Hi Dev,


That, and the priorities are different between the R-series and P-series. More emphasis on aero for the P-series, so the smaller bearing reduces the frontal area of the head tube.

Cheers,

On the new P3 I feel like I am on a highly upgraded version of my original white Kestrel 4000. I saw a picture of Mark Allen riding it in Nice in 1990 and was first on the local buyer list in 1991. Carbon bikes have come a long way, but that thing had a narrow head tube:



Unfortunately, mine developed a crack so I got a Kestrel 200 SCi a few months before Penticton 1991. Also very narrow frontal on that bike...that was IM number 1....thanks for getting me to the start of IM #26. Everything is mechanically good to go. After being cooped up in airplanes and hotels for 2 days with mechanical and rain related forced taper just went did 40K of riding with 2000 ft of climbing and everything is rock solid now:

Hi Dev,

It's a small world - I worked for Kestrel as a tech rep from roughly 1989-1991. :-)

Thanks for the photos and a trip down memory lane!

Cheers,

6 speed
Mavic GP4 rims
Down tube Dura Ace Shifters
53x39 with 13-18 corn cob (wtf was I thinking doing IMC on that?)

Profile Clip ons

Kestrel 200 SCI frame


I still have that bike bolted to my computrainer upgraded to 8 speed with profile base bars and visiontech clip ons and 13-23 cassette and 170 Sinz taper square 110 bcd BMX cranks. I believe taper square BB was replaced around 3 times. Kestrel gave me a warranty upgrade to the frame in 2000 as it had developed a crack by then.

Sorry to revive an old thread but I took my 2014 P3 apart to clean the headset and found that the bearings were seized to the frame and they basically disintegrated while I was taking them out. I went to my LBS but they apparently ordered the wrong size (41.8 mm) as they will not fit in the frame. I've found what I believe to the be correct part number from Cane Creek (HSS20130) but I was wondering if anyone can confirm that both the top and bottom bearings are the same before I order.
