So Shimano dropped GRX 12-speed mechanical today - Here are my technical notes - Shimano is billing 3 options: 2x12 = 48/31T double with 11-36 HG cassette Basically this is the same crank gearing, but a cassette with a little more bottom end and the cassette will fit all the HG freehubs on the market  1x12= 42T or 40T single with 10-45T microspline cassette and 1x12= 42T or 40T single with 10-51T microspline cassette  So, what is interesting here is the 1x groups have been expanded, for the left lever you can still get a brake only or a integrated...

We looked at both the geometry and marketing surrounding “all-roads” bikes ————— Quick geometry analysis - most bikes fall into this range but there are outliers  - - Road bikes for European style stage racing: Head and seat angles: 73/73 Chainstay: 405-410 Bb drop: about 67-70 - - Gravel race bike: Head and seat angles: 72/ 73-73.5 Chainstay: 420-425 Bb drop: about 70-76  - - Notice the differences?  Gravel relatively 1d slacker and lower and longer stays  - - What about “all-roads”?  (Bike with tire clearance 35-40c) Head and seat angles: 72-73 / 73-73.5 Chainstay: 415-420 Bb drop: about 67-71 ...

Hello -  We heard you like interesting builds and original gravel content - Check out our latest build (full spec below)  Is it just a 90’s mountain bike? Is it just a hardtail? We feel there are three things that make this gravel build unique:   Titanium frame -lower carbon footprint to plastic frames- while offering high durability and that magic gray metal ride quality   Suspension fork - suspending the bike and rider is safer, more comfortable, and faster  Bigger gears and ring are lower drag while offering the same ratios- We took our shot at the 11-51T cassette hack...

AllRoadsRacing.com’s guide to Shimano DI2 12-speed   This guide is intended to be used as a purchasing guide for buying a complete DI2 performance road groupset. We primarily seek to answer these questions: What are the most meaningful differences between Dura-Ace, Ultegra, and 105? Is there a more optimal outcome by mixing groups?  What are the major competitive differences with SRAM AXS?    This guide is not intended to be technically comprehensive in all details of these group-sets, it is intended to weigh the most meaningful differences in performance, weight, and cost.  What are the most meaningful differences between Dura-Ace, Ultegra,...
