Review: Fox Live Valve Suspension
@alexdi: A battery is just a battery! Granted, the Li-Ion will have a standard undervoltage controller which is universally required on all Li-Ion batteries, but the MCU that Shimano uses will communicate using a standardised protocol such as CANBus. Wouldn't be too hard to address the Shimano MCU with a message such as "Hey, how much capacity does the battery have left?". @Vertti83: I'd highly doubt that Shimano is encrypting *wired* communications to it's equipment over a simple 2 wire interface. What would the encryption achieve? Wireless is a different story, but I'd be surprised if that's also encrypted. Likely just a specific CDMA code to prevent interference and to offer a light layer of physical security. "2 Wire Interface" would also mean a standard protocol - which would more than likely be CANBus. (CANBus uses 2 wires, has the best SNR for outdoor environments). Developing your own transceivers for an entirely new interface standard would take a lot of R&D, custom silicon chips to be manufactured, silicons dies etc... not the sort of thing a company like Fox who manufacture suspension dampers would get involved in. Much more commercially viable to use a proven and existing system. But what would I know? I'm probably just an armchair engineer bashing my keyboard in the Pinkbike comments section spouting fancy acronyms! Probably.

Review: Fox Live Valve Suspension
@pads: haha sorry, I work with electronics so I'm just interested in where the industry's going! Open loop would be very risky - no feedback could mean the solenoid get's set in the wrong position for a gradient change? I've got a bad feeling it's as you've said. SPDT switch on a solenoid that just opens/closes a value dependent on gradient and impact.... hopefully it's much more involved with a variable value & a little bit more computation! Milspec in being able to stand -10 to +80 (or so). This sort of stuff will need to be able to withstand harsh Canadian winters! I understand why wireless introduces latency, but surely there could be a standardised wired protocol? Yes they will all use CANBuss - but if everyone agreed on a common set of rules for using the CANBus address-space/identifier then it'd be better for the industry as a whole. At the end of a day, a 7.4-volt Lithium Ion battery, is a battery. If the battery datasheet aligns with another manufacturer's (discharge rate, capacity, max/min voltage etc) - no matter what "brand" you print on it - they're compatible. Even a sensible choice of SMPS would allow a Di2 battery to be used in this system... either as you say Shimano doesn't want to play ball, or Fox want to seek another method of grabbing cash. If only someone specificied a standard set of connectors on an e-bike battery for: shifters, dropper, groupset and suspension... or am I living in fantasy land?

Review: Fox Live Valve Suspension
Could you elaborate on the word "algorithm"? Would be interesting to hear whether they've opted to go with a classical PID Control method or a modern State-Space control for preventing oscillation in the control of the solenoid valve. What embedded systems have you used? Did you need an FPGA for the speed you wanted or separate MCUs? ARM or AVR? 8-bit or 32-bit? How are you coping with temperature variations - is everything milspec? Surprised at the inability to integrate into Di2. If Shimano uses High-Speed CANBus - speeds of upto 1MBit/s could be achieved. Bicycles are in a low SNR environment too so don't see why this isn't possible... These cables are also in a rugged environment, so are likely shielded too. All it would take is for Fox, Shimano and SRAM to adopt the same H/S CANBus Protocol and all their devices could play nicely with each other. Work together and give each device its own specific address space and signalling. Heck - it would mean that you could use a Shimano motor, with an electronic SRAM groupset, with Fox Live Valve....... but that would mean corporate partnership... and you wouldn't be able to force customers into buying your entire device range... which is not a profitable business model. Would be a pro for the consumer, but big con for the likes of Fox/SRAM/Shimano. The downside with the introduction of electronics onto a bicycle is that you take the power to maintain your ride out of the consumer... for a "low" (read: high) fee for the software to interface with the devices. Additionally, every brand will inevitably use their own comms protocol, meaning lack of compatibility between devices. It also means these companies can also withold their protocol too to prevent 3rd parties from manufacturing alternatives and adapters thus narrowing the market and creating a monopoly. I'd personally like to see each company publish what comms protocol their using and a specification on how their devices talk to each other. This opens the door to 3rd parties such as "One Up Components" to produce alternatives for the consumer and keep cycling "open source". The nightmare scenario would be that if you wanted to upgrade your shock in the future, you'd have to change your Fork, groupset, motor, battery AND controllers... because they all work on different protocols. Nah, I'd stick to good old fashioned cables and hydraulics...... interchangeable between all brand components.

