This is the place to ask for help if you are considering a bike that comes equipped with Profile Design aerobars, or are considering adding Profile Design bars to a frame or existing bike.

In no particular order, these are the brands that spec PD (off the top of my head)
Quintana Roo - everything other than VPRi and Vision equipped VPRs
Canyon - Speedmax CF
BMC - Speedmachine and Timemachines
Scott Plasma 10
Ceepo
Argon18 E-117
Stevens Volt
Diamondback Andean
Cube Aerium C:68 Tri and TT
Parlee TTiR Disc
Wilier Turbine (orginal & SL)
Cervelo P3 and P2, P-series if you want to upgrade from stock
Sorry if I've missed any bikes

Obviously we already have assistance threads for QR, Canyon and Cervelo so you can ask there if you would rather focus on one brand.

If you would like assistance I need the following information:


Pad X is to the rear and Pad Y includes the cushion. Pad Z is the centre to centre width (or to the indents in the cushion if measuring an existing setup).
Grip Z isn't vital but is handy with some modern extensions and is the width at the base of the grip area (so that angling the grips in isn't part of the calculation)
Ext length is from the rear of the pad to the tip of the extension where the shifter inserts
Tilt is the inclination of the armrest (with the assumption that the extension will tilt too)
Add preferred grip angle and armrest if you like.

For background - I have been consulting to Profile Design for several years - first working on the Aeria Ultimate project to define the fit range. Then leading the development of the new generation brackets (Flyt series), Armrests (Ergo, Race, Boom) and Extensions (the ones with angles as names). I also founded Velogicfit (have now left) - developed 3D motion and aero capture software as well as the only bike finder that works with Pad XY.
