Dave Sutton Posted May 27, 2012 Report Share Posted May 27, 2012 Hello, i recently broke my rear hub and i need a new hub/wheel the last hub i had had a 126mm axle and the only 20" hubs i can find have 116 the size of my frame on the inside is 117 so a 116 wouldnt fit at all as i have to put the bolts, lock bolts and snail cams on, what can i do! I have a Neon Conquer 20" frame Quote Link to comment Share on other sites More sharing options...
Martin Reynolds Posted May 27, 2012 Report Share Posted May 27, 2012 A 116mm hub will fit your frame. Just because your frame is 1mm bigger, it'll bend in when you do your axle bolts up. Quote Link to comment Share on other sites More sharing options...
Dave Sutton Posted May 27, 2012 Author Report Share Posted May 27, 2012 Yeah but the 116 is measured from the inside of the frame thats 1mm holding on when jumping off walls, doesnt seeem rightthe 117* Quote Link to comment Share on other sites More sharing options...
Martin Reynolds Posted May 27, 2012 Report Share Posted May 27, 2012 Sorry not entirely sure what you mean. Guessing you have snail cams for chain tensioning? Then you'll need a 110mm hub like http://www.tartybikes.co.uk/116mm_fixed_hubs/onza_tmaster_sealed_rear_hub/c62p102.html the extra 6mm is taken up by the snail cams. You dont have to worry about the extra 1mm, when you do the axle bolts up, it'll pull the frame into the hub. Quote Link to comment Share on other sites More sharing options...
Dave Sutton Posted May 27, 2012 Author Report Share Posted May 27, 2012 Why was the axle that was last on my bike 126mm? Quote Link to comment Share on other sites More sharing options...
Revolver Posted May 28, 2012 Report Share Posted May 28, 2012 (edited) You are mixing up measurements. On a mod hub the actual axle is longer than 116mm. Remember that it sticks out into the dropouts. 116 is the spacing. That's the gap between the dropouts on the frame, and the distance between the axle spacers, the bits on there too wide to go into the dropouts. In your other thread your bike bends in because you have a 110mm spacing hub, you just need to pad out the spacing with washers or snail cams. It's not broke because of that so don't buy a new hub if that's the only problem. I might add that the measurement of the actual axle is mostly irrelevant and shouldn't be an issue.
