Hi I need to get me some more chain lube, usually use the dry lube as 95% the time I am out in dry conditions.... Currently I use the Muc-Off C3 ceramic dry lube but have heard that Squirt is a good option.. Out the two which would you recommend? Stuart

I have an old but never really used MTB in my lock-up that I may get going for my stepdaughter during lock down. Chain last time I looked was rusted solid. Should I just pony up a few quid for a new one (6 or 7 speed at a guess) or is it worth soaking in oil etc to revamp? Just off to look at...

Keep meaning to buy some to carry, I have KMC chains, one is 9 speed the other 10 speed is the link the same or do I need separate ones?

Hi, I am restoring an old bike and the chain looks like it needs replacing. But I am just not sure which would be right. A photo is attached, and it has 10 speeds. Is it possible to advise which would be the most suitable to buy? It's for my 14 year old son so doesn't need to be fancy, just...

Hi all, what is your advice on how to clean and lubricate a dirty MTB chain? My preferred choice is some GT85 on a rag, followed by some TF2 all weather lubricant, however this method doesn't clean Inbetween the rollers. A work colleague suggests rotating the chain between two nail brushes...

I bought a new chain for my Giant Roam 0. I shortened the chain but mistakenly removed one link than was required. Is it possible to replace the link or do I have to buy another new chain?

I've got a 6-7 year old MTB ex Halfords Voodoo with light to medium use and well maintained, used on flat trails. I'm now losing the chain on every ride. I don't know if its down to a worn cassette or chain or both. I've cleaned it up and lubed it with silicone lube, and adjusted the derailleur...

Hi there all, I recently came across a "LEATHER CHAIN CASE" on a vintage Raleigh BiCycle. It is pretty intriguing as I have never seen it before. Thus I appreciate to learn more about it. Hence I am here seeking more info. on this. Many thanks in Advance.

Initial thoughts are use a screw driver. The thing is when these are tightened up, a screw driver could not really be used because the `male` part is flush up to the line where a screw driver would be placed. So, in reality there is only a small slot either side to hold the `nut` from rotating...

I have just checked my chain that I replaced recently and discovered it is 1 link too long. It should be 108 links which it was until I added the quick link, making it 110 lengths. It is only noticeable if in small and the last 3 cogs on a 11 speed. My question is this. Should I leave it as it...

Photo 1 is in biggest rear cog and front on biggest ring Photo 2 is in smallest rear cog and front on the biggest ring. I feel that in photo 1 the angle of the rear derailleur is a bit too much??

Today I checked bike chain stretch is at 0.75. So should I replace the chain now? To avoid cassette damage or wait for 1.00. I don't want to replace the cassette at the same time as this will be quite expensive for me. I've only done around 900 miles on this chain, meaning that I would have to...

Just putting the question out there amongst the cycle chat populous. In summer I use dry lube and in winter wet lube.I mickle the chain every week and apply fresh lube. Years ago we all used normal oil. What are the benefits of specific lube (not brand specific),over oil from an oil can...

Hi all, I have a bike that's done roughly 4000km in 2 years. I’m about to change out the chainrings and cassette which seem to have plenty of life left in them, I'm just switching out for some lower gears. Having checked my chain with a chain checker tool it’s not worn enough to require...

Been testing out a modified partial chain case I made for my commuter bike at the start of this winter I am using a Sram S7 hub gear and it would only really work with a hub gear or single speed ,in the past the amount of road filth that got on to the drive chain was just a filthy mess ,so I...

Sixteen years ago, I had my GT Outpost converted from a 21 speed derailleur to a 5 speed SA hub. I'll quickly add to forestall any SA detractors that apart from an issue a year later, I've had no problems with the system ever since - ! The chain tension was provided with a Surley Singelator...

This cover thingy (not sure what it's called) is wobbly and I guess rubbing on the chain a bit. I thought it would be a simple tightening job. One side is an alan key which is already really tight...I took it out again and retightened but it seems that doesn't affect the position of the plastic...

I was amazed to see this https://www.bikebiz.com/rehook-now-stocked-by-halfords/ - a) because it begs the question of why the chain falls off a well-maintained bike, and b) what fingers can't achieve either with a bit of plastic bag as protection, or a plastic glove freely available from...

I'm building a Frankenstein bike out of salvaged spare parts , its going to be a 1x , 22" Coyote hardtail MTB frame,rigid forks, minimal gears, an mtb touring hybrid kind of thing built for comfort and load carrying with panniers. I've rummaged in my pile of bits and come up with these Shimano...

What would have the biggest impact on a chains life, worn off particles from the chain itself or foreign (sprockets and road and air dust) particles? A chain is steel, a sprocket is (mostly) aluminium. Worn off particles usually corrode. So oxides of these. Which oxide is hardest (and thus...

Hiya, i bought a vernier calliper a few weeks ago, so I am after using it to measure for chain wear, anybody know the specific readings I should look at for good to worn and over , metric or imperial over how many links, Cheers

My trusty old (and very cheap) chain tool of 25-30yrs service has finally failed. It has travelled many thousands of miles in its role as my emergency roadside repair tool as well as being my workshop chain chopper. Currently looking at two possible replacements. As these are from reputable...

In the light of constant misrepresentation of the effects of a worn cassette on a new chain, I thought I'd explain why a new chain cannot be damaged by a worn cassette. We've seen this stated here as gospel often, and again, this week. Firstly, we need to understand why a chain wears and what...

I replaced the chain on my 9 speed Sora after 2500 miles and get the occasional slip on the middle sprocket, by that I mean about half a dozen times in 24 miles. It is not always under load conditions. It did not do it before the chain change and was changed because of wear and no other...

I've just come across this wheeze for removing a fixie cog without using a chainwhip. Obviously the BB would need protecting unless you didn't care about the paint. View: https://youtu.be/5qIVEpyelP0

Hi I have a silly question if anyone can help.. I have just been out to check the bike over ready for a little ride Sunday, I have not used it for about 3 weeks due to the weather … I keep the chain well lubed with dry lube as I use it in the dry.. Now looking at it looks like the chain is...

Just been to Halfords to pick up a new chain. Tried to fit it and it appears way to short. It’s an 11 speed chain which I’m trying to fit to my ebike. I have a 11 - 48t cassette with a single front chain ring of 46t. If I run the chain around the largest gear on the back and the chain ring the...
