  • HollowGlide hollow outer chainring gives vast improvements in rigidity by virtually removing outer chainring flex and hugely improves shift performance, even under high load
  • The chainring teeth have been developed to work in conjunction with the CN7900 and CN6700 chains for increased contact to provide greater efficiency and improved power transfer
  • Industry leading HollowTech II cold forged hollow crank arms have been evolved to increase rigidity, reduce weight and improve strength
  • HollowTech II integrated bottom bracket uses a wider bearing placement and larger axle diameter for increased stiffness and efficiency (not included)
  • Weight - 785g

Rated 4.8 out of 5 by 4 reviewers.
Rated 5 out of 5 by Great piece of kit I bought this chainset to replace the stock Oval/FSA compact chainset on my Fuji Altamira. I was concerned that it wouldn't match up with the FSA BB86 that was on the bike but fitting it was a doddle and a quick measurement with an electronic vernier confirmed that both shafts were identical in size. Gear changes seem smoother and I'm very happy with how it looks on the bike. I got my LBS to torque the bolts for me when getting the bike serviced. 19 August 2013
Rated 5 out of 5 by 1-2 Extra Gears At 45 y/o and 90KG with knees creaking as I grind up climbs, I finally conceded it was time to ‘go compact’. This compact set does not give you a MTB granny gear capability. However, it does give you 1-2 extra gears for climbing. I now spend significantly more time in the saddle on climbs. I have definitely had an increase in cardio/respiratory output due to the higher cadence when climbing; this took a few decent long climbs to adjust to. This is a man’s answer to a ‘triple’! 22 June 2013
Rated 4 out of 5 by Light, strong, good lookin and easy on the legs ;) 11 April 2013
Rated 5 out of 5 by Light and looks great Just upgraded to this chainset from my 105 double. Switching to compact was great for me as my desire to climb hills was not matched by my ability!!! Looks great on the bike, is lighter and shifts well when compared to the 105 double. 07 May 2012

Answer: 
This crankset in conjunction will give a lowest gear ratio of 1.2 which should be adequate for climbing most hills.

Answer: 
The choice of crank length is purely down to rider preference.

Some say the taller the rider the longer the crank arm but there are no hard and fast rules or reasons behind this.

Answers

Answer: 
Due to the narrower teeth on a 10-speed chainring; it will eat into a 9-speed chain (which is essential for shifting on the 9-speed cassette) at a much higher rate than normal.

This combination of drivetrain speeds is not recommended due to reduced shifting efficiency and component longevity.

Answer: 
Yes, you can replace a 10 sp FSA Gossamer (campagnolo) with this ultegra 6750 (10sp) but you will need to buy a Shimano Ultegra 6700-6703 Bottom Bracket as well.

Answer: 
These components combined are compatible; the weight difference is minimal but the Dura Ace 7900 bottom bracket sports higher quality seals and smoother bearings.
