C-40, what's your method? Can you explain it?C-40 said:I have a method for lengthening a steerer by up to 1.5cm. As a mechanical engineer, I know it's perfectly safe and actually stronger than the original setup, but the mere mention of this possibility always brings doubtful comments. I've been riding a LOOK KG 461 with a steering tube extension for several years with no problem.
No, that only works with threaded headsets/1" threaded steerers.olli said:you could maybe get something like this

I think you could try flipping the stem. I can't really tell from the picture, but it looks to me like it's in the -8° position. (Again, I could be wrong - I really can't tell from the picture...)Streamwood Steve said:The stem is a Deda Newton 120mm. According to some web investigation the angle is 82.
C-40 said:I can e-mail some details, but in a nut shell, you need something to provide M6 threads for the top cap bolt, then fill the entire stem clamp area with an epoxy like JB Weld. A very ordinary copper tube coupling has the perfect 1-1/8" ID to be used as a form to allow the epoxy to extend above the steering tube. To provide the necessary threads, I used a 1" star nut, with the OD filed down slightly, so it slid into the steering tube without interference. I placed a small piece of foam rubber in the steerer to keep the epoxy from running down below the fill area.
