Extralite UltraPulley (vs Dura-Ace) time to shed some grams! 🥴

- Instead of adding weight with ugly OSPW, we can actually make the rear derailleur lighter. One option is the Extralite UltraPulley, a bonus it's not made of metal so no risk of added noise either!

I've owned these on multiple derailleurs and they are trash. The Extralite pullies bearings wear out super fast and will cause more drag than the factory ones.
Well, here we are in 2024, about 100 years after Tulio Campagnolo invented the rear derailleur and the jockey wheels are now bigger than the smallest cog on the rear cassette.
😁
Love your attention to detail, and thanks for the note about adjusting for the different thickness.
Does anyone else say HELLO to thier scales when they start up, or is it just me?
Hey just my 2 cents:
Great weight and silent operation BUT:
1.The 4 ceramic bearings on those pullys are really fragile. Very VERY carefull on tightening them.
2.The second pulley hanging on the derailleur is very sentive to side load SO, carefull of putting the chain back on the bike when installing or after dropping it and extreme cross chaining.
3.The derailleur tweaking to acomodate these pulleys sticks out more make it less aero and more prone to scratches and\or crashes.
Cheers for the comment! Always good to stock up on reports from real users! 👍
Just a word of warning, the cage of that derailleur is carbon, point being that it breaks easily and the half that broke on my 9150 RD was $150 and I had to wait almost 3 months to get it from my local bike shop. You spread that cage wider and your chain is going to jump over the tab that keeps it tracking on the wheel and then the chain will rip the cage apart. Those pulley wheels are not something I would put on my bike. Especially wouldn't take the risk to save a couple of grams.
the real argument against OSPWs are that by now, both SRAM and Shimano refreshed their top-of-the-line ultra performance Groupsets (Red/Dura Ace) and they could've added OSPWs, but they didnt. So the "gains" of OSPWs are negligible, and they just look different.
There is 1 benefit in these wheels that no one talks of. Noise. I have a similar set, and they are noticeably quieter than stock shimano. For that, it is worth it, but no other reason makes sense to me.
That's an insane amount to spend on pulley and screws. If you weren't so OCD about weight and cleanliness, I'd say the extra dirt that will collect inside the 'spokes' of the pulley wheels will negate any weight savings
Yeah, Aint no dirt touching my shit! ;)
I'm conflicted about OSPWs and Shimano standard pulley wheels. I wish Shimano's were bigger, better, and lighter. And freer rotating! I don't like the look of e.g. CeramicSpeed OSPWs, and the price is frankly ridiculous, but that said, I am considering one for my next bike... (maybe I shouldn't be watching weight weenie videos because if I had any credibility whatsoever in that department, I just lost it!). The main reason is bearings, and I'd prefer - slightly - larger pulley wheels like in this vid. I was feeling encouraged by the vid until the derailleur adjustment. I don't really want to mess with derailleur limits or indexing if I can get away with it! I prefer to leave Di2 be post setup and let it do its thing which is generally flawless in my experience. Peace!
Do you need to lengthen the chain?
I didn’t. But if you on the absolute edge of what the standard mech is capable of you might have to. But If you have followed big+big method that Shimano recommends I think you can get away with not lengthen the chain.
Once you adjust the b-gap it should be pretty clear if you need to do anything.
Edit: ops, wrong account 😅
Are bearings on the new wheels sealed? Did you increase the length of a chain?
Yes (how good I can’t say) and no, same length chain.
They are sealed but they are also very thin and fragile. Same length the added size on the pulleys is negligible. My advice? Don´t buy these unless you are a indoor cyclist!
Thank you both 🙏
Weightweenism is progressing again😊
I wonder why shimano changed to bearings on their high end derailleurs. Old dura ace is just ceramic bushings. Probably lighter than steel bearings and no maintenance, ever.
Which generation did they change that? Always thought the DA had bearings (in modern times that is)
@@slayerofgrams Sorry about that, I think you're right. Ceramic must have only been up to Ultegra then? R2 has the weights for Y5X998150 which is one bearing one bushing. The pair is 19g. Not hollowed out, no screws, 11t. A set of 6800 replacement pulleys (Y5YC98140) is 21.3g. Two bearings, hollowed out, also 11t. I'm pretty sure my 6600 Ultegra derailleur had upper and lower ceramic bushings though. According to ceramicspeed there's a 0.5w difference per bushing in favor of bearings. Not sure how long bearings keep up that advantage. I guess they tested them brand new. Does the upper pulley on those modern Shimano derailleurs still have lateral float to correct small misalignments or is that a thing of the past?
@@hmartinlb My latest Di2 DA has no float. This might be because it's di2 though. The Mechnical might still have the float... haven't had mechanical since before 2011 😅
Oversize pulley wheels = overweight pulley wheels
