Anyone using spacers on their hub?

TheBrick Have you tried moving the chain ring to the outside of the spider (if it isn't already)? This may bring you close to 45 mm and with a asymetric cog (a brand was mensioned in another thread) and or spacers this may be able to sort you out? Just an idea.

This is my next try. On the inner side of the spider (nearest the centre of frame) is the chainring, then on the other side of the spider is a metal bash guard.

I think I might be able to take off the bash guard, measure the thickness where it bolts to the spider, then order some spacers of the equivalent thickness from hubjub, then space the spacers between the spider, and the chainring on the outside of the spider.

Mr Smith - you have a goldtec track rear do you not? Could you measure what the chainline line is please i.e. from the inside of the drop out to the where the threads end?

i did a little sketch in photoshop just in case i'm making little sense (the red bit)

goldtec say the chainline is "roughly" 45mm. im hoping i can use a thiner cog, and then space the chainring - and all should be well (within a couple of mm)

ta :)
