James Posted February 19, 2021 Share So the moral of the story is I am now moody as hell, cannot ride, and need to take it into a shop to see if they can get the bolt out (fingers crossed!)

XTR = lightweight, probably titanium bolts which are soft. If they were over torqued, it weakens the bolt. The chances of getting a warranty for this, is next to none.

Surely this shouldn't happen to XTR parts and more than one person. It's a soft titanium bolt so it's probably galled. The bolts come with loctite which probably isn't appropriate as a titanium bolt in an aluminium thread should be prepared with anti galling compound. It should be a warranty issue but ya well no good luck. Let us know how it plays out Link to comment Share on other sites More sharing options...

Does the warranty from Shimano carry over to the second owner ( second hand bikes ) ? Eldron 1 Link to comment Share on other sites More sharing options...
David Marshall Posted February 19, 2021 Share Sounds like a quick fix with the right tools and a SS bolt. DieselnDust and AdamA 2 Link to comment Share on other sites More sharing options...

Mark James Posted February 19, 2021 Share I took the bike to Specialized in Stellenbosch this afternoon. The bolt was abso-fuckin-lutely stuck firm in the hole and they said the only option was to try drill it out, and told me there is only a 20% chance that they wouldn't damage the hole... The good news is that all ended well, and they did a great job removing it, and replacing it with another screw. Made the most of my time there, had 2 new tyres fitted, and now sitting with a cold beer plotting tomorrow morning's ride Edited February 19, 2021 by markjamesmulholland@gmail.com DieselnDust, ChrisF, Christie and 4 others 7 Link to comment Share on other sites More sharing options...
