Nice looking bike - still too damn small for me.

I hate the way modern bikes have massively-long seat posts.

Its better for mountain biking .

why?

so you can have the seat lower ?

well, you've got a more useful dropper, your nads are safer as well

and you have more freedom of movement forward and backward of the saddle

yeah - I've bent 4 seat posts which were at extreme extension, and I've broken one frame at the seat clamp for the same.

so, long lever arms seem like a bad idea to me

"long-leverage"

@Criggie - did they have enough insertion?

Yes, but at the limit.

Still I was 100 kilos back then

so a lot of mass and leverage

weird - cleaning up a pile of bike junk and there's a 4x frame in there

a raleigh MTB frame with 4 chainrings

No rear wheel and no shifter so I can't see how many rear it had

quad chainrings - 26 tooth small and 48 tooth large

weird

any markings?

one of these? abundantadventures.com/quads.html

Nah its got 2 teeth more on the big cassette than my road triple, so its not really that big. Just got two chainrings in the middle rather than one

Maybe it's like shark's teeth. As one set of teeth wears out another grows to replace it.

@Criggie I've read that too, but it doesn't tell me anything.

Based on that I'd say its a 1 and 1/8 of an inch and is not tapered. It is threadless though.

Its not impossible I'm wrong. Consider emailing the manufacturer? Or go look at one in a LBS ?

The picture shows a straight head tube, not the conical ones seen on some bikes. However that could be hiding more on the inside, so take the picture with salt.

hm. i just realized i can buy a fancy bike once i start working.

@Criggie I have the bicycle, although not right now, it's at the repair shop. The head tube looks a bit conic.

just ask the shop when you pick it up

@CristianCiupitu, @Criggie, it's a straight 1 1/8" headset. If you look at a bike on with a tapered headtube it says clearly in the specs.

It is hourglassed between races, no idea why, for lookin' fancy's my guess
