Aluminium dog bones /out drives

[ayske1]

Hi all

Running on high traction carpet shorty lw chassis and last weighed just over 1800gm. Probably less now with indoor tyres.

But I'll be running a 100c shorty that will increase the weight to maybe another 80gm.

I was wondering do the aluminum centre dog bones,alu out drives help much? Are they a bit overkill?

Also is it the 68/76mm ones I want for the bmax 4 iii ?

Thanks!
