No problem
"No problem"
Fast delivery and attractive special offer
"Fast delivery and interesting promo".
Good quality crankset
"It's easy to put on, but it would be better if it were a little more fluid, it's amortized this box in profitability"
true to the original.
"Perfect, nothing else to say except that with the right tools it's very easy to take it off and put it back on."
In place of the 105
"Bought to replace a Shimano 105 gearbox. Dura-Ace is lighter. Bearings are smooth. The cups are plastic, which I prefer on a carbon frame. The gearbox comes pre-greased. Still, I preferred to add marine grease to the bottom bracket axle and sleeve seals."
super box
"super box and no cracking and very fluid and easy to assemble provided you have the right gear".

"Bonjour, trés bon produit ,c'est du shimano Dura Ace ."
Difficulties mounting on my bike
"Attention, I own a 2014 Lapierre Sensium bike mounted in Pressfit 41mm diameter and 86. 5 mm (diameter of the bottom bracket axle 24 mm) I had huge difficulties to mount this box in my frame with the proper tools even though it is a standard external diameter (41 mm) I had a Shimano Ultegra SM BB72 (original and therefore 7 years old) and I was tempted by this model Dura Ace SM BB92. ... Now the bottom bracket is mounted correctly, I don't seem to have any cracking noises when pedaling, but if, like me, you have an original SM BB72 on your bike, stick with the Shimano 105/Ultegra bottom bracket and don't switch to this Dura Ace model which, although it has the right dimensions (because it's standardized), presents incomprehensible difficulties when mounting".

"Good product easy assembly using two large washers and a threaded rod, I used it with a triple ultégra."
