This is my bike. My rear hub is making a bit of noise and doesn't feel very smooth, so I think it's a good idea to overhaul it. Just to confirm that this is what I need: Freewheel remover (This will work right? My freewheel is a Shimano MF-TZ06) (Also is this better or worse than using a...

After 7000 or so miles on the original equipment, the non drive side hub cone on my rear hub was pitted. It was pretty severe, so I pulled everything apart and checked the race (?) inside the hub and it was not damaged, just the cone. I replaced it with a Wheels Mfg. cone, replaced the...

I understand what makes Front and rear caliper brakes different. Whats the difference between front and rear Cantilever Brakes?

Hi, all - I've been rebuilding and repairing a garbage-picked Huffy English 3-speed. Project bike. The rear hub is a Shimano, not the classic SA. It's been baptism by fire - learning how to do it as I go. Right now, I'm working on the chain. My problem is trying to figure out the length...

I recently returned from a trip to Colorado Springs where I attended the Barnett Bicycle Institute. I was there for three weeks and took four classes. They were the bicycle assembly and maintenance class, the repair and overhaul class, along with the effective sales of service, and management of...

I have a set of Shimano 600 brake levers I am giving to a friend. Her hands are quite small and unfortunately there is no reach adjuster screw on these levers. I seem to remember some...wedges that can be used to hold the lever in a slightly closed position. For the life of me I cannot seem to...

I recently installed a SRAM Omnium crankset using the stock bottom bracket. Everything seems to be fine visually. I made sure to torque it to the correct settings using a torque wrench. I greased all of the threads as instructed by the manual however I neglected to grease the bearings themselves...

I may have touch(ed) my chainwheel regularly with my right shoes, in the period before using SPD. The black coating has been scraped off a bit here and there. How can I touch this up - not like to spray paint though...

Would there be interest in a bike repair wiki? Some website where the whole community contributes to create excellent articles for everything from simple bicycle maintenance to the more complex stuff? I thought about creating one a while back, but don't want to create just another bike repair...

Hi All, There are lots of threads on this topic and I've read quite a few of them. But would like to pose a few more specific questions. First of all, I have a 2008 Specialized Allez triple. It originally came with Sora Front (triple) and Tiagra 9sp rear. It has the Sora shifters and Tektro...

I'm planning to replace the cassette on my Cannondale H300 hybrid. The current one is 11-28 and that is what I'm used to. If I replaced it with a 12-32 cassette would I notice a big difference? Also, I'm looking at the Shimano HG-70 (11-28) and the SRAM PG-730 (12-32) cassettes. Is one better...

I know there is a company which takes bike chains once you fill up a box full of them, and they recycle them or make jewelery or something. They pay for shipping if you have a full box. I figured the mechanics would know the company i was talking about.

I took my bike in to have the drive chain replaced and they said they would put on brakes for a nominal fee. Since then, the day after it rains my brakes squeak and I do not know why. Anyone know why this is and what I can do to stop it? Thanks! Jim

Hi guys - anyone know if a freehub that fits a 10-speed 105 cassette will also fit a 10-speed SRAM Rival cassette? AFAIK, they are fully compatible, but someone told me there is a difference between a 10speed-only Shimano hub and a 9-10 speed compatible Shimano hub, and only the latter is...

I posted this problem earlier today, but somehow it disappeared. Does anyone have a problem with their silca not letting go of a presta valve after you've inflated a tire? I've actually pulled stems off because it's on there so tight. Any help would be appreciated.

One of my Shimano PD-6610 Ultegra SPD-SL Pedals sticks and does not spin well. I checked the tech doc link below - and it says take it to a mechanic for help with moving part issues! Can anyone tell me how to take it apart so I can see what going on inside the bearings? Hopefully it just needs...
