How to Calculate Chain Length

I suppose I should wait until daylight to do the job. My new lever shifter came a couple of days ago and tonight the handlebars arrived. Maybe I'll just remove the brake levers, twist shifter, grips, computer and light and then get some sleep. Well, it's stripped down. Maybe I'll just put the bars on and then get to bed. Yes, they look good but they'd look better if I just put the new lever shift...

Hello bike riders! Newbie here, happy to join. Visited fam during the holidays. Found my old Fuji mountain bike in the attic. Took it back home to use for weekend rides and occasional commuting. It has rigid fork. I prefer to swap it for suspension fork. I want it to be a DIY project. My first bike build in other words. Might get overwhelming at start. So where do I begin? Anyone here has done rig...

I ruined my expensive dynamo powered front headlamp. This is the kind that adjusts to motion and knows what time of day it is as well as having a built in ability to charge my phone and other electronics. I was ecstatic when I hooked it all up and went out on my first night ride with it through Forest Park in Portland, OR with four other buddies. I was over the moon in the early morning commutes t...

Hello, bike riders! Our community member Gabriel has shared his unpleasant experience with Deore T610 brake levers: "After 2 years of very limited use ... I'm still trying to understand why is there so many holes in such a critical place" Can anyone help by explaining the reasoning for such lever design and what might be the cause of the particular break (material quality, usage, design flaw)? ...

I have just acquired a Cervelo Soloist 2006, has the Ultegra 6600 groupset. It was making a clickity grinding sound whenever I'm on the larger 2 or 3 sprockets (doesn't matter which chainring) when I'm pedalling hard and fast. Anyways, took my crank, chain rings, and bottom bracket off to clean, inspect, regrease and retorque. Greased my new pedals and torqued them on. Adjusted my front derailleu...

Hi, I posted this on reddit and got the suggestion to come to the experts here instead so here I am I recently had my front wheel of my vintage Bianchi stolen. First I was looking to just replace the front wheel but since the rear wheel is pretty old as well I'm thinking I might just change them both and at the same time size up from 23mm to 25mm for a little extra confort Does anyone have an...

Hello, My apologies for the simpleness of this question. I have a 1995 Gary Fisher Hoo Koo E Koo that I need to replace the front axle on. How do I find what to buy to replace it? It is missing so I cannot look at the existing part for guidance. Thanks!...

I have a brand new MTB and the rear disc break is already rubbing/squeaking. What are the easiest fixes? Thanks...

I have a 2018 diamondback line 27.5” . I rode it a few times and the crankset makes a popping noise as i pedal most likely due to being 230lbs. Any recommendations on what i could replace the old ones with that would work better with my weight and handle my riding better....

Hey everybody, New to world of cycling, recently my bike started to not shift as smoothly as it was before so I thought I would check to see if the cable was frayed. I detached the RD cable and inspected it, found no issues relubed it and re attached the cable. Since I have done this, my shifter will only click 7 times, and I have a 9 speed so it should click 8. I’ll walk you through what I d...

Back disc break on my Orbea commuter got much weaker this week. Front break is strong as always. I dont think that smth special happened, like crash, that damaged the brake. Never worked much on disc brakes. I want to fix this myself but I dont know where to look first and dont want to mess smth up. Where should I start? I have Shimano mech disc brakes....

A couple of years ago I bought a new front derailleur from my LBS. He said it will work for a triple chain ring. I didn't install it right away, and in the meanwhile I stopped dealing with him because of numerous botch jobs. When I put the derailleur on the bike, it won't work on a triple chain ring. I can make it work on the small and middle ring, or the middle and large ring. So I'm stuck with ...

Disclaimer: I am not a professional bicycle mechanic! After reading many procedures/methods for chain cleaning, utilizing many solvents/lubricants and/or water; I have only found one method that actually does the job properly and effectively. I am not here to "poo-poo" other means of accomplishing this goal, just providing what I have found has worked for me without fail. First: "wiping off" a...

What (if there is any) is the difference between 9, 10, 11 speed rear derailleurs?...
