How to Check for Chain Wear

I have a brand new 2020 Pake Rum Runner track frame (CrMo), which is supposed to have the standard 120mm rear spacing. It arrived with spacing closer to 100mm, and I can't get the rear wheel in. There is a dent on the inside of the drive side chain stay that causes the dropout to angle inward. I just bought a bunch of track parts from various sources for this specific bike, and I'd really prefer...

Here is an old Urich repair tool; patent date 1919. I picked it up merely as an oddity and had to research as to how it functioned. Essentially similar to the plug repair kit tools used for auto tires nowadays. Made for natural rubber tires, and using rubber bands with a vulcanizing agent. I assume it would still work with newer tires using the proper plug material and glue. I doubt it would be us...

It's making a light squeaking noise when I pedal. Not sure i want to take that apart, but maybe I should. It does not have excessive free play. it is NOT the pedals. It just started a few weeks ago, but maybe I could not hear it previously. This bike is OLD. 1950s or 60s. When I found it in 2013 it was laying in someone's backyard missing wheels and seat. Handle bars are slightly too low, but can...

Hi all, I'm new to the forums here, so sorry for any etiquette mistakes. I recently bought a new belt drive bike and after getting it built, I noticed that the frame split was quite rusty. I was told it was just surface rust and to just sand it and paint it with the provided touch up paint. I decided to get inside there and take a look and found the entire surface to be quite rusty. I sent pho...

I have bought Brooks B17 Imperial for my Fuji touring bike and would like to break in before taking it on a trip. Have read recommendations to reach 1000 km to make it fully fit. Right now it is winter in Norway, so I do cycle home using my road bike on Tacx trainer. Would it make sense for me to put B17 on my road bike and try to break in inside? Or is it bad idea since touring bike has likely di...

I am changing a 7 speed Schwinn to a single speed. It has a Falcon freewheel. I have the freewheel off of the bike and have removed the core by turning the Falcon ring clockwise. I want to also remove the cogs. There is a locking ring on the outside of the freewheel that needs to be removed. But I don't know if the locking ring turns counterclockwise or clockwise and what tools I need to rem...

Hey guys, I just wanted to point out the variance in the Stone Oval chainrings. They have two versions and they are particular to certain cranks. The BCD 96X is particular to Shimano M6000, M7000, M8000, M9000 M9020. The original BCD 96 is XTC820, M782, M612, M622, M672, M4000, M4050. Additionally, I have an FSA SL-K MODULAR 2X 392EVO MTB CRANKSET. The BCD 96X is not compatible with the spid...

My friend in Romania sent me some pictures of MAVIC Cosmic carbon rims/wheelset he is selling; only $160!!!   s-l1600 (20).jpg (Size: 99.78 KB / Downloads: 120) Best deal I've ever seen!

I need to replace the tires on my Specialized commuter bike- currently using 700x32; am I locked into tires of only this size? If not, what is the range of sizes I can choose from and still have them fit my rims?...

Hi I want to replace the fork on my dads schwinn meridian. I’m looking for one with suspension. What size is the fork I should buy? I been looking on internet for the fork size but couldn’t find anything. Thanks in advance...

I know someone who has a Schwinn Meridian adult tricycle. He said he has been unable to find much in the way of repair manuals or guidance for this model or trikes in general. I know some things are exactly the same as bicycles, but other things are different. He said all he could find was some assembly instructions. Just looking around on the forum I saw some info an pressing in new bearings and...

I'm going to replace the bearings in my Zipp 182 hub (rear wheel). Both the SRAM website and this article (https://www.slowtwitch.com/Tech/Hub_How-To_-_Zipp_182_3300.html) recommend against replacing the freehub body bearings, and that instead the whole freehub should just be replaced. I can only find one supplier and a replacement freehub costs more than I paid for the wheelset. The freehub bear...

Weird clicking sound. I dont think it affects performance but its really anoying. It doesnt only happen in the beginning of the stroke but also once it settles into sag and i compress it further i can still hear it. My question is what could be the cause of this and also, will it be an expensive repair ? Thanks Here is a video of the clicking sound: https://imgur.com/a/GWxkq04...

Hey guys, Recently bought a carbon bike that's quite old, noticed when I got it home this corrosion at the front deralliuer hanger. The frame itself is otherwise in great condition, including carbon forks which I have inspected. Is this a serious structural concern and should I be keeping this bike only on the indoor trainer? Thoughts?   IMG20211114131221.jpg (Size: 62.01 KB / Dow...

I'm looking for brifters that will be compatable with shimano grx 600 rear derailleur running shimano rd-rx812 11-42t 11 speed cassette that can operate mechanical disc brakes. I think the standard grx 600 brifters can only do hydraulic and I'm not keen to change the brakes. Perhaps 105 ST-5800 would do the job?...
