stompandgo's Pinarello Nytro E5 Allroad build thread

[Stefan Mikes]

I know you're expecting Jeremy, but I stopped by to make sure you're safe -- here you are posting while under attack.

Still all fine...

Wow, that 9-45 cassette looks really nice and about 100g lighter than the 11speed XT.

Does TQ support the Auto Shift or the Free Shift features that Shimano lists with the 8260? That would certainly add to the argument for the long cage hardwired one.

I'm not sure. The 8260 connects through the TQ Smartbox and Shimano CAN adapter. I saw no configuration options in the service tool other than turning e-shift on. The hardware and motor interface is there, it would be up to software/firmware. Once things calm down, I'll call US TQ (QBP) and ask. Great question. I can't see myself using auto shift but definitely free shift.

I apologise for my ignorance: I've always thought the long cage derailleur was meant to accommodate a huge cassette with a big teeth capacity. In what sense the long cage derailleur cannot be used with a smaller cassette?

I cannot fail noticing your Nytro has a pretty long stem: Isn't is a design option to provide proper Reach?


I know Jeremy you don't expect the answer from me but from Chris As the Nytro Allroad is based on the Grevil (gravel) frame and has gravel bike tyres, it is just an "equipped" flat handlebar gravel e-bike (you can ride a gravel bike on almost anything except mountain technical singletracks).

The long cage derailleur can be used, but shifting could be compromised. Also, the 9-45 cassette is marked twice on the Shimano compatibility chart as "not for E-Bike". I don't know why. The last thing I want to do is get Di2 and have it not shift like Di2. I'll see if I can ask Shimano why the restriction exists.

The stem length is more gravel oriented than MTB.

Unless it's just my internet acting up (always possibility) I don't think the photos of your lovely bike have transferred over.

...but I'm hoping that the range will be long enough to minimize riding with the assist off.

Is this because of a health issue? If not, riding a 30lbs bike unassisted is very different then riding your older 62lbs bike unassisted. The Pinarello should ride beautifully on the flat at that weight unassisted, enabling your range to be a lot further, saving battery for hills, headwinds and that last weary few miles home.

I'll second that. I often do rolling coast rides averaging 12 mph and ~30 ft/mi of climbing with my 38 lb Vado SL 1 in OFF.

Typical ramp-and-flat Coast Highway topography with elevation gains of 60-100 ft each time up. Not quite as steep as it looks in this telephoto shot.

But I have the time and the 22-99 gear-inch drivetrain to do it. Adding assist just adds speed and fun. Also typically ups workout intensity via the Carrot Effect.

Safe bet that @stompandgo is a stronger rider than I am.

You live on the bleeding edge, you die on the bleeding edge. Well, not exactly die, you just don't get to ride when you want to.

Some of the upgrades for the Pinarello.

Shimano WH-RX880 32mm carbon gravel wheels
Shimano CS-M8200-12 12 speed 9-45 cassette and TL-021 lockring tool
Shimano M8250 wireless Di2 upgrade kit (the switch is on the bars}

The wheels were in the shop, take-offs with the HG Spline 2 12 speed HG freehub on them. The boss ordered me the Microspline freehub that's needed for the M8200 cassette. It's not a difficult swap, although everything has to be done just right. I did the swap the first time and it looked and spun fine. When I put the cassette on, though, the freehub was binding. I tried it in the frame, and it was worse. I then removed the freehub and reinstalled it two more times, just in case. Same result. So I called Shimano dealer support. In less than a minute, the problem was identified.

These wheels have cup and cone bearings with press-on end caps. The problem is that the end cap is interfering with the 9T cog. Shimano has a redesigned end cap for these wheels in the design stage, but it will be a few weeks before they are available. I've got one with my name on it coming ASAP.

So it seems, like in any other business, the various departments aren't talking to each other. The cassette group designed this great cassette specifically for enduro MTB's that care about weight and clearance. They had a tool designed for it as well. The derailleur group saw the opportunity to create a mid cage derailleur in order to optimize shifting and clearance. Somehow, the wheels group did not get invited to the party. That's my theory and I'm sticking to it.

Meanwhile, I've been mounting up the 45mm Gravel King tires and Tupolito TPU tubes, and the Zipp rotors from the OEM Shimano RS wheels. I've got the cockpit set up loosely, and will be working on the brakes next. I've figured out a way to mount my Varia to the end of the rack. I picked up a carbon Cane Creek eeSilk suspension seatpost during their 40% off sale. I'll start riding it with the ISM that's on the Cannondale.

Glad you're getting it sorted out. Do you think the incompatibility is just from the HG 2 > microspline conversion or would RX880 wheels that ship as microspline also have issues?

Seems like a pretty big oversight, though I guess GRX has always been sort of the red haired step child of the road and mtb lineups.

 

[stompandgo]

The Shimano tech said that it is this wheel and cassette combination that has the issue, not the conversion. We shall see.

I didn't want to go GRX because of no Di2. Shimano should have made my upgrade kit and cassette GRX Di2. Another marketing vertical for the same product.

What Shimano should do is make Microspline the standard across road, MTB, and gravel going forward. It's a superior freehub design than anything else they have.

Bike techology's gotten so cool in the last 20 years. I envy your up-close first-hand experience with it.

It has, but it's lost its beauty.

You should hang around your friend's shop for a bit.
