Reader Story: Does Pedal Kickback Actually Happen?
@KJP1230: @KJP1230: Without idlers high pivot bikes wouldn't work. The idler doesn't necessarily make it preform better in terms of chain behaviour than a normal bike. The best situation is where the chain line is in line with the pivot (or virtual pivot point). it's just that the marketing has made the statement, "idler to reduce pedal kickback" but it should be caveated by "better than without an idler, but not necessarily as good as normal bike". It strange how marketing bullshit becomes technical truth and people will defend it with no knowledge of the behaviour. In fact magazines and media outlets are very responsible for propagating the un-truths too.... There's a good write up on Bike Rumour, with lots of bike brands (technical people) talking about their high pivot bike, they all understand the behaviour correctly, but the marketing team picks the bits that sound good and distort the truth!

Pedal Kickback is just chain vibrations felt through your feet!!!

Coal Bicycles' Prototype Steel 'Park' Bike
@Norman22: Carbon is lighter until you factor in damage tolerance. Since carbon is easily damaged you need more material, and hence more weight to make it tougher. I know I'd much rather have one steel frame that's perhaps a tiny bit heavier, than a number of light carbon frames that need to be replaced (or indeed you don't have confidence in) The answer is never as simple as you first think I've seen studies completed by colleagues in the aerospace industry that showed for many components (especially more complex ones) aluminium provided a much lighter solution. On one big project, carbon was chosen as a political rather than engineering choice. I kind of see the same thing with bikes and marketing!

Video: 'Upshift' Showcases Developing The New Production Privee Flagship Bike
Interested to understand where the funding for this came from. I'd be very surprised if a small bike company is generating enough revenue to have such a high tech facility.

Review: O-Chain's Active Spider Adds Suppleness & Silence
Watch any huck to flat slomo video, the chain goes super loose and flap about on impact to the ground. On most suspension designs, the upper portion of the chain goes into compression, i.e slack, as suspension goes up. How does this sit with the science of how this device is meant to work, it doesn't! But everyone who has an OChain loves it, so something is going on. "Calms down chain oscillations which leads to a quieter ride" is the truth and a very valid one, but I just find it weird that something is marketed when the science is so clearly wrong. Discuss....

First Look: Starling Cycles Adds Adjustability & Tweaks Geometry
@dickyelsdon: True, but there's also a of people out there who don't really care and are actually confused by too much detail in numbers. Stack is affected by fork length, so we present the accurate value. The impact on reach is petty negligible, so we just present the nominal value. Personally, I think we have plenty of adjustment in stem, bar height and roll, saddle rails, to fine tube bikes to fit most people. As long as the starting point is there or thereabouts.

First Look: Starling Cycles Adds Adjustability & Tweaks Geometry
@dickyelsdon: Numbers alone do not dictate how a bike rides, it is a sum of its parts. I think its easy to focus on specifics and get lost on the point of what we are trying to achieve.
