@andrewsdad you didn't mention if its a front triple or double, I ride a triple with a front 50/38/28 and a rear 12-23 (12-13-14-15-16-17-18-19-21-23), my low gear is 28x23 is as low as a compact double with a 34 inner ring and a 28 rear (32") and like
@JMAG pointed out big gaps in the rear ratios leads to the occasion of not being able to find the right gear, 90& of my riding is covered by the 38th front and the middle of the rear 15-19 so you can see I always have the right gear ( a thing not pointed out to people when being told compact doubles are the way to go) I get round most the roads around here on no less than the 38x23 be that on the 38th fron or the same gear on the 28th front which would be 28x17. Not much you can do with doubles to get both a low gear and a decent set of ratios, I did once have a set up of 26/38/48 on a 12-24 8sp it went I think 12-13-14-15-17-19-21-24, 48x12 is the same as a 52x13 about 105" and the low gear 26x24 is 28" or the same as 34x32, Most people won't push an 11th on any front ring of say 50 or 52 at any sort of decent cadence as it a massive 120" on a 50x11 and 125" on a 52x11 So I would drop it in favour of starting at 12 and have another gear somewhere in the middle.
Its easy enough to make up your own ratios, so if you get a couple of cassettes (8sp are pretty cheap) get something like a HG50 12-XX for the the starting 12th, than say a HG51 with a 11-28 to make up a 12-13-15-17-19-21-24-28 (other options are available) you could also drop the 28 and use the first 3 from the HG50 say from a 12-23 (12-13-14-15-17-191-21-23) to make a 12-13-14-15-17-19-21-24 leaving out the low 28th, to make up your own its simple, just remove the rivets holding the cogs together and separate them, as I said 8sp are cheap enough to do this.
