Ultegra has a single central battery powering both front and rear shifters, so it saves quite a bit of weight here. We weighed the same battery at 53g when we checked the weights of theShimano 105 Di2 groupset. Actual weight:328g (including battery) Ultegra weight:261g SRAM Force AXS ...
The brakes of the 2023 Apex groupset are based on the well-established Level models from the mountain bike sector. Optimised for gravel, they rely on the flat-mount standard and deliver the same braking performance as those of the higher-end groupsets. SRAM have even thought of all the fla...
Totting up the claimed weights for individual parts gives a total weight of 2,845g, though that doesn’t include gear cables or housing. In any case, that’s 105g lighter than the actual weight – 2,950g – of our 105 Di2 R7150 test groupset. Once you account for brake hoses and...
In order to improve the reliability of decision-making, this paper proposes a new method for determining decision-maker weights based on comprehensive weights, which is used to distinguish the professional level of decision-makers. Finally, the PDS decision-making process is elabora...
expert weights in one cluster when judgment matrix consistency is identical.Finally,the optimal scheme is determined by the sort function of vague sets.An example is taken to show the feasibility of the model.The study provides a feasibility method for investment decision of water resources ...
Aimed at the ranking problem of multi-attribute group decision-making for vague values,a new score function is proposed.The close degree of vague values is defined,combining with the information aggregation operators and experts' weights,and then a new method for ranking group decision-making is ...
