I have a Dura Ace drivetrain on my tri bike, and I’m looking to switch from the stock 11/23 cassette (53/39 chainrings) to something a little more forgiving on the low end without giving up the high end. I see that the SRAM 1070 cassette comes in an 11/26 option, which seems ideal.
Is this SRAM cassette compatible with my Shimano drivetrain?
I’m going to be replacing the chain at the same time. Should I go with a SRAM chain or Shimano or ??? Does it even matter?
Does anyone run this cassette (1070) that can compare shift performance to a Shimano cassette?
Does anyone run this particular cassette (11/26)? If so, are you happy with the jumps?
I run an 11-26 SRAM cassette on my road bike. I am happy with it, since it is my road bike. On my TT bike the gaps are a bit much, but it works if the ride has 12% grades. I have been using an Ultegra 10sp cassette on my road bike recently and have not noticed a difference.
I do not use the SRAM chains anymore. I am using the KMC chain. It is the direct replacement and significantly less in price.
As far as components go, all manufacturers state that their cassettes should only use their componentry. Although I have gotten all 10 speed components to work with one another and with ease. It seems that 10 speed is pretty much close enough to one another that the spacing even though slightly off still can and will match each other. Shimano and Sram are the closest which was done for many reasons from Sram. Campagnolo on the other hand if can be helped should be used with only Campy. KMC and Wippermann chains can pretty much be used on all drivetrains and most often are cheaper with not many a bad thing being said about them (to the best of my knowledge). Although I know that there is somebody out there that has broken three, but then again everything breaks. If you sell one item and always see it fails, does not mean other companies are not experiencing the same failures that only they will see.
I run the 12-23 1070 on my main road wheel. Use it with both SRAM and Shimano shifting…no issues. Also, use Wipperman and SRAM chains with it…they work the same. I also interchange Shimano cassettes among the same bikes. Never need to adjust. I find the Shimano cassettes to run slightly better than SRAM, but not that much.
If you don’t know how to do derailleur adjustments, take a class at your local LBS. Besides needing to change tires, this is probably the best skill to have.
