VIA GT: 2x10 Technology
The SRAM VIA GT groupset builds on the proven technologies of our SRAM X0 mountain group and SRAM RED road group. It delivers fast, crisp shifts under any conditions. With a 48/32 crankset and an 11-36 cassette, the groupset covers an enormous gear range, perfect for the touring rider (24.5 to 119.8). Hydraulic disc brakes provide the ultimate in stopping power with minimal maintenance. The system's efficiency and light weight mean your bike will be nimble, agile, and fast. Cross-chaining is no problem - VIA GT delivers "rasp-free" performance in all twenty gears. The VIA GT group has the advanced efficiency of our race groups, in a practical, no-nonsense package. Fast, proven shifting tech borrowed from SRAM RED. 2x10 drivetrain works in any gear - no cross-chain worries. Large, easy-to-read gear indicator Hydraulic disc brakes. Sleek design.

Component brand SRAM has launched a new urban/trekking groupset called Via GT. It comes with super-wide gear ratios from a double chainset and 10-speed cassette.
The chainset comes with either 48/32-tooth or 48/34T chainrings and SRAM say the groupset is optimized (everything is ‘optimized’ these days) for a 11-36 cassette. If you work in gear inches, that 48/32T chainset with the 11-36T cassette, a 700c wheel and a 28c tyre will provide you with a range of 24 up to 117.- See more at: http://road.cc/content/news/61238-sram-launch-gt-urban-groupset#sthash.VMjexlYN.dpuf

Speaking of SRAM, soon after I installed the OX601D crank I paired it up with a SRAM “WiFli” rear drivetrain. WiFli is SRAM’s tritely named concept of combining a wide-range 10sp cassette with a 50/34T compact road crank, but I did it one step further with the Sugino’s 46/30T crank. With an 11-32T cassette, I had a lower than 1:1 bottom gear on the small ring. Of course, on most terrain I could simply leave the chain in the big ring, but that doesn’t make the 30T inner ring redundant nor does it diminish my appreciation of rings’ shifting. I’m a decent road rider who likes to spin. On a sporting ride, I like a 53/39T crank and spend most of my time in the 39. I use the 53T for fast groups and sprints. I don’t like compact road cranks because I can’t just comfortably sit in the 50T or the 34T. Instead I must frequently shift between the two and then make multiple shifts on the rear before I can settle into a ratio I like. With a 46T big ring and 11-32T, I can now sit on the big ring, but I gain a bunch of low gearing for especially low and steep climbs, or if I’ve loaded up my bike.