Whyte 905

$650 GBP
For Sale is my 2014 Whyte 905 with additional upgraded components. I had purchased this bike directly from Rockin Bikes myself brand new, and has been serviced regularly over my period of ownership. We are a family of cyclists, and the bike has been washed at least after every-other ride with Muc-Off products and lubricated with quality oils and grease. I am selling this bike as I am moving back to Full Suspension and racing after a period of riding Hardtails for the past 5 years. A review of the bike at the time of manufacture can be found here: https://www.bikeradar.com/…/prod…/review-whyte-905-14-47992/ This bike will be perfect for anyone looking to have a Hardtail for riding in the winter to conserve their more expensive Carbon framed bikes, for anyone looking to get started in mountain biking and want an excellent bike to do so, or for someone who wants to go back-to-basics (as I did) and return to a hardtail to re-learn essential skills. This bike is a "hardcore" hardtail and is designed to be ridden as such. With a slack head angle and moderate seat angle - this bike is designed to be ridden Downhill as fast as possible - and to climb gently back to the top. This bike is more than capable of handling trails at the Forest of Dean, Gawton, Tavi Woods and any trail on Dartmoor. Infact, in the right hands, you'll keep pace with less experienced riders on Full-Suss bikes. If I had more room in the garage I'd love to retain the bike, however, with limited room I must sell. Please bear in mind that this bike is 4 years old, and will have the odd marks here and there from cable rubs or paint chips. However, the fork stanchions are immaculate and free from scratches/dents/chips and are welcome to be inspected. This is due to the heavy duty Mudhugger FR Mudguard, which I highly recommend (not included in sale). Full Specification: • Frame - 6061 Hydro Formed T6 Aluminium, Custom Drawn and Multi Butted, Tapered Headtube, Get A Grip seat clamp system, Internal Stealth Reverb routing • Fork - RockShox Revelation RL, 27.5" Lock-out, Maxle Light 130mm Travel, Fast Black coating, Solo Air, Adjustable Compression and Rebound, Tapered Steerer w/ Low Friction Seals • Headset - FSA No. 57E Orbit ZS, Sealed Cartridge Bearings, 1.5" Lower, 1 1.8" Upper Bearings • Rear Hub - Hope EVO II with StSt Bearings, 10 Speed, 32 Hole. • Front Hub - Alloy, Double Sealed, Cartridge Bearing Hub 15mm, 32 Hole • Spokes - DT Champion 2.0mm Black Stainless with Brass Nipples • Rims - Whyte Trail 21 Offset Disc Rims, 32 Hole • Tyres - Maxxis Minion, 27.5" X 2.25" 3C Folding Rear, Schwalbe Magic Mary Folding Front • Shift Levers - Shimano Deore, 10 Speed, I-Spec • Race Face Narrow Ride 32t Front Chain Ring • Rear Mech - Shimano SLX, Shadow Plus Clutch, 10 Speed • Cassette - Shimano HG-81 SLX, 11-36, 10 Speed • Chain - Shimano HG54, 10 Speed • Crankset - Race Face Ride, 36-22, 10 Speed, Compact Double • Bottom Bracket - Race Face • Seatpost - Brand X Ascend 20mm Offset, 30.9mm x 400mm, 125mm Drop • Saddle - Whyte Custom, Triple Panel Design • Handlebar - Funn Full On 780mm Wide 35mm Diameter • Stem - Race Face Chester 60mm, 35mm clamp. • Grips - Lizard Skins Peaty Special Edition • Front Brakes - Shimano BR-615, 180mm Rotor • Rear Brakes - Shimano BR-615, 160mm Rotor • Brake Levers - Shimano BL-615, I-Spec • PEDALS AND MUDGUARD NOT INCLUDED • Weight - 11.8Kg
