Impressive weight! Thought about upgrading my aldhu 24 to the aldhu carbon. I am moving my aldhu 24mm with the NGeco and 8100 ultegra chainrings on my Ostro vam, which has the ceramicspeed T47a 30mm BB with 24mm reducer. I noticed that the aldhu crankset sits 2mm further from the BB when compared to the stock 8100 crankset. I only put an O-ring on the drive side with no spacers. I don't think I did anything wrong and not sure if it's a must to put an O-ring on the drive side. I am also wondering if this 2mm increased chainline would cause shifting problems. I also noticed that this crankset sits 2mm further on my 2018 Scott foil. Thanks!
Make sure you follow Rotor’s recommendations for which spacers you need and also make sure to check that you have correctly tightened the preload nut. The chain line should not be an issue so long as you re-set the front derailleur limits to accommodate the one or two millimeter difference.
Thank you for this video. May I ask is this powermeter and specifically the SL version of the SL spider able to be used with other cranks, or only Rotor? Thank you so much
The SL version is compatible with a number of different crank arms, but is machined to specifically fit whichever brand you choose (Rotor, Easton, Praxis, etc.) so you'll need to select which interface you want when purchasing.
Thanks for the reply! hmm, so it sounds like this is custom-ish request to Power2Max? I am going to try to get a super lightweight Chinese crank that fits normal Power2Max, Sigeyi and XCadey power meters already. So I wonder if this SL will fit without as it already is? I will ask Power2Max directly but if you know I'd love to hear! The cranks are called Elilee by the way. @@utahcanyoncycling
The NG is the higher tier model and the Eco, while still accurate, has a few less features. You can use this with Carbon Ti rings as long as you select the correct BCD. Though, the Carbon Ti rings are not any lighter than DA chainrings.
Do you have a BB86 bottom bracket on your bike? I want to buy the NGeco SL with Dura Ace 9200 chainrings and the Rotor Carbon crank, but I'm confused on the bottom bracket and axle compatibility.
I have two bikes, one with a T47 and the other with a BB86. The rotor carbon crank arms are only compatible with a 30mm spindle. The 30mm spindle fits in the T47. If you want to keep your BB86 you will not be able to use the rotor carbon arms since a BB86 is not big enough to take a 30mm spindle without serious compromises. You can use the rotor aldhu aluminum crank arms with a 24mm spindle in your BB86 though.
@@woutervanboxstael5073 haha true true. You can do it.. but you'll need to replace those bb bearings pretty frequently. Would make for a seriously light combination though!
@@utahcanyoncycling Thank you for the feedback. I´m waiting on delivery this week but as I saw a couple of negative videos I was a bit worry. Thank you again!!
The rings might be mismatched from the crank arms, but the Shimano rings are stiffer, shift better, and have the new 44.5mm chainline. Plus the Shimano rings match the rest of my drivetrain. So not ideal from a brand perspective, but I did not want to mess round with either Shimano or Rotors inaccurate power meter. Thanks for watching!
@@utahcanyoncycling I'd think the number of spacers used on the axle and the exact measurements of the BB (as in, not per spec but on the actual bike) are the variables driving chainline. Rotor has a standard and an offset axle (for disc brake frames) with nominal 43.5mm and 46mm chainline, respectively. Where does 44.5mm come from?
@@DominikLoeffler1 I think the new Rotor chainrings for 12spd Shimano drivetrain would fit better. The chainline with them is 43,9mm. So only a 0,5mm spacer is needed on the driveside for the new Shimano chainline.
