I'm a roadie and try to do as many MTB rides in the winter as I can. I'd ride more MTB during the warmer weather but the people I ride with only want to do road rides in the warmer months.
Help me with the MTB components and equivalent to the road.
The best to the lower level
Ultegra (the preferable you should buy)
105 (the minimum you should be buying)
Tiagra (the least you want to buy)
Sora (which you don't want to buy)
Where do these line up with Shimano and SRAM and where does the Shimano lineup with the equivalent SRAM.
Would you tell me if this is correct?
XTR Dura Ace? Sram X0 & X9
XT Ultegra? Sram X7
SLX 105? Sram X5
LX, no longer made
Deore Tiagra? Sram X3
Any others I've missed, is there a SRAM X1?
