    Stem length???

    Any rules for stem length on a road bike? My hands are constantly getting numb and it's almost impossible for me to ride on the hoods for any length of time at all. So I'm assuming the stem is too long. The seat postion is fine, I've had the problem for a long time, my arms get so tired on longer rides it's getting very annoying. It's the stock one that came on the bike. On my MTB I went with a 90x5 Thompson that puts the bar centered on the front hub. Any rule similar to this when sizing for a road stem?
    Thanks!

    obscuring the hub behind the bars is just a starting point....fromt here to make adjustments.

    i've got from a 135mm to 110mm.

    see if you can slap a thomson on there (or something short with a face plate so you don't have to unwrap the bars) and ride down the street.

    riding the hoods should be slightly less comfortable than riding up on the bars.

    also, ask the shop if they have a stem that adjusts for sizing.

    Obscuring the front hub is a good general rule of thumb. As for pain in the hands and arms, that could be a number of things. Check your grip and how you have your weight distributed.

    Personally, I keep my stem about 1-2cm below my seat position, and when on the hoods, I don't see my front hub. As for my weight, I try and keep it distributed among the contact points on the bike: the pedals, seat, handlebar.

    I know what you're going through, so good luck finding the right combination. Also, you might want to try pushups 2-3 times a week. Just do two sets of ten. That can get the arms ready for the weight that's going to be on them for hours at a time.
