How to Replace Your Pedals

Hello there, I'm trying to clean my Shimano MF-HG20 freewheel, and want to disassemble the cogs. But I found there is a lock ring that seems need a special tool to remove it. Could you please teach me what the tool's name is? It is in 46mm diameter and has 8 notches on it. The notches are semicircle.   SHIMANO MF-HG20-1.jpg (Size: 81.38 KB / Downloads: 23) Thank you....

My 9 speed Campagnolo Mirage derailleur broke down & I am looking to replacing it. However, there aren’t any 9 speed Campagnolo (new or second hand) derailleurs available (in the Netherlands. (Well that statement is not fully true, I did find a second hand 9 speed Xenon derailleur, but I got it delivered broken) I can find a new Campagnolo Veloce 10 speed derailleur. Since I have seen 9 spe...

Bicycle repair newbie! I've been fighting and fussing with the v-brakes on my wife's bike. (The linear pull variety.) Watching lots of videos, but still can't get it right. Most likely the problem is my clumsiness and ignorance. Those two problems will likely be solved over time and I'm sure I'll eventually get those calipers adjusted correctly. However, if they actually need replacing, how ...

I'm fixing up my wife's old bike to sell and when I pulled the tube on the front tire it had water in it. Haven't seen that before. What would cause that and is it a problem I need to take care of? Thanks. John...

My bike brakes are unfortunately not working because when apply the brake the brakes press to the rim but my right brake pad does not spring back My Bike is a road master granite peak 26 inch wheels and my brakes are aftermarket and the brand is. “I know this might be a caliper issue but I don’t really know how to check that”...

Got this bike sight-unseen from an auction. Only recently found out there was a slight cut in the steerer after taking it apart. Around 1mm deep and is only on one half of the fork, it doesn't contact any of the headset bearings but it is within the headtube. Is this fork compromised? Or still rideable.   20210730_215646.jpg (Size: 22.41 KB / Downloads: 4)   20210730_2...

As you can see in the picture attached, my derailleur (Campagnolo Mirage 3x9) has a top bit broken off (The thingie that hold the spring in place, if anyone knows a nice name, let me know!). I cannot find any campagnolo mirage derailleur (second hand) online (in the Netherlands). So I have to questions in which I can need your help: 1) Is it possible to just replace that part of the derailleur? I...

It happens only when I’m pushing a big gear up a slight gradient in the saddle. My first thought was the BB needed to be replaced but I took it to the shop and they said it was fine. They thought they fixed the problem with adjusting the b limit but it only helped it maybe a little. It didn’t solve the issue. Would there be any other causes? I have Shimano GRX 810. Happens when the clutch is ...

Hello, cycling lovers! A couple of days ago I had a lesson of riding in a group, which ended with crashed bike =) Fell to the side, so the main impact was absorbed by my shoulder and hand, so I believe no major damage was caused by this crash except some paint removal. So I'm thinking about what to do with stripped carbon on the front fork - to me it seems that only paint is damaged and I'm thin...

Hi! After a holiday in Italy last year where I rented a vintage colnago with Campagnolo Atlantas, I was convinced that over the next year I was going to build up a Campag vintage bike of my own. Fast forward a year, I managed to build up a Giant Cadex with full campag 10sp with a set of Zondas. Last week I managed to pick up some Campagnolo Atlantas with Record Hubs and was thrilled. Then, I ...

Hi all, I'm aiming to remove this SunTour Cassette. Beyond a chain whip and wrench, it appears I need a special lockring. From my guesstimate, it seems like 'Cyclo 2 Peg Freewheel Remover' will do the job or some other of 2-notch lockring. I don't know how common these are at Bike shops and was hoping if anyone can offer some suggestions....

I had a minor collision with another cyclist. The bottom of the fork of the other cyclist’s aluminum frame hit the rear left side of my carbon frame and chipped it. I tapped around the frame with a penny and the sound is the same. Do I need to get this repaired?   5C9FA87C-F47E-404E-8CAB-A0213D6FBD24.jpeg (Size: 46.75 KB / Downloads: 25) ...

So as some who rides and maintains bikes from the 1960s to through the 2000s, I find disturbing that there are some many problems with modern shifting mechanisms on low to midrange bikes. I have an engineering background and it seems that basis quality in function and durability has gone by the wayside in this department. Is just a cost issue? I would be embarrassed as a manufacturer if I had the ...

Hey all, My CX/Gravel bike came with a Shimano GRX-810 (1x) drivetrain. The derailleur has a 34T max cog and, living in a flatter area, it's more than fine but I'm planning on getting in some climbing-heavy gravel rides later this year so was looking to get something that can take more teeth in the rear. A little digging around has identified the XTR-M9000GS, another 11-speed RD, as a viable opti...

Looking for ideas and opinions on this crack in my steerer tube. It seems pretty small and only on the outside surface, and the carbon is rather thick too. I have enough room to potentially slam the stem by cutting the area off, or I could try using a metal tube insert to brace the area. Or is it small enough to ignore for now? What do you think   20210723_211713.jpg (Size: 19.97 KB / ...
