    Sram s100

    I'm looking to upgrade the stock POS crank that came on my bike but probably can't afford a sweet omnium crank.

    Has anyone tried the S100?

    The S-100 is essentially the same crank as the Truvativ Touro (with a slightly different look) that comes stock on the Kilo TT. It's a decent entry level crankset.

    I have it, crank is decent, the bottom bracket is where my issues lie. the first one went to **** like 4 months after the install. Replaced it and the new one has been flawless since. The bb is also a lil on the heavy side too. If I could go back I'd go S300 for a lighter and probably more reliable bb design.

    What are you not liking about your current crank?
    What crank is it?
    Are you able to spend more than the $80 you can get an S100 for?

    Cranks are pretty much cranks. As long as the length is ok, the chainline isn't jacked, and there's nothing defective about your stock crankset, you aren't going to see a significant improvement going from one cheap crank to another. Stick with what you've got until you can affort something substantially better.

    What would be considered a good start for an upgrade?

    S100s are nice cranks. Some people have BB issues, but I've had mine a couple years with no problem. They are better than sugino messengers, IMO.

    My current crank is a no name, Made in China special. It just doesn't feel solid, and the bottom bracket sounds and feels horrible also.

    I would spend more than $80 if there was a good reason to. I mainly want something that feels solid and will last. My current set up is far from it.

    The more money I can save, the more parts I can upgrade.

    Buy nice or buy twice. Save a little more and get a substantial upgrade if the cranks really bother you. I use the S300s, and am highly satisfied with them.

    I liked my S300's too. If I were building a bike and wanted black cranks that weren't higher end, I'd go with them.

    If the crank doesn't spin smoothly, then you need a new bottom bracket, not a new crank.

    As for not feeling solid...how do you know it has anything to do with your cranks? What you could be describing could be related to a loose cog, poorly tensioned chain, poorly tensioned spokes, a flexy frame, flexy fork, among other things. Crank flex is generally minor compared to other areas in a bicycle that flex.

    Furthermore, cheap cranks are cheap because they have a cruder finish and are made of more material, and are thus heavier than expensive cranks. You aren't likely to add stiffness by buying a lighter crankset.

    Cheep steel frames can flex in the bottom bracket area under load, and cheap chain rings will feel, for a lack of a better word, sloppy. Those two are much more likely to be your issue. Chainring is something that is an easy upgrade, that will feel much better right away. And if you combine that with a new BB you will feel great.

    +1 on the S300's. I got them for around $86 new just through a little googling.

    Thanks. I think the main issue is probably the BB. Any recommendations for a good BB?

    The bottom bracket is the biggest problem. I would like a decent crank to to go with a new BB, and am searching for one at a good price point.

    As in solid, I am speaking more to the quality than the flex. They seem very cheap. By cheap I mean they feel brittle compared to higher quality cranks.

    The bike is about a month old. I started noticing problems around the crank/BB area about a week after I got it. Everything else feels fine elsewhere on the bike.

    Assuming you have JIS tapered cranks.

    since it is only a month old...why haven't you already taken your bike back to where you bought it & have them check any problems?

    btw...what kind of bike?

    For those saying "save up and buy once" "wait and buy a better model and not an entry level"...What would you suggest then? We have already heard about the 300, but besides that model what do others suggest besides the regular omniums that everybody has?

    Andel and their many rebrandings would be a good choice. IRD makes a nice affordable crank as well. Miche is on the higher end of the price bracket but also a nice crankset.
