    Bike struggles to move (ok, I struggle to move anymore) ??

    I had my crank system(ultegra 9 speed) switched with a compact crank system. Didn't like it so switched back. I noticed things seemed a bit tougher. My race speeds dropped for the same race.

    And over time pedaling has gotten tougher it seems. I have to go slow(HR 135) vs a normal 150. Is it possible the mechanic cranked down to hard on the sealed bottom bracket cartridge.
    I also noticed the ball bearing in the wheels are extremely crunchy now and sometime they catch a bit on the rotation of the wheel.

    Not sure what is going on? Went out today and did 44 miles and it felt like I did 100 miles or more. My swimming and running speeds have all improved. I am training to do my seconds Ironman later this year.

    thanks

    Sounds like the wheel bearings could be bad and the crank bearing could be bad or the preload set too high.

    BUT those would not affect your HR. Just your speed. You could need a rest.

    Your wheel bearings may just be too tight. Adjust the cones (assuming not sealed bearings)
    What type of hubs do you have? How old?

    You may also need to clean and repack the wheel bearings, again assuming loose ball bearing hubs.

    I'm not sure you can mess up the sealed cartridge bearings like you're thinking, but they wear out over time.

    If both your speed and HR are going down, then perhaps it is also related to your riding style and motivation.

    Riding the compact crank probably made you a weaker cyclist, and now you'll have to build your strength back to effectively use a standard crank again.
    Too old to ride plastic
