Many thanks for all the reply’s from the community ,sorry if I’ve not responded personally to them all ,caustic soda method it is then ,I’ll do an update when done ,I fully understand the process now ,never realised quite how much material is physically removed , and also health dangers ,I didn’t go the chemical route because it was hard to believe anything would be better than than trying to shift the expander than bashing a steel bolt screwed in with a mini sledgehammer once the fork was free of the frame but just ended up with a bent bolt and dropouts stuck into a big block of wood

Thanks ,I’ve tried everything mechanical including getting a much longer bolt [before cutting] to bash expander down to no avail ,looking up from below I can see the conical expander has been pulled right into the stem ,i’am struggling to find a long [20+cm’s]metal drill bit at a reasonable price ,I’ll try chemicals next,one of my students has been gifted a single speed bike but both post and stem were stuck ,got post free’d and hoped stem would follow ,thanks

Any recommendations as to a shop to drill out the remnants of a stuck quill stem please ? I’ve obviously tried everything and now trimmed stem to top of steerer ,done so fork is now free and easier to transport but also so at worst I can move on with putting in a new fork etc but owner would still prefer to keep original fork if possible ,scoured the archives but so many shops have changed recently,many thanks in advance ,Stef

Don’t seem able to add into original description,will include some basic pedals with plastic toe clips and if needed a used once Tortec Velocity alloy rack + new ‘P’clips[frame hasn’t rack braze ons at seatstays],think this rack is based on the Tubus Fly+ a new unridden rear wheel ,a Suntour GRX hub and wide cog set [both NOS]laced to a new Son rim 36 hole,built up by Brixton cycles

There’s been no incentive for manufacturers to push limits of quills since ahead became the standard ,in general new quill fitted bikes have been absolute bottom of the range or the very top custom made where owners are maybe more concerned with stem reliability and less so saving weight ,maybe some of the lightweight quill stems used different density alloy [?]certainly that SR looks v slim with little widening out at stressed areas ,struggling to find weights but you need to Google the stems fitted to original René Herse bikes which were also made in-house and I think the new owners are re-introducing them ,if an original ever comes up for sale it’ll be around £500 ,but they are absolutely stripped back

If someone has a yearning for a retro Vitus style bonded alloy build the build /bonding quality on these was great ,a real step up as was the vitus 992
