Hi all
I am super keen to get rid of my sloppy suspension fork and stick in a rigid. My suspension setup is a 11/8 non threaded steerer. Now I have a 700c fork in my possession but it is a 1’ threaded. The steerer length is fine. Is it achievable to sleeve the 1’’ steerer and throw in a star nut so I can use the threaded fork an ultimately my existing stem and hangers. If so is there a kit available for such a task? If not do you want to sell me your old 700c 11/8 unthreaded rigid fork ?
Cheers Bikehack
Can I fit a 1” threaded fork to a 11/8 unthreaded head tube

What State/City/Town/Suburb do you reside in? (A note to all - it helps if you include your location in your profile).
If you are requiring a threadless 1 1/8" 700C fork, what is the minimum length steerer you require? I assume it'll also need brake bosses on it (for v/linear/canti-type brakes). If you are replacing a suspension fork, you may find a rigid fork may be a bit shorter which may affect your bikes handling.
Cheers

Hi kukamunga thanks for the reply I have updated my profile with some extra info. My current setup is running 2 and half spacers so the steerer length is about 200 - 220mm. Yes I agree with the geometry issue you raise. I have read a bit on it and the majority of users that have done it suggest it is an not a major issue for their bikes performance / handling. I was looking at a 29†fork (surly karate monkey) that suggests it is suspension “compromised†. This being said the fork is for a wheel that is 8mm bigger than a 700c. Does this make a difference? And yes I do need brake bosses. It becomes expensive if you need to buy race brakes and the clamp on thingy to mount them
cheers
cheers

Check your 'axle to crown' height on your current suspension forks, and take maybe 10mm off this measurement (for sag). The 'Karate Monkey' is 468mm, and the 'Cross-Check' fork is 400mm for comparison. I may have a CrMo 700C fork (with canti-pivots) that may fall somewhere in between those 'axle-crown' measurements
'Axle to crown' measurement is from the centre of the axle to the bottom of the steerer/ top of fork crown (where the bottom face of the lower headset bearing race sits)

Just checked my only 1 1/8" 700C fork, and it only has a 150mm long threaded steerer . BTW, the axle-crown measurement is 410mm, and it's a 4130 CrMo fork off a Shogun. I'll keep my eyes peeled for later model, larger framed Shogun 'hybrids' on my hard waste runs in the next few weeks.
Has anyone tried using a threaded headset and stem on a longer threaded steerer? Would the combination of a clamp-on threadless stem onto a threaded section of steerer be a combination for potential disaster ie. shearing/ cracking of thread potential?
If a long enough threaded steerer could be found, the thread can always be cut off. I'll check in Abbotsford Cycles this Saturday. They have a box of second-hand forks - might be something there.....
