It seems a lot of people are changing to 3/8 chains / chainsets now as chains are becoming stronger.
As I'm due to change a chainset on a training / commuter fixi I've been told I might as well go on to 3/8 as it means shimano / Stronglight etc standard cogs and chainrings are useable meaning good choice and reasonable prices.
As I've to buy cranks, chainring and rear cog / chain thought now is the time to change if so.
Or should I stick to a proper speedlight type crankset and 1/2 set up meaning slightly more expensive stuff?
Any thoughts or recent changes / opinions?
do you mean 1/8th v 3/32nd?
I've used both 1/8 and 3/32 setups and felt no difference. Only used 3/32 for my last builds. I dont skid or ride very agressively though but KMCs SS 3/32 chains are tough and can take some beating.. Broke 2 tools trying to cut a chain.
Sorry, yes thats exactly what I meant. don't know why I put the above and I do know imperial and metric.
I run 1/8th on my fixed and ss bikes, regardless of chainring size (i.e thickness). Narrower rings will have a bit of room but wider (1/8th) teeth won't run in 3/32 chains properly. Plus 1/8th chains are not flexible, 3/32nd chains are all designed for derailleurs, seems wrong to run them on single cogs.
And they tend to be more expensive for similar quality.
There are chains available for singlespeed/track use in 3/32 too.
I've run both sizes over the years and can honestly say you won't notice any difference. I now use 1/8 cos good chains can be bought under a tenner. Better to change chains regularly to save wear on chainring & sprocket!
Understand the 1/8th is stronger but the rings and cogs seem to be cheaper and easier to obtain a bigger selection with 3/32 (ie shimano ss freewheel on a flip flop in 3.32, some BMX cogs) and as the 3/32 chains seem better now, at least some are, it seems sensible to use these as interchangeable with geared bike stuff so less to dedicate / store.
Not sure that 1/8 is actually any stronger but even if it is then a non issue as I don't break 3/32 chains. Much more choice in 3/32 from cheap/low quality to expensive/high quality and all those in between.
The 1/8 is on average going to be heavier too so again no point in extra weight for no reason.
I have used all 3/32 for years fixed and SS and never had a problem. Plus I really like the Wipperman Connex 808 chain which is cheap at £15 and lasts well through all weathers.
Connex chains are great, think I'm going to change to 3/8 then as have a spare connex 708 in the garage.
Probably put a Stronglight speedlight crankset and zicral stronglight chainwheel on and see whats in stock for the cog.
