ideal size for a ss chainring

[dyna-ti]

Whats the best size of c/ring to use on a single speed set-up
I've put on a 44 ,but keep seeing 32 or 34 available for ss in the shops,i know i all depends on the rider,but an average size would give me a better idea
Also seems cheaper to put on multiple speeds than to have just one :?
The last time i set up a bike for gears was with a 7 speed rig 42T+ 12-23 on my commuter
I'm thinking that would be the way to go ,i mean :shock: bloody hell £30 for a tensioner and what is really only, half a derailleur and the basic half at that
but enough from the rear end
who does what ? 30T or 32T or 42T or 44T

Depends what sort of riding you're going to do (and where).

I'm running 32T chainrings and 18 or 19 tooth sprockets - for the sort of riding I do and where I do it, I couldn't go any higher than that.

There are tensioners that don't cost £30, if you have a look around -

Plus, there's always ebay of course.......

i think the 38 tooth crank im selling would be ideal
lol shameless or what

Make yourself a tensioner, or do without

Stick with your 44t ring, & get a sprocket to suit... 44 / 21 here.
2:1 or there abouts seems a fairly standard starting point.

+1.

maybe a touch lower for serious trail work. i'm running 32x17. an advantage of the smaller ring is greater ground clearance, but you may need to change the rear cog as well to keep the ratio where you want it.

A very good point (and one that I forgot to make !). Not having a 44T or 42T ring makes getting over logs and rocks noticably easier and without the same risk of tooth damage. (well, chainring teeth anyway )

Something I have been meaning to ask for ages....has anyone fitted two rear cogs (with spacers in between naturally) to allow a 'manual' gear change to a different ratio? For example a 14 and a 16 or a 16 and an 18?

The following words of wisdom stolen from Marshall Hance at Endless Bikes

www.endlessbikes.com

To maximize drive train efficiency, we recommend the most inboard chain line possible by use of narrow bottom brackets and inboard mounted chain rings. Narrow chainlines put significantly less bending force on your frame’s rear end. More snap, zip, zoom!

Looking to increase drive train life AND rear end stiffness? Our high tooth count Kick-Ass-Cogs allow super smooth big gear configurations (such as 44/24) which minimize chain tension, improving both chain and gear wear, and pedal smoother to boot.

Want a better gear for pedaling to the trail? Run two chain rings up front and a 1mm spacer between two Kick-Ass-Cogs in the back for two perfect parallel single speeds! To minimize readjustment concerns, simply have the sum of each gear combo equal the other. For instance 36/15 and 32/19 (36+15=51, 32+19=51) are a great pair for pedaling from downtown Asheville to go ride Pisgah.
