    newbie questions

    hello all. another big guy who wants to ride a bike. i'm 5'10" 350# and for now i'm only interested in riding around my neighborhood streets for fun. i went to a trek store and a trek 4300 was recommended with a frame size of 18". durability was a concern of mine because of the weight and this one was mentioned because of the double walled rims. i rode it in the parking lot and it felt ok. i didn't really know how it was supposed to feel since i haven't been on a bike in most of my adult life.

    i started watching craigslist and found a 4300 with a 17.5" frame for $150. i went yesterday and checked it out. the bike was in storage and the tires were deflated so i could not ride it. i noticed right away that one of the suspension lockout knobs was missing and the fork had rust on it. i said this was probably not going to work for me and the seller lowered to $100. i ended up settling on $80 and took it home. i figured i would at least get a good idea of what i want in a bike after i spend some time with this one. if after some time i ended up disliking the 4300 i wouldn't be out so much money.

    i took the bike home in the backseat of my car so i had to take the front wheel off. i ran into a snag when trying to close the brake mechanism. i aired up the tire first, then the brakes wouldn't close. it seemed i had to let air back out of the tire first to clear the brakes. and really i can't remember the order in which i did this but think i did it wrong the first time.

    anyways, i got out and rode down the street. wow, that felt great! i rode faster than i thought i could. that brings me to another concern: the front and rear brakes are pretty noisy. being inexperienced, i don't know if this is normal or not. the pads are making good contact with the rim but it takes a little too long to slow down, and if i apply enough force i think it's maybe louder than it's supposed to be.

    after that quick first ride i made a seat height adjustment and rode around the block trying out the different gears. at some point as i was pedaling it felt like maybe the chain was slipping? i was pedaling hard. then it would all lock up and i could not pedal. that happened a few times. one theory is that because the seat was causing me a lot of discomfort, i was putting more of my weight on the pedals.

    i'm going to take it somewhere to get it checked out but i would appreciate any insight. overall the bike feels like a good fit and i would like to put on a new rigid fork and whatever else needs to be done to make it rideable for my purposes. new saddle...road tires?

    Welcome to the Forums -- and glad to hear that riding is fun for you!

    It would help us figure out what's going on if you could post pictures of your bike. I'd like to see the brake pads, the chain rings, and the derailleurs, for starters. Does the chain feel like it's slipping all the time, only when you're changing gears, or when you're staying in the same gear and pushing hard (ex: standing on the pedals to go uphill)?

    A common reason that brakes get noisy is that they sometimes lay exactly flat along the rims. If they're angled slightly, so the pads start contacting with just part of their area and then contact more territory as you pull the lever harder, they get quieter.

    Wish I could help you more than to direct to www.sheldonbrown.com Start with this section http://sheldonbrown.com/beginners/index.html and from there you can start branching out to his more specific articles on bike mechanics.

    A lot of people advise to start out with a Craigslist bike so I did the same thing. I believe that starting with a Craigslist bike will do at least 3 things.
    1. You will learn to become a bike mechanic because you will have to fix things more than you ride unless you learn #2 first.
    2. You will become a semi-expert at appraising bicycles before you buy from Craigslist or you will follow item #1.
    3. You will learn to appreciate your LBS (Local Bike Store) and buy your first bike from them and thus skip steps #1 and #2.

    I thought I started at step #2 but step #2 only happened after step #1 became a necessity. Today I am jumping to step #3 so that I can actually ride a bicycle while I improve at steps #1 and #2 because a true cyclists will be adept at steps #1 and #2. Maybe that is why so many advise starting at Craigslist?

    Hopefully Sheldon "The Guru" Brown's advice will get you over the hump.

    thanks for the reply, here are some pics. the slipping seemed to begin after i was pushing hard but from that point in continued like that all the time. i will check out the angle of the pads. if i remember correctly, i think these are not the stock brakes.

    i did intend on purchasing the 4300 from my lbs and in hindsight i probably should have, but this was a very spontaneous move and i'm stuck with it for now.

    The Chain needs cleaning and oiling. Small front sprocket and small rear sprocket at the same time is to avoided. Examine brake pads for small stones embeded in the pads. Get some chain oil into the cable housings. You can do this by getting some slack in the cables and unhooking them from the frame. Then slide them back to reveal cable and oil cable. Be sure you understand how their routed (pictures). Rust never sleeps.

    Its a used bike that was in storage so you might need to do some minor repairs/adjustments.

    One possibility is that the brake pads just need to be towed in. Most online tutorials can help you with that. Another possibility is that the pads have aged and become hard and just need to be replaced. Usually not that expensive depending on the pads.

    Your chain locking up can be from a couple of factors. My first advice would be to check the cables and deraileurs to make sure they are shifting properly. It could be just a quick adjustment on your deraileurs or you just need to replace the cable and housing.

    The problems you described don't sound like much. While it is always a good idea to learn how to do basic maintenance/repairs yourself, you can always bring it to your LBS for a once over.

    Good luck and enjoy riding .

    Hey, it is a pretty good deal. If you find that you want to ride more than you expected you can upgrade and not be out near as much as you would have with a new bike. And it is good to learn how things work. I just bought my niece a cheap craigslist bike and we are going to learn how to maintain it together.

    It is usually possible to get the wheel on with the tire inflated. Some brake levers on the handlebars have a mechanism to release tension on the cables. Sometims you can take the cable housing out at the bridge, below the seat or above the fork, to release the brakes. In your case, I would guess that you can pull the end of the cable housing out of the caliper near the wheel to release the tension.

    Just don't forget to re-tension before you take off, or you could be in for a surprise down the road!
