How to Adjust V-Brakes

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...

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 ...

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...

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 / ...

Hey, I got a giant trooper, with the gear ( Sram Twist Grip Rotary Handle DualDrive ) and cable broken and not working, do you guys know if its hard to change it myself? I live in amsterdam and in a shop is too expensive to replace the gears. Any thoughts about this? Where i can buy those type of gears? it is possible to change only the gears part that got the numbers? When i change gears on ge...

So my front derailleur shifter is not going in 3 Everytime I push it for a slight moment the chain stands on the 3rd gear.And when I stop pushing it goes back to 2.The last pic is when I pushed the shifter to 3.And the shifter is very hard to push   IMG_20210724_201313.jpg (Size: 63.04 KB / Downloads: 22)   IMG_20210724_201418.jpg (Size: 64.34 KB / Downloads: 24)  ...

Purchased this last week and went to pull the crank off today. What I found is that the threaded hollow on the non-drive side is too shallow to fit both the bullet and the threaded extractor nut. With the improvisation, I was still able to remove the non-drive by using a small, thick washer. Certainly not recommended though. I believe I saw Shimano makes their own crank puller for Octalink, so tha...

Hi, I am trying to pack my bike for travel and cannot get my pedals off. I know that the left side pedal is reverse threaded etc so am pretty sure I am trying to loosen them the correct way on each side. But both pedals are stuck fast and I dare not force it in case I crack the crank. Any good way of loosening pedals which are screwed on too tight?...

Hi, Pardon me if this is not the right place to post the below question. My bicycle gear was not shifting properly so I decided to fix it after watching several youtube videos. Several videos advised that the gear should be shifted to the highest speed (i.e. smallest cog) before doing any tuning i.e. adjusting the High/Low limit screws or adjusting the cable adjustment barrel of the derailleur. ...

So, before I explain the issue, a bit of background. I took my bike to college, but ended up not riding it much, so it sat outside for the majority of the academic year, chained to a bike rack. Because of that, many of the screws and gears and such have rust on them (I know, I'm an idiot for leaving it outside and probably ruined it, but I'm trying to fix what I can). The bike is still ride-able ...

Hello there, I have been trying to remove the cranks from an old bicycle frame. I use a crank puller (with an attached arm) according to the tutorial on this site—turning the external threading clockwise into the crank, then turning the inner bolt of the puller equally clockwise against the spindle inside the crank in order to force it off. Nevertheless, the crank will stick in place. I have tr...

Just wondering about the possibility of upgrading only the front brake of an Apex 1 mechanical grupo to hydraulic. I figure the front brake does way more and it would save a ton of $$. What I'm wondering about is if the left hydraulic brake lever/hood would have a different shape compared to the mechanical brake right shifter. Anyone know exactly how different they are and if it would f...

Hi, everyone, My 6¾-year-old son was due for a new bike. Without consulting, his grandfather bought him one from a box store. My son loves it. Honestly, it's mostly an OK bike from what I can tell (with all the caveats about serviceability, etc., that come with a cheap bike). However, the brakes are dangerously bad. From running speed, the stopping distance is on the order of 40 feet (12 m) (my ...
