Re: How to make YouTube cycling videos?

I came across Da Vinci Resolve, which I've been playing with. But it seems really fussy with file formats/codecs, so I'll definitely have a look at Blender, Shotcut and Lightworks when I get a chance.

Cheers :D

How to make YouTube cycling videos?

I've seen videos on YouTube showing a cyclist's front and rear camera feeds at the same time (side-by-side, or with the rear video in a little box, etc.). I'd like to make a similar kind of video (for fun). But I'm not sure where to begin... :-/ Can anyone suggest any simple video-editing tools to d...

Same here -- not an issue. My cheapo cams don't have any clever "image stabilisation", but the images are decent enough. There's no obvious vibration issues when riding on tarmac.

Re: Advice For Buying A Cycle Cam

PM sorry to read this and I hope your ok but is a camera really the answer ! I just find it strange that a car suddenly pulled out on you . Really how can that happen ! I'm surprised any road user would question whether that can happen! People do crazy things. I saw a woman stop her car to give way...

Re: Replacement SRAM X9 jockey wheels...?

Thanks, all. I found what I needed.

I came across a copy of the 2018 SRAM Spare Parts List on the SJS Cycles website, which made it easy to see which models were made to identify which one I have.

Replacement SRAM X9 jockey wheels...?

I've trashed my drivetrain and had to replace the chain, cassette and chain rings. With everything so worn, I presume it would be a good idea to replace the jockey wheels on my SRAM X9 mech too? I've been looking for replacements, but I'm so confused by the different options. I seem to remember that...

Re: New chain skipping

Today I fitted my new cassette, replaced my rear mech with an old working spare, and even with the OLD chain, it worked! No skipping at all! :D I put the original rear mech on, and it still worked. I compared the two rear mechs and couldn't see or feel any differences or faults. So, it must be the c...

Re: New chain skipping

Does the chain sag when the bike is stationary? If when freewheeling may be sticky freehub - the sag would be more pronounced on the smaller sprockets when coasting. I had a sticky freehub last year, which I cleaned and re-greased, so I know (from experience of what it feels like) that it's not tha...

Re: New chain skipping

Check for binding and/or poor spring tension in the jockey cage pivot of the rear derailleur. The pivot could have stiffened up with corrosion (SRAM mechs are more prone to this). The pivot moves really smoothly, and the tension seems okay -- hard to tell. But a spring/tension failure there would t...

Re: Derailleur hanger, B-screw, chain tension...?

I noticed that the B-screw had worn away part of the tab on the hanger it was supposed to press against. I replaced the hanger with one that was slightly bent, but had an intact tab, and the B-screw still only made partial contact with it... As for the B-tension screw not making proper contact with...

Re: New chain skipping

…..This slackness means it's not pulled firmly against the jockey wheels and cassette gears, causing it to "bounce over" the teeth of the cassette when force is applied..... if the sprockets are slightly worn then they will be slightly hook-shaped, and under load the rollers will 'climb' ...

Re: New chain skipping

The fact that it is the smallest sprockets associated with the skipping suggests to me that they may be worn even it is not obvious, the small ones tend to wear out sooner than the big ones on my bikes therefore I would also try a brand new cassette just to see if that fixes the problem. Even if it...

Re: New chain skipping

I have had a similar problem when 1. I used the wrong quick link for the new chain, may be a 9sp link with a 10 sp chain, it took me ages to figure that out :oops: . The new chain is an identical model to the old one, and I'm using the quick link it came with. 2. When I fitted a new RD and new cass...

Re: New chain skipping

I had something similar after replacing the chain and cassette once, and I had to in the end change the middle (most used) cog on the chainset. Then it stopped. The front chain rings are a little worn, but I can see the chain jumping over the REAR gears. Also, the skipping occurs on the smaller two...

New chain skipping

To improve gear shifting slightly, I re-aligned my rear mech hanger and replaced a worn chain. The cassette scrubbed up like new without any noticeable wear. However... The new chain skips every 1/2 rotation of the cranks/pedals on the smallest 3 or 4 gears. The smaller the gear combination, the les...
