Thanks to the high ratio of the new 10-speed cassette from SRAM and Shimano with gradations
from 11 to 36 teeth, it is also with a 1 x 10-turn circuit possible, sufficient for fast and substantially flat cross country and marathon routes have bandwidth available. The chain is guided safely over a single chainring - chain suck and similar time-consuming breakdowns cases are virtually eliminated. The chain guide is flexible with each chainring size and can be adapted with spacers to different chain lines.
As positive 'side effect' can still weight off! 250 grams can be saved.
The example of the SRAM XX group -
less derailleur (about 115g)
Trigger left (90g)
Chainring 26 inner teeth (about 24g)
Kettenblattschrauben interior (approximately 7g)
Shifting and Case (1.5m approx 58g)
- Gives the minus 294g of unneeded components, plus 40g for the shift-up, equal to 254 grams of weight savings alone in the high-end group of SRAM!.
