How To Fit An Oversized Pulley Wheel To Your Derailleur | GCN Tech Monday Maintenance

[@Hambini]

99% of people would gain more by changing the bushings (if they have them) to 699 bearings or changing the OE bearings to ones with Non contact seals. Last week, one company released an OSPW with a bearing that was so large, it had more drag than a bottom bracket. And just consider how much load goes through a bottom bracket (rider weight) vs a chain tensioning device. Ludicrous.

[@jedkoh]

Hambini, wonder if you have any 699 bearings to recommend? Mainly for wheelset usage. I reckon to go for ZZ ones rather than 2RS, am I right?

[@DeanPattrick]

Alex you’re presenter skills are super these days. Big kudos. 👍👍

[@ajrh82]

Even if you accept OSPWs do look better then surely this doesn’t apply when it has Muc off written on it. Imagine having a beautiful Dura ace or super record mech and adding something that looks like it was given away free with a magazine. Unless you see Ineos using these you can probably assume any claimed benefits are BS since they have Muc off as a sponsor and would go after the “marginal gains”

[@mynock250]

OSPW’s have mixed testing results, but Muc off is a sponsor, would it be better if it said ceramic speed on it, because all high end bike parts have logos on it wether its SRAM or Shimano etc.

[@coreygolphenee9633]

[@ajrh82]

@@mynock250 If Shimano did their own version and it was around £100 I might consider it. I would only be doing it to pimp my ride though as I ride for fun and have weight to lose before I’ll started caring about fancy bearings or weight weenie stuff or minor aero gains

No gains. Possibly losses, all things considered. Definitely loss of money.

If these oversized pulley wheels are better then why doesn't Shimanno or Sram design their derailleurs with them? Obviously the "advantages" are BS even if some people think they are cooler looking. I think they look silly.

[@iffy_too4289]

I’m going to stick with the standard Shimano pulley wheels. Since everything was engineered as a package, I think it’s risky to modify.

so shimano has just not the skills to make an oversized pulley wheel on their dura-ace? If it actually had any positive effect they would.. waste of money..

[@brankododig1585]

They could, but Shimano is persnickety about shifting quality and with an OSPW it is let's say 98% as good as a standard Dura-ace cage.

[@stephenalivero4068]

The only benefits I heard in this well done video explaining how to disassemble a rear mech and add oversized pulleys was that; the oversized pulleys are more aerodynamic and they can increase chain efficiency. So if anything this would benefit backpacking bikers. Kudos to GCN Tech

[@IraklyShanidze00X]

@@stephenalivero4068 yes, you will save 1 watt at most, provided your chain is super clean. While bikepacking, any marginal gains from the oversized pulley will be more than offset by all the stuff that you will have to attach to your bicycle.

[@chetlangford2144]

#askgcntech the 3 holes is a good tip for the rear derailleur. Some people don't know what they are used for!!!

[@brunoluong7972]

Do you wonder something is not right when a pulley wheel that has more teeth then SRAM popular 10 sprocket ?

[@kengunnett2017]

The pully wheel (upper) on my newly installed and upgrade derailleur on my trike doesn't seem to engage the chain very well in a couple of gears, it sounds like the teeth of the pully wheel are being slapped by the chain as it spins by, then you her a popping noise ever so often. My uneducated self tells me that adding a different pully wheel with another tooth or two would or might solve that problem, by forcing the wheel and chain to better engage. Might this be a common problem, my drive train is a collection of 9 speed parts from different makers.

[@matthewbaynham6286]

Can you please show the clip of Ollie riding the submarine bike.

[@matteo.ceriotti]

Oh come on Alex, you are losing all your credibility for the GCN Tech videos to come. GCN themselves have done videos explaining how this upgrade is not worth. Ok, Muc-Off is entering this market and sponsoring you, but try to maintain some integrity.

[@jochenkraus7016]

They are just showing how to install it because you might like the looks ;-) Seriously, watching all this marginal gains stuff (claimed or actual) I'm almost relieved that I'm too slow for stuff like that to matter. In older videos they demonstrate that tighter clothes or lower position gains more than changing parts of your bike that already work well.

Good video of actually how to install , but oversized pulley s are really for pro team s , most people aren't riding fast enough to need them , and the price like what ..... Most people would be better off getting a coach for a year for that sort of money and then they would really go faster

[@kibbee890]

Just add a few quick links it you dont want to replace the whole chain.

[@4shl3y38]

i have a 1×9 setup with shimano tourney rear derailleur 😂

[@matthewbaynham6286]

If the reduction in chain friction is so important why not have a chainring the size of a dinner plate, and then you can have a nice 15-25 straight through cassette or even 16-26, get those gear ratios really close as well as reduce that chain friction.

[@whunderwhoiam2489]

I guess bigger pulley - higher chances of hitting your rear derailleur ?

[@the_nondrive_side]

Just don't. Even a Acera RD-390 can handle a wider range than you need. Don't down Triple chainrings and 8 speeds.. Sold my 2020 TREK because 12 speed linear just demands triple gear jumps and doesn't have any top speed. 17-117 gear inches on my Opus kills it. Lastly.. They fail quicker when things go bad it's catastrophic. My 17t tension pulley broke and destroyed the cage it was a walk home.. I think the bearing failed. The Alivio derailleur I had went into the spokes a few time since 2013... But didn't last a week after this mod. Even a 11-13 in the stock cage did better with just sealed bearings.

Your chain pivots 180° each lap around no matter the size of your jockey wheels. So this amateur mechanical engineer needs help understanding. I do see that the bigger wheel might be heavier and have more drag. What about Campagnolo and Shimano? Do they not know how to choose the best wheel size?
