    Sirrus Comp

    I just got a sirrus comp, and the weight is right at 23 lbs. Would like to get it down to 20. Has anyone done this and what would you recommend, thanks

    What size tires is it running? Is it a stock spec new bike or...? More info would get you better answers but generally smaller tires or lighter wheels is a good place to start...

    going to thinner tires would save about 60 gr total, which is .13 lb

    A lighter wheelset, say about 1500 gr.... should shave about a 1 lb (assuming that the DT Axis 1.0 is 2000 gr).

    If you went to a say a SRAM PG1050 11-32 (instead of 11-36T PG1030), that's a minimum of 100 gr savings (.22 lbs).

    Carbon bar would give you around a min of 80 gr savings (.17)

    A road saddle, maybe if your sitbones are 143mm.... that's another 100 gr. savings (.22 lb)

    A carbon stem... maybe 50 gr (.11 lb)....
    ... that's about 1.85 lbs and a lot more money.

    maybe carbon seatpost... maybe it would give you another 65 gr... which puts you close to 2.0 lbs savings.... and even more money spent.

    Best ROI is to get lighter wheels. You'll notice weight differences in rotating parts, the further out, the more you notice. This means a weight reduction in tires, tubes and rims matter most.

    However, lighter wheels may be less durable. Not to mention the out of pocket expense. Good luck!
