Good morning,
I have been playing around a lot recently using only 1 chainring and a 8 speed cassette, over the last few months mostly 50x11-32 so I get the appeal of 1x7. But the thing that would worry me about a genuine 1x7 is that it is bottom of the range and only ever seems to be paired up with other components to hit a very low price point.
So are the compromises needed to meet the price point ones that you will be able to live with? if the Pinnacle is aimed at very low mileage and looking at the gear ratios, 36x14,16,18,20,22,24,32 it does seem to be, will you end up with big replacement bills very quickly as you are doing lots of miles and aren't the intended customer?
For example this particular bike has a freewheel which will probably have an impact on availability of higher spec wheels if you need a replacement wheel, I moved away from 7 speed cassettes quite a few years ago not because I needed or wanted 8 speed but because 7 speed had become the preserve of cheap wide range cassettes and I wanted a narrower range.
What about the saddle, another easy area to save money? Is Revoshift for you or will you end up hating it and replace it? After all you're not coming at this looking for a first bike, but remembering what your previous bikes were like.
There is also the problem that the link takes you to a page that says .. all riders and for 2018 we’re offering ... so you might end up with something slightly different.
Having recently bought a compactish framed bike I was surprised to find that a spare rack I had wouldn't fit as its legs were too long, so if you have a rack and panniers lying around that you intend to use, they might not fit.
Bye
Ian
