Velocomp improves accuracy and adds key functionality to iBike Pro

We dubbed the iBike Pro power meter 'Best Electronic Widget' of last year's Interbike show, and this year's improvements only serve to reassure us that we made the right call. For 2008, Velocomp has added a wireless version of its iBike Pro and a heap of features across the board, all while cleverly making no physical changes to the head unit itself. The ANT+Sport-compatible wireless protocol also means the iBike can 'talk' to other so-equipped pieces of hardware, such as Garmin's new Edge 705.

The new wireless model now features a rear wheel speed pickup and integrated cadence sensor, as well as full heart rate monitor functionality. The new sensor location means that speed will now finally be displayed during indoor training sessions, but a new software feature will now also register virtual power output, too, as long as riders use one of the 'popular indoor trainers' that Velocomp has calibrated in its lab.

The updated software now includes an automatic correction feature, which can supposedly rectify any anomalies in the iBike unit's built-in accelerometer and also retroactively fix a bad calibration, and can now calculate the amount of braking time (and the associated scrubbed energy) in any given workout. Other software upgrades improve how the data is displayed and analyzed, and new firmware increases the head unit's battery life. Last, but certainly not least, a new calibration procedure can now more easily correct for tilt and wind anomalies and will also supposedly calculate coefficients of aerodynamic drag and rolling resistance.

The best news, by far, though, is that all of these new features can be fully retrofitted to existing iBike Pro units. The only required upgrades are the new wireless receiver-equipped mount, which will now be available in both stem- and bar-mounted options, and a firmware update. The upgrade kit (including iBike mount, HRM strap, and speed/cadence sensor) will run existing iBike owners US$269, while new wireless units will command US$698, still a rather amazingly reasonable figure considering the feature set.

Blackburn goes wireless with Neuro

Blackburn built on the success of its Delphi

Blackburn's Delphi line of bicycle computers received a warm welcome for its exceptional ease of use, packed feature set, tidy styling, and reasonable cost. For 2008, Blackburn moves a bit further upscale with the new Neuro line, which builds on the Delphi by adding 2.4GHz wireless transmission across the range.

Naturally, the Neuro's ANT+Sport compatible signal is digitally encoded to prevent interference, and the new speed and cadence transmitters are cleanly integrated into a single unit that mounts on the non-driveside chain stay. A single head can be swapped between two sets of sensors, a feature which by itself is nothing new or spectacular, but the Neuro automatically detects which set of transmitters it is paired to and then adjusts the built-in setting (such as wheel size) accordingly. Now that's cool.

In addition to the new wireless transmission, the Neuro line also caters more specifically to the serious trainer with a five-zone heart rate monitor (Delphi models are three-zone) and a unique 'Race Mode' that displays only critical information.

Sunlight-sapping Daylight Savings is nearly over, and Blackburn has revamped its LED-based System X line of lights just in time. The biggest improvement, by far, is the new Li-ion battery which replaces last year's NiMH unit. The change in chemistry yields a pack which is just one-third the size of the original, and the new smoother shape is also easier to mount on the bike or toss into a jersey pocket. Blackburn carries over the 3W Luxeon emitters and still houses them in versatile handlebar- or helmet-mounted heads, and still utilizes the very-useful advanced Constant Current and SuperCharger technology.

New Polar CS600 computer is a coach's dream come true

The WIND calculates power

Polar's new CS400 and CS600 offer integrated solutions that combine a fully-functioned cycle computer with sophisticated HRM features. Both utilize a large-format LCD display and wireless speed and cadence sensors, along with Polar's usual panoply of training aids, including three target heart rate zones and its handy OwnZone and OwnCal features.

The top-end CS600 is also compatible with Polar's new WIND power meter, which, like its older units, calculates power output based on the speed and tension of your chain (huh? We haven't sampled it ourselves yet, but supposedly it actually works pretty well) while still allowing you to run your usual componentry. In addition, the WIND unit is now a 2.4GHz wireless widget and is far easier to install than older Polar setups.

Those features easily put Polar's new computers among the top offerings these days, but the real draw is the new software. Users can preprogram specific planned workouts on their home computer, each containing up to five intervals with varied recovery periods and repeats for each one. These workouts can then be saved in a 'personal library' that can be planned up to three weeks ahead.

The truly amazing part is that these structured efforts can then be uploaded to the CS600 unit itself, which subsequently prompts you as to what you should be doing in terms of heart rate and/or power output. Since the workouts are preprogrammed in advance and have specific dates associated with them, the CS600 even tells you what workout is planned for the day when you wake up in the morning. Workouts can be provided remotely by an athlete's coach, and the software is compatible with the ubiquitous TrainingPeaks/CyclingPeaks software for later analysis. Save for having your coach follow you around in a car with a bullhorn (or get you out of bed), this is likely the next best thing to the hands-on treatment.

Kurt Kinetic

The new Rock&Roll trainer uses a pivoting base

Fall has already arrived for those of us in the northern hemisphere, and winter isn't much further off. For the unfortunate majority, that also means that cycling will be mostly restricted to indoor use until the mercury rises to a more reasonable level. Kurt Kinetic offers up some assistance by providing its own brand of, er, resistance!

The Rock&Roll uses a wide base with a uniquely pivoting cradle that allows bikes to sway side-to-side to more closely mimic real-world conditions while also helping users refine their technique. A dual flywheel system offers 6, 12, or 18lb (2.7, 5.4, or 8.2kg) of rotational weight also delivers more realistic acceleration and coast-down feel. An optional Turn-Table front wheel support also allows the front wheel to 'steer' to further help users polish up on their balance and stability.

All of Kurt Kinetic's fluid resistance units use the company's patented magnetically coupled impeller system in which there is no shaft physically entering the fluid chamber. As there are no dynamic seals involved, the chance of leakage is virtually eliminated. Kurt Kinetic also uses a relatively thermodynamically neutral silicone-based fluid instead of more common oils in order to maintain a more consistent resistance profile as temperatures increase inside the finned housing.

Kurt Kinetic also includes its fluid resistance unit on the more conventional Pro Trainer and Road Machine trainers, while wind resistance is used for the more inexpensive Cyclone. All three are built with a stable, height-adjustable, wide-set frame that can supposedly accommodate wheel sizes ranging from 16" all the up to 29" (outside diameter).
