How to Calculate Chain Length

Please watch the attached video. I gave a ride to person on my luggage carrier and her jeans got stuck in the chain. Ever since then, my back has been making this "ticking" sound or whatever you can call it, and it feels as if there's a bit of resistant to the pedals and a "locking" motion sometimes. Moreover, the wheel seems to be swinging a bit in the video and it's not turning in a straight cir...

I am upgrading an 8 year old Scott Solace from the Ultegra 6700 series, have acquired almost all the new components but wondering about the shifters. I have the Shimano Ultegra ST-6703 shifters for a triple. They work on my double crankset with a 10 speed drivetrain. What I am trying to find out is will the 10 speed shifters work with an 11 speed setup? Like I said, the shifters, even though they ...

Hi guys, I have restored a 90' Fisher mountain bike. It works perfectly apart from the front derailleur. Gears goes down no problem. They go up from the first to second cog no problem but it is very difficult to make it go to the biggest gear. This is an old SRAM groupset. It is not the cable tension, not the limit screws and not the position of the derailleur on the frame. These are the basic t...

First time adjusting a headset and I'd like to get it right. Brand new giant reign with a carbon frame, that I do not want to damage I finally have the preload set to where there is no play but I'm concerned that it is to tight... Stage 1- obvious play/clunk Stage 2- no clunk, but if I lock up the brake and push and pull hard, I can feel some very slight movement Stage 3 - no play or movemen...

Help please! I have tried many things to fix the loud clunking sound in my Meridian trike with no success. We even took the gear hub apart and reassembled it per the suggestion from Schwinn that it probably needed replacing. Many others have suggested something in the rear axle tube is making the noise, but I don't understand the descriptions. Are there videos to watch on this matter? Or is there...

Hi all, my rear deraileur got caught in my chain and got pretty mangled. This is my first time replacing a deraileur, and I've found a few good guides on how to replace the part, but how do I actually choose a replacement that's compatible with my bike? Here's some images of my bike (an old Ross) for context: https://imgur.com/a/wNYqQkH Would either of these deraileurs work? And how do I know if ...

Preamble A sad week for me, as I have been attempting to convert a 2017 GT Transeo 5.0 (in Gunmetal) into a road trainer bike for two years now. I've had so much trouble finding a rigid fork to cover the distance lost from the suspension fork (one that also includes disc mounts—and doesn't make the build look vulgar). I've gone through like 3 or 4 carbon forks, including an ENVE RD, all which w...

I have a bike which i was given and I've found the Sram MRX grip shift will change gears on my front deraillier but the numbers on the shift don't correspond to the gear the bike is in.In other words when shift is on one the small cog is selected.When I select the middle cog the shift hasn't got to two yet.Its only on about one and a half.And when the big cog is selected the shift is only then on ...

Hey guys, see the video link below.

I recently bought a second hand Fit Bike Co frame and purchased a Rant headset to go with it. The integrated bevels for the headset bearings are too shallow for the bearings that came with the Rant headset. Is there smaller sealed bearings that will sit flush in the head tube?   9A475497-E514-40B4-AF32-8435D21C77E1.jpeg (Size: 45.52 KB / Downloads: 9)   9900865D-5E1C-48...

Hi all, there is lateral play as shown in the video and I’m not sure if it is just the freehub or the wheel bearings too? The hub is a cx22 which came with Cannondale Synapse 2019 and I’m not sure what parts are compatible with the hub. Any ideas what would work or am I (actually it’s my sister’s bike) in new wheel territory? Thank you in advance.   7A3A3C6B-D716-4CDC-AB...

Hi! I’m new here and I have a GRX810 groupset. I am trying to bleed oil from my rear hydraulic brakes and I got the oil to drain from the calliper hydraulic bleed screw. Now I am trying to push new oil back from the bleed port but I am not able to, the syringe is not moving at all no matter how hard I push. So I have checked the following: calliper is not blocked, oil can flow from bleed sc...

I'm a former racer attempting to build a business selling bike bleed kits, and I am in this class where we are working on a product/service feasibility assignment. If you're a biker or have some knowledge in the cycling industry, could help me out in taking this quick survey for a business idea of selling bleed kits for bikes, motorcycles, and other vehicles? It involves looking over a one-page ...

I bought a can of mineral oil from motorex and it came in 250ml aluminium can with big cap, and I need to fill my brake lever with that oil but I don't have syringe or bleed kit. How could I fill it up without syringe or bleed kit and tips? Anything similar to syringe that would work?   54e2f371.jpg (Size: 152.52 KB / Downloads: 88) ...
