Why is DRAM most preferable to SRAM

MTB gears comparison: Sram vs. Shimano

With the current 1x12 circuit, Sram says goodbye to the derailleur forever. On the other hand, there are Shimano gears, which with its double and triple options still hold on to the front derailleur.

Even shifting gears is now a question of philosophy and divides the community changing gears into two camps. Those who like to do without a derailleur due to the tidy look, simple operation and less weight and the others who prefer the wider range of gears in connection with a derailleur to any compromise. With the just presented Eagle 1x12 switching groups, Sram breathes more universality into the single drive. The key to the increased bandwidth lies in the huge 10–50 cassette with twelve pinions. BIKE has already taken a closer look and compared the new groupsets from Sram with the current Shimano MTB gears with 1x11 and 2x11 gears.

Sram vs. Shimano: 1. Weight

Based on the manufacturer's information, Sram retains the upper hand with the two new Eagle groupsets when it comes to weight. The XX1-Eagle weighs 109 grams less than the 1x11 Shimano with 11–46 cassette or 136 grams less than the 2x11 Shimano with 11–40 cassette.

Sram vs. Shimano: 2nd gear range

Depending on the cassette gradation (11–40 or 11–42), the Shimano 2x11 configuration has a range of 503 to 529 percent. In comparison, the Sram-Eagle draws almost the same due to the broadly graduated 10–50 cassette with 500 percent and only one chainring and opens up a much wider range of applications for the single rider than before. The previous 1x11 circuit from Sram was already over at 420 percent.

The table shows the tooth gradation of the common cassettes with Shimano (single / double compatible) and Sram (only single). With the smaller pinions, Shimano has one more gear step with only two teeth (green). In the larger sprockets, Sram is partially more finely graduated.

Sram saves weight
In order to use the same gear range, Shimano riders have to use 2x11 with an 11-40 cassette. Equipped in this way, the top group from Sram, the Eagle XX1, saves 136 grams on the scales.

Opinions on the duel 1x12 vs. 2x11

Urs Huber, Team Bulls / Shimano:
"In the marathon, many routes are unknown. With the double crank you are protected and still have reserves. Thanks to the Di2 with Syncro-Shift, the shifting effort is also low."

Organizer Urs Huber

Nino Schurter, Team Scott-Odlo / Sram:
"A big advantage of the 1x12 shifting system is the better efficiency. The larger cassette means that I can also use a larger chainring at the front, which means that the chain is less deflected."

Peter Nilges, BIKE test manager:
"Increased bandwidth, low weight and crisp function. The new 1x12 gearshift (Sram Eagle) impressed on the first test round and proves that single drives don't just have to be for specialists. We are curious to see whether the good impression is also in the Continuous use confirmed. "
