I can;t get any tention on my chain I've got an onza t-bird frame and an onza sealed hub but my tugs can't pull my axles back very well, what tugs will work (not snail cams, no fitting for em atm ) So what tugs would work, or coudl i run c.k funn bolts and tighten them like bastards?, Or could i run a normal threaded axle with them?
