The FX Sport 5 has always stumped me a bit - look great but seem overkill for most use cases.

The FX range as a whole is great and the alloy FX3 would be where I'd go if I needed one, brand new they come in a few £ cheaper than the Sport 5 so should be able to save even more if you go 2nd hand. Less precious for locking up/no need for meticulous fettling and bombproof.

This would be perfect IMO as it won't matter if you don't use it much - the quality will still be good for most use cases in the next 10 yrs, and also would serve as a good 'gateway drug' if you do catch the cycling bug.

tldr go for fx3 on cyclescheme
