Shimano makes (as example) rear ders that retail for as little as $15 or over $700, the Deore line actually sits about at the half way point WRT numbers of lines (not, though, in price). Most don't consider Deore as entry level in the least. I suppose one could further refine their scale and only include the lines that are designed to appeal to "sporting" riders (and dropping out Tourney, Altus, Acera, Aliveo and other lower cost lines) and make a claim that Deore is the base of the "performance" lines. But that's using opinion to support marketing rubbish talk.


Deore is found on many $1500ish touring bikes because it handles the gearing range that loaded touring needs, is well enough made to not be a demerit, works well, is quite durable in the aspects that actually count and isn't too expensive (at around $60 if bought separately).



I agree with the recommendation of using Deore but not the "entry level" description.


A quick viewing of the Shimano website will give you the complete and current Shimano line up and in less time then it took to write this. Andy
