some decent ideas there, Thanks.
To answer a few questions..
I Don’t want to demo an Alfine equipped bike, I’ve had a short ride on one alrady and liked it enough as a gear system. I seriously doubt anywhere would have a bike to my taste with an Alfine to demo anyway.
I ride a dirtjump hardtail as an all round bike (All round to me means everything from long XC rides to DH & DJing to pissing around in the woods).
I did ride my hardtail single speed for a while and loved the silence, confidence and directness of having no gears but unfortunately it lost all it’s versatility as an all rounder.
My Hardtail weighs 30.5lb and is already at the point I couldn’t really get away with fitting anything lighter to it without durability issues.
An extra 600g I could live with, but not if it’s detrimental to the handling having all that extra weight rotating at the furthest rearward point.
Hopefully you can see why I really want to have extra weight fixed to the hub and not the frame.
What I think I might try is home made Playdough in a tube wrapped round the hub body and gaffer taped (and maybe a ziptie for good measure). this way I should even be able to get it balanced by simpy squeezing it while in place to distribute the weight if needed to keep it spinning as usual.
I make playdough for kids all the time anyway so it’s really not a hastle at all and won’t really cost anything more than the price of some flour and salt.
might try this over the october break as I’ll have time to go jumping/DHing and XC riding then.
