Another R20 Riser Question

Hello All,
I want to keep the fork and headset original on my R20 but change handlebars. Can I drop a 22.2mm (7/8") quill riser such as either the Soma Quill riser or Nitto Technomic long stem into my R20 and just use the existing clamp without the quill to tighten, or am I missing something? Thanks.

I suppose so, I did the same in my bicyle, not with a stem, but a inverted seatpost that I used as a stem.

Inside the standard R20 stem there is an arrow-shaped slot ground into the stem as well as a strange wire contraption that somehow helps to keep it all together when you tighten the quick-release clamp. (It's a while since I dismantled mine )

You can definitely fit any 1" quill type stem in the headset but I don't think you can also take advantage of the clamp and turn the bars 90° on the fly when you want a quick fold. I may be mistaken but I'm pretty sure the bespoke nature of the Raleigh stem is entirely to do with this 90° swivel fold and don't think normal quills will work the same way.

Huw,

That strange wire thingo connects to the brake bolt that goes through the fork, so the head stem can't be pulled too far or completely out.

I'm thinking that as long as the diameter of the replacement riser is the same as what is in there now the clamp would work and I wouldn't need to use the wedge. Does this make sense?

Yes, that makes sense. I put a quill riser in my R20 and just used the clamp instead of the tightening the wedge. I worried, however, that cranking on the QR clamp might not be good for the riser, since it was designed to work with the wedge. It may be fine, but I'm back to using the wedge.

You shouldn't have any problems without the "wedge" as it will stay tight as the original.....I've used the inverted seat post method and a quill type and had no problems with either.

The wire thingy problem is easily fixed with a simple wire cutter. That's how I took care of mine.
