How to Replace a Wheel Rim

How can I tell whether my rims are worn to the extent that they're liable to split from tyre pressure? They've had about 7000 miles of travel but the wear depth is probably 1/4 mm. It could be more, but since the pads have worn all over the width of the rim, there's no unworn section to compare it to. I could measure the thickness with a micrometer....

Am thinking of buying a new bike and was wondering if anyone could tell me if the wheel,that I use on my trainer would fit on the new bike. The wheel in question is an XRIMS y2000 622x20 6061-T6. It has a Shimano CS H631-8 Cassette on it. I use it on an 08 Trek 7200. I am thinking about buying a Fuji Absolute 1.9 and am wondering if this wheel will fit as is....

Hey everyone, new here, and also new to riding bikes. After 29 years, I finally learned to ride and after a month of riding, this morning my tire messed up. I'm still not sure what happened (and forgive me for not knowing the proper names of specific parts) Here's a picture of the damage, hopefully someone can explain to me what happened and how it can be fixed? Much appreciation. If this is s...

Hi there, I have an old Shimano FH-1055 hub which I have dismounted it and now I cannot figure out the order of reassembly for the spacers/cones/washers (I know, stupid me that I have not take care in the first place) The biggest issue is on the cassette side where I have 4 or 5 separate pieces. Not sure if relevant but note that the cassete is 7 speed and has no dirt seal (like I saw on other ...

Hi everyone, Recently I had some trouble with my freehub. As my local bikes shops are reluctant to fix my bike, because of being a b'twin (it's my work bike), I tried fixing the problem myself. Now, servicing my freehub and bearings wasn't much of a problem. En passent I also installed a fresh cassette and chain. Plenty of information on that online. The problems are now in trying to reinstall ...

I have 2 fairly new, mid-range folders which ride quite well d seem like good bikes for the cost. 8 sp. Shimano components. I have a 7 second video of this. When I was recently cleaning-lubing the drivetrain, one of them was wheels-up and I did the customary pedal-spin the rear wheel and when it the wheel slows down to a near stop, it reverses direction for a small fraction of a rotation, then s...

I have an unusual question I'm hoping to get answered on this forum. I've got a fixed gear bike that I want to convert to a horse training device. How do I get the rear wheel to become free wheeling, so I can turn it backwards as well as forwards? It has a bendix brake on it. Do I need to remove that, and if so, is there a special way to tighten the chain and hub? I'm kind of grasping here, s...

I own a Trek District SSB, which uses Trek's proprietary belt drive system. I'd wanted a bike with an internal gear hub, but they only offered a 3-speed version as an upgrade, so I decided to buy the SSB and upgrade it myself to something a little beefier. The SSB has the same frame as the IGH 3, so it already has the cable guides for the hub. I'm going to take my bike to a local community shop t...

I bought an old bicycle and see an unusual metal part attached on rear axle. Derailleur side. Starting from end I see a closed (no hole) bolt, two washers, then this "handle", a washer, then a deep nut, then a washer, then the derailleur, and then the bike frame. "Handle" is about one inch across and three inches deep, quite thick metal...flat but one edge has a perpendicular flange about 3/8 i...

I think the rearing bearings are 13mm ID and 30mm OD. Are these measurements correct? Please help. Thanks....

I have a 10 year old Trek 7200 Hybrid. I am thinking of replacing the wheels in a while and was wondering what you guys could recommend. It came with Matrix 750's but they are no longer available. I tip the scales around 230lbs. and am looking to spend around $300. any suggestions....

I won a Specialized Daily in a contest. It is a pretty sweet bike. But it has an internal gearhub on the rear wheel. I have never had this type of gear setup before. I am afraid to mess with it to get the wheel off. How the heck do I remove this wheel to change my flat tube? Thank you in advance for any assistance. ...

Hi. I have a fairly cheepish bike, Appolo Evade Mountain Bike. (The reason for it having a freewheel was probably due to price not age). Anyways. So, there is a tiny bit of freewheel wobble which I have come across on a lot of freewheel bikes so I never considered this a problem. Freewheels just tend to get a little bent right? Despite this, shifting is just fine and smooth and the whole drive ...

I recently bought a second hand Giant Upland SE and to be frank, it is my first bike with multiple gears. The bike functioned normally for the first day or two. I could shift between all the gears. When the bike is stored indoors, the pedal and wheel work fine but once I take it out in the cold (anywhere from -10 to -30 degrees celsius), the pedals rotate freely and have no action on the wheel. Al...
