With the arrival of the 11v Shimano presented the Dura ace

lighter (-15g) and more resistant! Just that! Concerning the lifespan
we will see that in time but for the performance/operation part!
I wanted to know more by opposing it
to the DA 10V.
and prepared with Squirt lube just before the tests. The DA 10 V test has about a
hundred Km and the DA 11 V has just been broken in. Indeed to obtain the
best performance from a chain! it is already advisable to remove The 2 chains the original lubricant
(1 to 2 watts lost otherwise) and especially to do a break-in over 30 km to finish deburring and perfect the friction between the links as recommended by
Friction Fact:
In terms of feel and operation! I noticed no
difference! the 11v works perfectly on a 10V cassette and a
SRAM red derailleur! It is perhaps even better on a
100% Shimano 11V group. In terms of measurements! we note a very The 2 chains small
difference and a gain that would be favorable to the 11V. This would be 0.5 to 0.8
watts…
Very close results
Once again! we are in the realm of the tiny and certainly without possible conclusion due to the precision of the protocol (< 1%) and the small difference. To validate my study! I
once again turned to Friction fact and I directly asked
Jason Smith the question to know if he had a lot of perspective on the 11V. Indeed according to him the 11v is as good
as the 10V. However! he notes through the dozens of country email list tests that he has already been able
to do that the 10 V would be better by 0.25 w average to 250 w. He specifies!
however! that from one chain to another and therefore from one manufacturing series to another
! there are dispersions in the yield and that an 11V can be lead generation blog essential strategies slightly superior to a 10 V.
He obtained up to 0.5 watts in favor
of the 11v but it is also true in the other direction with 10v going up to 0.75
watts better than certain 11v…
The Friction Fact selection
In short! this test concludes that Shimano 11V chains are as good as the 10V ones! we could have had a doubt given the fineness of this last model. It remains to validate the lifespan
in the face of elongation and the barrier of 0.75/1mm. For the moment the DA
7900 V are really great with often 5000 km achieved without malaysia numbers list problems as long as we
take care of them.
