OK, I confess. I stopped by the local Harbor Freight tonight and shelled out my $12 for a little 1000 gram scale to weigh parts on. See, I'm putting the DH bike on a diet for this season, with the goal of losing a couple or three pounds (or more) if I can do it without breaking the bank. Bonus points if it comes off unsprung weight.
My plan is to: lace lighter rims on my hubs and try butted (gasp!) spokes; replacing my inverted fork with a right-side-up model; swapping out my Stroker Ace 4-pots for the new Primes; trying a 2.35 tire on the rear (plan to keep my 2.5 Excavator up front doing the important work); shopping Ti springs for the RC4; and putting my minimalist Sunline saddle back on.
So then I get this added stroke of genius - - the cassette. But of course! My PG970 DH (11-26), with its two solid big cogs, is a pig: tips the scales at 322.8g; my new PG 950 11-26 is a svelt 223.5g. I know there are super-weenie road cassettes like Ultegras and such that are even less but gawd this was a cheap fix. What the hell is wrong with me? This weight-saving thing is turning into a sickness.
