And not by very much either, I would go with tiagra unless you want 105 to match the rest of the groupset.they aren't more durable, just lighter.
Aren't 10 speed chains and cassettes more likely to wear out quicker, as they have to be manufactured thinner to fit the extra cog into the available space?
Back in the old days, it never crossed my mind to change a cassette or chain on my Simplex 5 speed gears!

It needs to be updated too " Break Out Another Two "Boat is an acronym, for Break Out Another Thousand...
Or a SRAM cassette, as they are cheaper and lighter !
Is it the general case that the higher the spec of parts, the quicker they wear out? I have 9 speed Tiagra kit on 2 bikes.
My 4 year old Tricross has done 9500 miles and at a rough estimate has used 2 cassettes, 2 chains, 1 bottom bracket, and is only now needing the chain rings replaced (probably just the middle ring). Shifters are original, and an occasional squirt of ACF50 keeps them sweet. Cost of parts has been reasonable, using ChainReaction, and all repairs are DIY..
The Secteur has done about 2500 miles and everything looks as new! It doesn't go out in the rain though.
I am of course, a canny Scot.....!
It's only the Secteur that doesn't go out in the rain. There are another 5 which can get wetA Scot not going out in the rain? you'll be housebound then![]()
