Re: [RBW] Headset adjustment

[Richard Rose]

Garth, thanks but not certain I understand. You say (I think) minimum insertion is “always to top of lock nut”. My minimum insertion mark is 2cm below top of lock nut. The quill goes quite a bit deeper to well below top of steer tube. I will remove to get an accurate measurement but it is quite long. If I read your response correctly you are thinking the entire stem is only 2cm below the top of the lock nut, which of course would be very bad.

The min insertion line on my stems on hand range from 6.5cm for a relatively short Nitto quill adapter to 7.5cm for taller Genetic brand one. My tall Nitto Faceplatter stem is about 7cm. 2 cm below the lock nut is quite insufficient, as in "Danger Danger Will Robinson !" That "may" explain the wiggle, not being in far enough. When it's in to at least the min insertion line there should not be any wiggle at all, as in zero. Stems shouldn't move when tightened, like seatposts. If your stem isn't tall enough, tell me exactly which one you have. I have an unused Nitto HighRiser, the original ones Riv had made in 135mm extension @10 degree up and a 31.8 clamp that I'll see you if you need it. 31.8 to 25.4 shims are common.Those high risers with the long quill and positive rise are as tall as you're gonna get out of a one piece stem. If that isn't high enough then the bike is too small ! Buy hey, if you ride a 59 I'll sell you my unused original orange Susie if you like as it has a much taller stack than any other RIv model. Too tall for me, I'd need a negative 75d stem.... hah hah . If the stem still wiggles when inserted to proper depth then the steering tube is out of spec. If that's the case, Riv will help you out !  FWIW, I bought a VO Rando frame that arrived yesterday and today got an email stating the rear recessed brake holes were made too small. So yeah, "stuff happens" even with "professionals". -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
