Sean can you please post some pics of your situation im not familiar with this set up. :cornut:
Wasnt knocking in fact impressed, love seeing the old Mags still in action. :thumbsup:seanmankiw said:Don't even want to talk about the components on the bike for that picture. I took my racing parts off when I had it at college.
So what have you done, stripped out the hex in the top of the bolt? You should be able to screw an easy-out into the bolt and back it out that way. Sears has a Craftsman 10 Pc. Screw Extractor Set with a couple different sizes that are probably appropriate to your problem. Never the less, it is no reason to have a melt down and a fairly simple problem to resolve. Good luck!seanmankiw said:I stripped out the very poorly thought out bolts that hold my Mary's ebb in place. The threads on the frame are fine, the bolt is 1) stripped 2) seized.
What's the internal diameter of the BB? According to Niner you need a 55mm internal diameter for their new ebb to fit. It looks like a couple people have had good luck with sanding the inside of their bb shell or sanding the Niner ebb itself if the bb shell is just off.downhilljill said:I have to agree with Momentum...the long bolt you have sticking out of your BB shell might cause damage to your frame.
We had very few if any issues with the EBB set screws on the Mary. I keep mine clean with the little grease on them and it's all good. That area picks up a lot of crud on any bike. It's a good idea to remove the bolts every now and then, clean them, grease them, and re-install. You can also blue loctite them if you are inclined to do so, but just make sure you still remove the set screws and clean them up from time to time to prevent seizure.
We don't have any experience with the Niner Biocentric system to comment on whether or not it would work on a Mary frame. It looks like a a cool system. Maybe you can post your thoughts on it if you choose to install one on your bike.
