1" (one inch) headtube 1 1/8 forks Help please

[fireball_jones]

hi chris your are a man of refined taste indeed .

have you tried a sus fork on it? why is a high bb bad? i thought clearance would be improved?

i have been taking her on the trails but my hands have been hurting after a few hours of riding.

i havent tried a flexstem. i heard that they make you more likely to go over the handel bars due to the geometry change etc.

i think i would like to know my options.

i may try som fat DIY grips. but im open to suggestions

Hey fireball!

I poo-poo'd the idea of there being a 1" lock-out in existence on your old thread and I definitely stand corrected:

Bit pricey tho

I have successfully fitted a 1" fork into a 1 1/8" frame with some severe headset cup bodging... if you pull off this mod I will salute you!

Having the bottom bracket higher does mean more clearance, but it also means your centre of gravity is higher. Not good for stability.

If you are getting sore hands over a long ride, you might find altering your position helps. I'd start with a pair of bar ends, to give you have a couple of extra hand positions. Then, maybe some fatter tyres.

And of course make sure you keep your arms slightly bent while you ride. If they are locked solid, you will hurt yourself.

"Not good for stability. " not sure about that from my experience a bigger bike (taller) seams easier i.e balanceing a pencil and balancing a broom which one is easier?

i have tried so many things...bet arms, fat tyre at low pressure, sorry dont like bar ends though but do change hand p[ostions.

cheers. :roll:

Not sure if I agree with your analogy, it should be what's easier to balance on

I couldn't ride any, but I should imagine a waist height unicycle would be much easier than a 2M high one ... :?

That's a silly analogy.

A better one might be the weight of the rider balancing on the end of a pencil or the end of a broom.

actually the analogy comes from a friend who said it was easier for him to balland on a 6ft unicycle than a regualr one. but i dont know? :?

that does make sense ASWELL, but it still doesnt solve the orginal problem thanks anyway. the search continues.

I went to an mountainbike shop in Machynlleth with geezers old enough not to frown at a 1" steerer, in fact the owner had the marzocchi mx pro lo in his 1" mountainbike. sooo i thinking of getting it. As a student I'm on a real budget, but cant think of a better way of spending my student loan. however i may be eating alot of beans and pasta

any alternatives ideas? cheers

As a design student I assume you have access to engineering workshops? If so some ideas to throw into the mix:

1, get 1" and 1/18 headset. Cut inserts off both and weld/bond 1" inserts onto 1 1/8 cups

2, Get a steel headset, grind the cup inserts off then weld the cups to the headtube. Problem: high risk of irreversable catastrophe!

3, Machine a converter. 1" tube to fit your headtube expanding to a larger diameter above the headtube to fit your 1 1/8 headset. You can buy these for using 1" headsets in 1 1/8 steerers so the other way should be doable with some accurate machining. Problem: will extend headtube both top and bottom, throwing out frame geometry.

4) press out the steerer using a hydraulic Jack now insert a 1 1/8" - 1" shim and 1" steerer and press in with same jack.

I'd like some adive from those expereience tinkerer's/inventors who have managed to fit a 1 1/8 (threadless) fork into a 1 inch (threaded) headset.

from my investigation so far there is enough room for the tubes to fit inside each other its just the hardware e.g. headset etc

About 8 years ago Woodman Components had a headset that allowed for a 1 1/8” fork to fit into a 1” head tube. I’ve checked their site and it doesn’t seem to be available anymore. No I didn’t get it wrong or go mad I actually bookmarked the link on my old computer. Problem is my old computer has gone to heaven so I haven’t got the link anymore.

I’ll try and find the link with the WaybackMachine site.
