I took your guys advice from a couple of weeks ago and I put a 90mm thomson stem on the blue and grey monocog. The raceface prodigy stem was 80mm and scary flexxy. I also got a awnser protaper 2" riser to replace my 1.5" hellbent riser, and lose even more weight.
I rode the combo today and it is much much stiffer then the prodigy stem with the titec bar, even standing and mashing up a short steep hill, no squeeks, or groans. Nice position also. I figure I lost about 4-5 oz with the swap over. About 30-40 grams from the stem and probably 100g from the bar.
Thanks for the good advice, one of the best performance upgrades I could have made.
