I noticed more manufacturers offering carbon eMTBs in the past couple years. Bulls and Specialized for example. One pays a premium for these bikes compared to their aluminum counterparts. Besides the seemingly insignificant reduction in weight and perhaps increased esthetics (cool factor), is there any performance or durability benefit offered by these bikes? With exception of the hardcore MTBers with money to burn, IMO I really can't see a significant advantage or market for them. What's your opinion? What do you think is driving this niche segment of the market?
