    Shop Advice: Toronto Area (Stripped Stem Bolt)

    Hey,

    I just picked up a new bike that unfortunately has a stripped stem bolt.. I tried knocking a larger size imperial key into the bolt to get it out with no luck . So now it looks like I need to find an expert who can reverse tap it our use a dremel to make a slot for a flathead. Also, i'm slightly afraid that the wedge might be stuck, which might be why it was stripped in the first place.

    Any shop recommendations within the GTA (Downtown would be best) with this type of experience would be greatly appreciated!

    Thanks!

    Well, first the obvious answer, if it's a new bike, the shop that sold it to you should look after it.
    If that is not an option, for whatever reason, if it's worth a Go train ticket out to Clarkson, I could meet you at the station, (but not until next Thursday or Friday,) and probably fix you up right in the parking lot, no charge. I have extraction tools specially made for removing stripped hex heads.

    Hey Dan, thanks for the offer. My worry is that the wedge is also stuck. Do you have experience getting these out as well? It's an older Ryffranck bike that I bought used and the head didn't appear to be that stripped on purchase.

    Are you talking about a quill-type stem, here?

    If so, they can usually be tapped out from below with a suitably thin rod or stick of some kind.

    When you say 'new', do you just mean 'new to you', because if you don't then the place you bought it from should sort that out if it was a pre-existing defect, surely?

    Oh yeah, dealt with lots of stuck wedges. They almost always yield to a hammer blow on the bolt once it's loosened.
    I though from your OP it was a new bike, I guess just new to you, huh?
