how best to deal with?

It’s (alu) in a welded on stop on the (alu) down tube. can’t get a std length drill bit in straight but may look for an extra long one. Then tap out.

Plusgas?

Would this kind of thing help?

A stumpy 90 degree drill adapter.

Leave it as it is and use an inline adjuster.

Mallet/Shards……etc…..

sstu…I’d love to but the head has snapped off.

A stud extractor should get that out no problem then.

Not where it is.

Not where it is.

Sirly there’s room to get an easyout in and turn it with a small spanner?

leave it ull be rate

maybe sstu…between it and the head tube?

full length outer and just ziptie the cable to the “stump”

Grind the easy out down and turn it with molegrips then.

Come on Al.
Use your mad construction skillz in a different way. 🙂

TBH I am thinking an M5 thread bolt with a 1.5mm hole, that’s say 1mm solid cheap aluminium, it needs drilled out, esp given how easily the head snapped off, an eazy out will just cut it up.

I bet the adjuster was already cracked before you tried to turn it though.

agreed.

How do you rate my chances re. comeback frmo ebay seller? TBF he’s already refunded me 15% for the scratched condition of the bike….

Had a similar thing on a road frame prepping it for powder coating – tried to take out the down tube barrel adjusters and they both snapped off. Did what you are suggesting – drilled out the stuck adjuster and thread in the boss and replaced with the barrel adjuster parts of this set:

All plastic (bar the retaining nut), been sound since, and should be no future issues.

Off course, I had the destinct advantage that I was re-coating the frame, so a few marks from the drill chuck trying to get the bit straight could be covered up after the event…..

Got a picture?

I’ve been there before…..

I used the tang of a small rat tail file…. heated up and bend the end of the file to a right angle(keep the end in a vice to avoid over heating it as you want it to keep its hardness)

hammer in gently …. turn gently..remove ……. repeat…

you could always try the same with a small torx key…

had the same problem got a shake drive for drill and used hexagonal shanked drills. I used several small drills and finished of with 4.8 the thread remaining just screwed out as the drill emerged out of the other side and i was able just to screw new adjuster in
