Stripped the hole where the rear rack connects to the frame! help!

[aNOMalous]

So I finally received my super sexy rear racks for my lady and I. I put mine on my bike with no problems but I stripped the hole on the frame where the rack connects near the seat post. Is there any way to fix this?


Any tips or info would be appreciated!!!

I am assuming you don't have the tools to re thread it in a slightly larger size , you could try some PTFE wrapped around the bolt , that's the white plumbers tape . Or a slightly larger bolt eased in and see if that grips enough of the old thread , or a nut and bolt with a couple of washers .
Best of luck .

Yes it is fixable - the proper way to do it is with a thread insert called a helicoil - not normally a DIY job though. An internet search should find you a local engineering workshop that can do it - many garages can too I suggest. They are used on many stripped thread applications.

drill it out to next size up and re-thread it. set of taps are cheaper than hellicoil kit - but there needs to be enough meat there to go up a size and for the hole in the rack.

another option - if and only if there's enough clearance behind it without it fouljng the hub - use a nut and bolt - easiest if the bolt goes through from the back

Did I miss the bit where the OP told us what his frame is made of? Did he tell us if it's a threaded hole into the tube or a brazed/welded on boss? Is it the upper or lower eyelet? It's not possible to give the right answer without this info. And maybe a picture.

Use P clips

On the trikes
I always drill them out to 6mm and fit 6mm NYLOC nuts and high tensile bolts , they stand a better chance of not breaking or coming undone .
Stainless Steel cap bolts of marine quality ( some have a shallow but wider head ) look nice and dont rust .
Kays of ebay is a good source and deliver in 2 days

I've used both of these options. My LBS did the rethreading for me - about a 10-minute job for them.

Second what @mickle said though, we're making assumptions here without having seen your bike.

I did exactly the same to one of mine.

A slightly longer allen bolt and a nyloc nut has kept it solid for years.
