GB Spearpoint Barrel Adjuster 1965 Raleigh Carlton

Just picked up a small Raleigh Carlton frame for cheap. It came with the original GB Stem and handlebars but the stem is missing the barrel adjuster. Anyone have a good source for one of these? Iíd like an adjuster for the rear brake bridge as well.




Interesting lugs.

Plenty of patina, faded paint, and paint scrapes; still, no dents and the missing decals are replaceable. With proper care this can still be a nice looking frame.

Chrome is not smooth but still looks nice enough if you donít look too hard.

I think S = 1965.

I doubt that's as manufactured, in which case there is no "correct", most likely any adjuster you like that fits will do.

Nice score.

I seem to kind of remember ( I'm old) that the adjusters in the Simplex delrin downtube shifters fit the brake bridge and if it is the same might also fit your GB Spearpoint.
The above statement might be totally incorrect and I have no way of checking (sorry) and I am slightly hesitant to post but hey.......if you have any of delrin shifters hanging around it might be worth a try.

Thanks for the replies. I should be more specific. On 1960s bikes Carlton often employed this stem with the brake cable routing going right through the middle. This is as manufactured. The hole is threaded and the bolt required for the stem is considerably wider than the rear adjuster. I do appreciate the responses though.

Thanks Big Block. A workaround is probably what Iím looking at as a placeholder until the real deal shows up.

I would think the stem takes a standard barrel adjuster as found on a brake caliper. Have any of those around to try?

nlerner for the win! This adjuster came straight out of an early 80s Weinmann side pull caliper. It wonít be the one that I use but clearly this was easier than I thought it would be. Thanks nlerner.

A perfect fit.

Reawakening this thread in hopes of some insights from the Carlton crowd. Pcampeau , did you end up sorting an adjuster for the rear brake bridge? The Catalina I recently picked up to bring back to life has the same bridge and I don't have the Simplex delrin downtube shifters mentioned by OTS . No original stem for me, and my replacement Nitto doesn't rout through the stem, but I'd love to know what others have used in the rear. Any leads much appreciated! Thanks!

surprising good fortune that Weinmann thread compatible with Gerry Burgess stem

would expect Burgess products to be all fractional and the Weinmann (or Diacompe) barrel would be metric

another problem solved by the collective forum savvy!

I can confirm that the Simplex part as seen on some 60's-70's downtube shifters will work for the rear bridge.
I can also state from memory that the stem adjuster is larger, originally of plated steel with a plated steel jam nut with a knurled edge. Never bothered to measure the thread pitch, but as it is British...
My hunch is SAE and or Metric won't work especially well. I would look to UK ebay and or an old UK bike shop.

Further digging in the search function points to this thread: Q: rear brake barrel adjuster (or cable stop) for Raleigh/Carlton frame in which the OP ends up using a step down ferrule, which seems like it might be a decent workaround, though obviously compromising on adjustability.

Awhile back someone sent me this link on the Show us your Raleigh Super Course thread when I was wondering about getting a brake bridge adjuster for my 68 Super Course.

Unfortunately mine is a screenshot and not a link. Sorry Iím a technology dinosaur and I just donít know how else to do it.

I have not built the Raleigh Carlton as itís too small for me, instead Iíve gifted it to my brother.

I'm guessing the correct one for the rear brake bridge would be the 5mm, non-threaded "with spring and eared sleeve" (shown on the right-hand side)? I think the active link is: DiaCompe / Weinmann Centerpull Brake Hardware at Yellow Jersey
