Are you happy with the 46x18 (69") on your old bike? if so that is the gear to go for. As 790 said chainrings on single speed have a pretty easy life but there is no doubt that different brands can vary in hardness. Also they can vary in the degree of "roundness" Some nasty chainrings can cause the chain to run tight and slack because they are slightly elliptical. Impossible to tell in the shop of course.
Just seen this on the Velosolo website
***Token Track Chainset
A new track chainset from Token with traditional square taper fitting. Forged 7075 aluminium alloy arms with 144mm BCD (compatible with Token chainrings only). Complete with 1/8" 48t CNC 'Shuriken' chainring***
I am at a loss to understand how there can be compatability issues on a track chainset if the BCD is right but maybe it would be best to stick with Miche. -
Assuming that your transmission is in good nick I can see little point in changing both your chainring and sprocket so if you stick with the current 16 teeth I reckon you want a chainring between 42 and 46 depending on if you like to push or spin, and your route of course. Check the gear on your other bike ie teeth front and rear then come back and I will tell you what chainring would give you the same gear with a 16 tooth sprocket.

Happy to be contradicted. My daughter recently bought a Foffa and that came with 46x16 which I felt was too high. Years ago I was on a steady training ride on flat roads and there were about sixteen riders in the bunch, I went up and down the line to check and everybody was on 42x16. OK in those days we only had ten gears to choose from but I felt there was a lesson there. I am sure Jonario will be happy with 48x16, for sure it will be a big improvement on what he has now.

That is a track racing gear you have. I have assumed, perhaps wrongly, that you use the bike for just riding around, maybe commuting. If that is the case I think even a 48x16 could be too high so if you go for the 48t it may still be too high and you would have to get another sprocket as well. Have you ever had a road bike and if so what gear felt right for cruising?
The chainring from Evans looks fine. I have just checked the price of a TA 1/8th chainring at Spa cycles and I was shocked to see they are £34!! -
Back in the day when derailleurs were crap and nobody had any money anyhow guys would tour the Yorkshire Dales on 48x18. I used 50x20 which is a little lower because I was a useless climber. With your 52 ring a 20t sprocket would give you a similar gear to 48x18. Might be worth considering if you are on fixed and can get a cheap sprocket
Single speed is always a compromise but unless you have a stiff climb every day 48x18 will be OK.
3/32" and 1/8th" are the nominal widths of chains. I couldn't get your link to work.
What is your back cog at present? -
165mm is for sure the crank length. 144 bolt circle diameter is the old Campag road standard and I believe is current on their and many other track chainsets. It will take a ring down to 42t although 48x18 is the perfect riding around fixed gear.
Track bikes often have a 1/8th inch chain and ring/sprocket (slightly wider) but a "road" 3/32" chainring will work OK. TA make good rings in quality alloy.
If you go from 52t to 48t you may well have to take a couple of links out of your chain.
