Threaded conversion to Threadless - Ghetto?

[skinnyboy]

So my mate brings over his old Mongoose Sycamore which needs some TLC, manage to spruce it up but the fork steerer's threads have seen better days on the Rock Shox Quadras.

I tried adding a some thread locker and a new top nut but it keeps working its way loose.

Since its 1" its nigh on impossible to get some decent forks for it and the steerer is a non changeable design. This got me thinking. What if I replace the headset with a threadless one, replace the stem with a clamp on one and use a 1" quill adaptor.. is this a fail waiting to happen?

Yes, a big fail waiting to happen. Do it on your own bike but not on somebody else's, not someone you like...

The quadras have probably seen better days anyway, spend the money on rigids.

I've lowered a quill stem all the way down to stop headsets coming loose before.

I am going the way of a threaded headset to aheadset design via an adaptor, as to me, I have weighed up the pros and cons and arrived at the fact that given my style of riding and engineering mentality, the idea is ok. More parts to move if ridden hard, but with more parts the pre use checks are more thorough.

Would a headlock help ?

que?

The bike in question will never be ridden hard just a pub bike basically, I reckon i might weld the steerer to the head nut haha

Headlock ;

There were some others on the bay recently, some Tange BMX locks, but they appear to have gone, but I have one of the old Grey's Industries head locks.

But a head lock is a ring that screws on above the headset and locks via the use of a bolt to cinch the ring in place.

You're joking, aren't you? How are you going to preload this? If you get more than 5m down the road without the whole set up rocking and destroying the bearings I'd be surprised.

If you use a quill to ahead adaptor and 1'1/8th inch ahead stem you can still pre-load it. I'm sure I've got an adaptor somewhere that you can screw an ahead cap into to pre-load it instead of a star nut. I did a search for adaptors and there are plenty out there, plus shims to use a 1'1/8th ahead stem with a 1 inch aheadset. If they are being sold to adapt 1 inch quill to 1'1/8th ahead they must have a way of pre-loading the aheadset. Will have a rummage to find mine. From memory mine is 1'1/8th quill to 1'1/8th ahead.
