I’m not obsessed but any way I can sensibly (Cost effectively) reduce the weight I’m lugging about I’ll consider.
There are actually some quite cheap ways to keep the weight of a bike down too, not all cheaper stems/seatposts/bars weigh a ton, it’ simply that people only tend ot look at the weight figures on pricier kit ignoring the details of the “Cheap tat”…
Plus there’s also the weight penaly for having all the bells and whistles fitted;
-3×10 Drives may be the newest thing but I bet you could have a lighter 1 or 2 x 9 setup for much less that would give plenty of usable ratios…
-uppy/downey posts (although I quite like the idea) do generally come with a weight penalty.
-Bigger brake rotors than you perhaps need, simply add more mass…
But those are all things to consider after you get the overall layout of the bike right, handling before weight loss in my opinion, the lightest bike in the world may barely bother the scales, but if it rides like a Mare and beats you up then it’s not worth having IMO…
Put another way – does anyone think I will be better off taking my 30lbs Prince Albert rather than my 22lbs Rocky Mountain for a solo Mayhem ride this year? Not worth obsessing over but certainly worth keeping an eye on when spec’ing a build – first suss forks I ever had were 2.2kg and no better or stronger than the 1.7/1.6kg Revs & Rebas I ride now.
Ignore the weights, which one is more comfortable to ride for long periods?
Take em both out for a good long all day ride and see which one leaves you feeling more beaten up at the end…
