Hobgoblin torque spec question.
I just purchased the Hob and love this bike, love it! I have questions regarding the torque specs that are listed on AB website. They list the various specs below.
Upper and lower shock pins: 100kg/mm
Upper Pivot to frame (6802 bearing): 200kg/mm
Upper Pivot to seat stay (699Z bearing): 90kg/mm
Lower Pivot to frame (6802 bearing): 200kg/mm
Lower Pivot to chain stay (6902 bearing): 180kg/mm
These seem very high. If you convert it to lbs/in it is 11,199.48 and 1265 nm again all way out of range for a bicycle. I thought it was a typo and contacted AB for some explanation. In the mean time what do you all think? My feeling is it should be expressed in kgf/cm which would make it a respectable 19.6 nm, using the 200kg/mm as an example. Your thoughts? Thank you.
Bringing this thread out of retirement... I have had these specifications stored away for a while - I got them from the Airborne site a while back. They seem really low to me, so I emailed support@airborne tonight to see what they recommend.
Upper and lower shock pins: 0.98NM 8.67in/lb
Upper Pivot to frame (6802 bearing): 1.96NM 17.35in/lb
Upper Pivot to seat stay (699Z bearing): 0.88NM 7.79in/lb
Lower Pivot to frame (6802 bearing): 1.96NM 17.35in/lb
Lower Pivot to chain stay (6902 bearing): 1.76NM 15.58in/lb
Mine has developed play in the upper pivot where it is attached to the frame - almost as though the "tube" on the frame where the pin goes through is worn - at the top of the suspension travel there is a noticeable knock, and play in the suspension, which is causing creaking.
Hopefully I'll have an answer on the torque settings soon, and I'll update the thread - this was about the only thing that came up in a google search, so it might help someone else in future
Answer from Airborne Support
Just for future reference, if someone searches for Airborne HobGoblin suspension torque specifications in the future - here's the response from Airborne support:
Upper and lower shock pins: 09.8NM
Upper Pivot to frame (6802 bearing): 19.6NM
Upper Pivot to seat stay (699Z bearing): 08.8NM
Lower Pivot to frame (6802 bearing): 19.6NM
Lower Pivot to chain stay (6902 bearing): 17.6NM
USE Loctite 243 ON THREADS
Seems the website had the decimal point in the wrong place - I can't find the page any more, but apparently it's been corrected.
