How to Adjust a Threadless Headset

Hi All, These are my current rims: Wheeltech TD26 by Alex Rims (can't find much info about these online). I need to replace the rear wheel as it is cracked (cracks on the rims around a few spokes) It's a 700C disc brake rim with quick releases. What do I need to consider other than the size of the wheel when choosing a replacement? I'll likely migrate over the cassette and rotor (if need be). ...

I have a 10-year old Trek 7.3 FX with approximately 7,000 miles that is in need of a lot of repairs. I recently went to a repair shop and the mechanic thought the repairs would add up to the price of a new bike. It's true that almost everything but the frame and handle bar need to be replaced. It's also true that a large part of the repair cost comes down to the mechanic's labor. I am comfortabl...

Hi All, I'm new to owning and maintaining my own bike and have been having an issue with my bike that is about 2 months old. More or less, I am stuck in the highest gear on my bike (7). I physically can't crank the twist handlebar shifter down. Did some research and troubleshooting, I physically "shifted" the derailleur itself left with my hand and was able to get the bike to shift into a lower...

Hi, new here. Do not know much about maintenance, that is why I need an advice on chains. I have KMC chain on my hybrid and someone told me that I can use a bit of WD40 to keep it running, clean it from dust and whatsoever. He also is not very bright in terms of bike knowledge so I am doubting his claim. Probably WD40 is not good for lubing the chain or keeping it clean, right? There is need for s...

I just received this chain tool by post. Could someone tell me what the hook is for and why the handle can move down a little bit and pull on this hook? Thanks   tool.jpg (Size: 82.7 KB / Downloads: 31) ...

I don't know much about bike repair, and I'm a cheapskate. I currently have two different non-usable 26" coaster brake cruisers. One, the Schwinn, has a good front wheel but the coaster brake no longer brakes. Considering the cost of the repair vs. the bike, not going to repair it. The other is a 26" La Jolla that has a bad front wheel (bearings, I think). I propose to switch out the good front ...

Would there be any issues with one less tooth on the high gear as regards shifting or otherwise?...

I can adjust it so that I can change from the middle ring to the small ring or middle ring to the large ring, but not so that I can change between all three. The high and low limit screws are not restricting movement of the deraileur. This only seems to be a problem since I replaced the middle ring with an oval one. If I squeezed the rails of the derailleur closer together would it help. Seems li...

First, some context. I have two bikes, a 29" mountain bike (that I bought off craigslist and repaired) and a 26" cruiser bike (that I have had for about seven years now). I am 6'4" and the 29" bike fits me better, so I use it a lot more. That bike is in currently in need of repairs (the front crankset is bent, which I have no idea how that happened) and I decided to use the cruiser bike until I ...

I am currently repairing an old Miyata road bike and I am in the process of removing the rust from it. 99% of the rust has come off without difficulty (it is looking pretty good at this point) but I noticed that some of the rust has eaten through the chrome. Is there a way to reapply chrome to a bike? If so, how would I go about doing that? Thanks in advance....

Hi. I picked up a used older trek 3500 to convert to an ebike. I thought it had holes to mount disc brakes in the back, but when I went to put on the adapter, I found that it didn't fit. The holes are only 45 mm apart instead of the is standard 51 mm. Are these an older version before it was standardized to 51 mm? Something else? If they are an older version of disc mounts, anyone know where i can...

Hi guys, have been surfing through the forum for repair tips and answers in the past, but never posted. Good, useful information here My 29" MTB has bent rear disc brake rotor, is Shimano 160 milimeters. It's a very slight bent, yet it really annoyz me during training rides (I'm getting ready for my very first 100km+ marathon, still a novice) and is touching the brake pads, makes bad sounds. Any ...

Don't know if I have missed a discussion on this, but I have been looking at the frames made in China and most of the reviews have been good. A carbon frame and fork for $300 seems too good to be true. Does anyone know anything about the various frames on e-bay of different values ($300 - 500) and what is different about each of them. They all come in carbon black - does anyone have ...
