What's the Deal With SRAM's DUB System? More Questions
@WAKIdesigns: Totally agree. Ever had shimano XTR and XT HT2 cranks with PF92 and BSA73 bottom brackets. Got only one issue with hope bearings from pf41 kit, replaced them by enduro bearings and no issues since 2 years despite mud, sand and snow. Got a GXP crank once with PF92 plastic cusps from sram, it start to creak and drag within 2 weeks of use in summer conditions... From my little experience, it seems that bearings and bearing interface quality are more important than everything else concerning 24 mm spindle crank. As for weight a shimano XTR crank+ BB is on par with everything else at sram for same price.

Mondraker Foxy Carbon RR SL Review
@brianpark: Yep pedal kickback will be nice too since you provide AS curves, and if possible in the same transmission ratio for all the bike you test for comparing apples with apples - and maybe a little less than 32/50 since 50t eagle like cassette are not ubiquitous - maybe 42 t should be more representative.

2018 Canyon Torque - First Ride
Too much AS/PK build on gravity-oriented bikes (new spectral, new torque). High speed cruising is 20% (>20 km/h) of my time on bike, the remnant is climbing, low speed rock crawling or rooty/rocky trail on which I need a lot of traction that is killed by high AS/PK. I know most of bikes today must climb well and go down well (which is a lié) meaning strong AS, but obviously it means a lot of chain growth, particularly on the granny ring, and the suspension operation became strongly dependant of the weight distributed over the pedals. I will not buy a bike with more than 70% AS at sag for 32/21.

New Products and Innovative Tuning System from Vorsprung
However there is a lot of BS/marketing/emphatic turn in this press release that does not suit to a rigorous scientific communication... For instance showing plots that looks techy but demonstrate absolutely nothing, with no units or abstruse axis labels. Maybe it looks like science for you, but for scientists it looks like marketing BS. You must be aware that there is really nothing new in what is described above, and most of good suspension tuners does exactly the same job (PUSH, AVA, Novyparts, etc...) in getting his own combination of valving /shimstack/piston design for a given ratio curve/rider weight/shock type. And most of them does the same job for half the vorsprung price...

Eminent Cycles Launches the Haste - First Look
@catfish9797: I guess that tracking on climbs has much to do with how much AS is implemented in the design, rather than the design type. DH rigs circa Straight 8 era were designed with a low AS/low pedal kickback, be it 4-bars, faux bars or others, which explain the good tracking abilities on climbs. Difficult to check the main pivot location on the Eminent cycle, but it seems to be quite aligned with the 32t ring, so I thing it's around 100% at sag in 32/18, maybe a little less. IMO, a good configuration is the combination low AS (around 70% at sag in 32/18 ), high LR with an air shock, shock and ratio progressivity preventing too much squat and keeping the suspension active while pedaling.

Press Release: Radon Product News 2018
Dear Radon, stealth bomber/figther doesn’t look anymore like a broken mirror, F117 was designed under Ronald Reagan, and edge design stops at the end of 2000´. Please update your design references.

Raaw Madonna - Press Release and Interview
"looks to have hit all of your preferred nails on the head: sizing, geometry, attention to detail, materials, and pricing" Yep, another expensive bike with stupid AS and PK value for a 160mm bike. Funny how they show AS curves but not PK... This bike will be an absolute horror on small bumps, square edges, slow rocky/root section, etc... Please press, marketing agent, etc... stop selling us the good at pedaling/good on downhill BS since from suspension kinematic this is not possible to get on a single pivot or FSR bike.
