dse1969 said:I had only used Shimano Dura-Ace 7800 until I changed to SRAM Red about 6 months ago. I have two bikes & would regularly ride both as both were equipped with 7800. Since changing to SRAM Red on one of my bikes, my second bike with 7800 has been riden once! SRAM Red is vastly superior to 7800 and so it should be given it came along 6 or so years later (I think!). My only critisism of SRAM Red is the difficulty I have getting off my rear wheel when I need to change a tyre, tube or cassette. The rear wheel doesn't just drop out like it does with Shimano. You end up getting covered in grease & filth & doing this in a race (which luckily I haven't had to do YET) will definately take longer for the wheel change which means a longer harder chase!
I have just read the review of Shimano 7900 with great interest. Having not riden it yet, I can't really comment but can see through the pics & explanation that it could have been better! I'm not a big fan of the dark brushed look & would urge Shimano to bring out a Silver version (as per 7800) asap. That couldn't be that hard for a comapany as big as Shimano?
Alright, one more question that someone out there might be able to help me with. Although I ride SRAM Red, since wearing out my first chain & cassette, I have been mixing groups. I've been running an Ultegra cassette & dura-ace chain which work brilliantly, infact better than the original SRAM chain & cassette. I have heard that the Red chain and cassette have since been improved. Can I run the new Dura-Ace 7900 chain & cassette with the rest of the SRAM Red groupset? The new chain & cassette sound great so I hope I can!
See ya on the road!
Yes you can use a 7900 cogset($300) and 7900 chain($70) with Sram but remember, cogsets and chains are consumables. You get no performance advantage over those small number of grams saved.
105 10s cogset and chain works the same, has the same longevity as the lighter by a small bit and MUCH more expensive stuff.
