Bike Check: Taylor Vernon's Custom Painted Prime Rocket
"the Active Spider has been adjusted to 12 degrees to up the freedom against chain forces." Even though I walk through the valley of the Les Gets. I will fear no roots on my far TOO HIGH ANTISQUAT KINEMATIC, for OChain are with me; your CHAINGROWTH and PEDALKICKBACK damping effects, they comfort me

Review: Reserve 30|HD AL vs Race Face Turbine Wheels
@powturn: "it is the straight-pull spoke heads unloading, rocking, & creaking in those large, resonant straight-pull hubshells” Concerning the alleged resonance, the hubs containing only a very small volume of air vs rim / tire, if there is resonance it will be at this level. Hubs have nothing to do with it. The twang perceived by kaz is due to the movement of the spokes against each other at their crossings. it has nothing to do with the potential unloading of spoke heads on straight pull hubs which is an urban legend. A pullout of the heads could happen in the case of very unbalanced spoke tensions or untensioned spokes, which would instantly result in a donut wheel... Which could happen to any wheel in this case since the spoke nipples are not fixed to the rim either and only the tension of the spokes keeps them in place… Moreover, even if jbend spokes cannot turn on themselves at the hubs, their head is not fixed to the hubs and can also move slightly. Anyone who has ever dismantled an “industrial” wheelset with j-bend hubs will have noticed the slight wear area at the eyelet and at the spoke/hub contact on the flange, which shows the slight movement of the j-bend spokes relative to the hub. The only two things that can actually be criticized about straightpull wheels are: 1. difficulty in re-truing them in the case of very loose wheels or at the start of assembly. As soon as tension is sufficient, friction at the spoke head/hub contact becomes such that you can true them without a clamp. 2. spokes length taller than j-bend wheels and the more open angle between hubs/spokes making them potentially more flexible Straight pull assemblies have a mechanical advantage over the j-pull because the spoke tension is perfectly distributed and exerted at the hub, not partially distributed on the hub flange, which reduces the risk of the spoke head breaking and improves the tension distribution across the entire wheel. This also allows you to build wheels with greater tension if you choose the right spokes and rims (tensile strenght vs. elasticity, c.f. use of alloy spokes in high-end straightpull wheels). It is true that straightpull wheels do not tolerate mediocrity and even less an industrial assembly with unequal tensions, poor quality spokes (high elasticity steel), etc… In the case of Kaz, this phenomenon is aggravated by the fact that the wheels are 28 spokes vs 32, (which explains about 50 g of the weight gain vs the reserves). Low spoke tension or bad tension balance explains the more "compliant" feel of the wheel and the noises heard. In general – and even more so with a straight-pull wheel – you have to check spokes tensions from the first serious ride, tighten and balance if necessary. The more tensioned and balanced a wheel is, the more rigid and responsive it will be. A quality straightpull WS, even with 28 spokes, is at least as durable as a j-pull WS. There's a reason I9 offers this setup on their high end wheels, and j-pull setups on their low end/industrial wheels... As of durability, Sam Hill achieved all his EWS successes on straight pull mavic wheelset, which is a testament to them given the beating the same pair of wheel takes on 2 days. SP Mavic’s Deemax is the most titred wheelset ever on the whole WC DH.

A Deeper Look At RockShox 2023 Fork Tech
Get yourself a Charger 2.1 if you need it, Charger 3 is really not on par with yet...

A Deeper Look At RockShox 2023 Fork Tech
Yep ! Thumbs up for a very factual article. Buttercups reminds me of older elastomer forks like Judy XC circa 1995, and I was wondering since RS released it why they didn't propose different hardnesses for their elastomere, like on Shore scale, to adapt for riders weight... But anyway it looks like they have come full circle ... Yo dawg, I heard you like forks, so we put a Judy in your Zeb so you can Judy while you Zeb !

Ochain Components Release the New Ochain•R
@lkubica: Yep. My priorities when buying a frame 1. Material/conception/realization 2. geometry (slack enough, low BB, steep seat tube) 3. low AS/PK, low and progressive LR 4. low or neutral AR Knolly nicely match these points, if you think of another brand, please share !

Ochain Components Release the New Ochain•R
@stormracing: may I suggest to directly buy a frame with low AS/PK values instead of trying fixing it with expensive patches ?

Ochain Components Release the New Ochain•R
This is a workaround for the negative effects of having a frame with too much AS/PK, as 90% of current bike market, because people are stupidly buying the "climb like a goat, descend like the GOAT" thing without questionning what it implies to have a transmission that positively lock your suspension when you are pedalling...

@lkubica: next time get directly a frame with low AS/PK, you will have all the benefits from ochain without actually needing (or buying ) one...

Review: O-Chain's Active Spider Adds Suppleness & Silence
Or directly buy bikes with low AS/ pedal kick-back and progressive ratio (i.e. well-designed kinematics) and stop the linear ratio/high PK mafia...
