New Crankset - Specialised Diverge Carbon 2016

[micro553]

Hi

Looking för a new lighter crankset for my Diverge. I have the TURN Zayante by Praxis Works, BB30, 50/34T today.

I´m looking for a 52/36 in 110 Bcd that will fit. I´m not a technical guy so I don´t know witch ones will fit

FSA SL-K Light
FSA K-force
Sram Red or Red 22

The one I like the most at the moment is the K-force. Im planning on buying a used one to get it a bit cheaper. I going for 172,5 or 175 mm crank arms.

Regards

Avoid FSA at all costs, if you want decent shifting. Their rings are total garbage.

Red is good.

What group do you have on the bike?

You're not going to gain anything by going lighter on a crankset for that bike, unless you just want to blow some money. In that case, the S-Works crank is probably the lightest and potentially stiffest.

I have the 105 groupet.

Yes lighter but also longer crank arms when I have now. I have 170 now and they feel bit small.

Complete BS that FSAs latest K-Force Light BB 386 EVO is crap. It is flawless shifting and it works great! I have two sets.

Just do as manual says (and use a torque wrench) when you torque crank bolt (38-40Nm) and pedals (20-25Nm) not to low, as under 10Nm.
(Noted that my own pedals had a upper limit over 30Nm which seems extreme)
I have two of the black and grey version. This ticks both looks and great shifting, no worries about that!

I went with Red because it's inexpensive and Praxis now makes rings that fit without mods.

Yes, there seems to be nothing that beats Red when it comes to price and weight.
However FSA is certainly not a bad crankset. The chainrings are very stiff and it seems ramps and cnc work to help shifting certainly works really good.
I think FSA suffer still from the older cranks they had problems with. In a way it may be why they really set out to do something that works now.
But i still like Shimanos pre-load system the best. It is very easy to set the pre-load very light so bearings run super smooth.

If Shimano came with 30mm axle and had an option to the high polish DA crank it could be something.
It would be even better if they could get it around, or under 600 grams, complete with chainrings (no BB at this weight)

+1 on newer FSA cranks. They work very well but only if you like the graphics.

The new Red 22 GXP cranks are surprisingly light. I got a pair the other day as backup cranks and they came in at 407g without rings. With them being gxp, you can put them on nearly any bike.

wish someone (Shimano) would make it so a 24mm spindle is swappable with a 30mm one.

don't know how it could be done but would be nice. accommodating a Shimano crank into PF/BB30/OSBB is a bit annoying.

Will Red fit right on?

I can see on ebuy that the reds are pretty cheap.

Thinking of 172,5 mm and putting on a the new oval absoluteBlack rings or the Stronglight Ct2 in 52/36

So if I go with red (not red 22) will the new chainrings fit?

[micro553]

I see that the red has a red black crankset - will it fit. I´m not a technical guy so I would prefer if it fit right on without any adapters

If you want something that will work great with your 105, then spring for some DA9000 cranks. You can get them for about$370-$380 new from many places now. They are the definition of flawless shifting.

Don't overlook the Ultegra 6800 though. They are also great.

The Specialized S-works cranks are also a good option. You should be able to just switch your existing chainrings over to one. That is going to be the lightest option.

While you can mix Sram cranks into your shimano group and they will shift fine, there is really no reason to.

Again, I see zero reason to purchase something from FSA when there are outstanding affordable options from Shimano or the really great S-works crank. If you bike came with an FSA crank I wouldn't change it though. While not my favorite, they work OK. I just wouldn't seek one out.

Getting longer crank arms is a valid reason to switch cranks. You can save a bit of weight, but not a ton. Consider getting some lighter wheels for that bike somewehre down the road if you really want to drop some weight. Bars, stem, seatpost, and saddle can also end up saving you quite a bit.

About bar and seat post I´ve got enve.

Wheels i´m thinking of getting Enve SES 3.4 as I heard they are good.

Maybe just try the AbsolutBlack oval chainrings and give it some time before I make up my mind about new crankset.

My plan is to have two wheels sets - one (stock ones) for gravel with Challenge Almonzo open tubular or the gravel grinders.

And then a nice carbon wheel set for road use with Vittoria Corsa Speed TLR or Spec Turbo Cotton or Schwalbe Pro One.

And then like in a year I can get a new road frame and use the bar seat post wheel set on it with a new di group.

And keep the Diverge as a winter/autum bike.
