Dealing with accelerated wear on components from long rides
I like riding 200km+ every weekend and the adding in commuting and brevets etc. Sadly this is wearing out my gear at a foolish rate. Doing 500km weeks soon kills off a chain and cassette not to mention the pedal bearings etc. So... at what price point are components the most durable (light or pretty is irrelevant) but not too expensive?
I found on my touring mtb that Deore/slx seems to be the best bang for your buck in terms of function and durabiltity. But, in the roadbike world whats its equal? Tiagra? 105? As I use my road bike more and more for brevets its starting to suffer from acceralted wear out syndrome. Fixed that on the mtb by going to higher spec (slx/xt/xtr) but the roadie is a commute as well and it needs to cost less than $2000 to replace which is where my mtb is at in its current spec.
Currently running entry level specs (2300/sora) and its quite frankly not up to the the task I need to perform.
