Replacing chain ring

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!!

Yeah, it's pretty much for commuting. I have current fixed gear bike with me, I have to check the ratio 2morrow, although I do vividly remember counting to 48 for the front chain ring. On that bike, I kinda struggle going up hills. So should I consider a 48/18?

Oh and even though it's a track gear with 48t it'll still do the same job as a non track gear with 48t right?
