- Extending a steerer tube any ideas?
The tidiest and lightest solution I’ve seen was a piece of oak that had been lathed down to the steerer outer diameter, with about 2 inch at one end that was lathed down to just slightly larger than the inner diameter. It was then hammered in to the top of the steerer, the compressive forces holding it in place.Posted 4 years agoalbinoMember
What Simon said. 🙄
Don’t think I’d trust it for any more than canal paths though!Posted 4 years agotrebordMember
Steerer tube extenders which clamp on to existing steerer are a standard bit of kit widely available. However, they’re not neat looking.. I have one on my hack/commute but wouldn’t think to place on a decent build. That would be a case of changing forks or even just steerer (costly) or opting for a lower stack stem and headset.Posted 4 years agomick_rSubscriber
I wouldn’t weld to it as you have no idea what grade the material is (esp if an aluminium steerer). Some of the steerer extenders work ok (the ones that go in like an old quill stem) especially if at least one clamp bolt of the stem goes on the original steerer (so stem bridges the join).
Have a look at different stem designs – some use much less clamp length.
Also, how much head tube sticks out on the frame (if a conventional not integrated headset)? I’ve cut and then re-faced frames before (but mostly old hack frames not new ones).
e.g. if you are 20mm too short, then you can gain 10 mm on a different stem and cut and re-face 5 mm from top and bottom of HT = 20mm recovered (just be careful fork top caps clear the down tube before doing any cutting).Posted 4 years ago
