36 rear hub road bike possible

Currently own this bike: https://99spokes.com/en-EU/bikes/cube/2021/nuroad-pro

Tiagra 10 speed, 11-34 cassette, 12x142 axle with disk brakes. 28 spoke wheels.

I would like to make my (next) rear wheel stronger. Is there a 36 hole rear hub available or the max I can go is 32 hole?

Myriads of 36 hole hubs.

I imagine a google search would come up with some.

Have to ask, are you having any problems with the current wheel and how much do you weigh? Many 32h setups are very strong and may be all you need.

Unfortunately, while current (4700-series) Tiagra has 36h hubs in rim brake versions, it looks like the current Tiagra line tops out at 32h for front/rear disk.

https://bike.shimano.com/en-EU/produ...agra-4700.html

If staying within the same groupset is important to you with your hubs, 32h may indeed be the most you can do.

The Shimano RS770 hubs appear to be available in 36h/142x12/centerlock disc configuration. But they're a bit pricey.

https://bike.shimano.com/en-EU/produ.../HB-RS770.html
https://bike.shimano.com/en-EU/produ.../FH-RS770.html


Edited to add: the R7070 also appears to be available in 36h/142x12/centerlock disc configuration. It seems a bit more reasonable than the RS770, but still far more than the 4700 series hubs.

https://bike.shimano.com/en-EU/produ.../FH-R7070.html
https://bike.shimano.com/en-EU/produ.../HB-R7070.html


Other hubs may be available in 36h/142x12/disc brake configuration from other manufacturers, and other Shimano hubs may also be available in 36h/142x12/centerlock disc versions. Haven't researched the issue in detail; dunno.

The OP is looking for 36h/142mm thru-axle disc brake hubs. Of the ones at the link above, the RS770 and R7070 are the only ones of that type. The rest appear to be either rim brake or QR disc.

What is the current issue with your wheels?

I am a big person with a lot of extra to love and pretty much all of my wheels are handbuilt 32h wheels. I wouldn't worry too much about 36h unless maybe for a touring bike or maybe a heavy use mountain bike. Talk to your local wheel builder or a wheel builder not in your area who is well regarded and see what they suggest.

Sorry, forgot to mention in the first post, I am using my bike for touring, carrying up to 25+ kg of weight plus me being a big person ads up on wheel.

I guess I will try 32 hole when the time comes, so to keep it within reasonable cost.

36 and even 40-hole rear hubs are out there, so I say do it, even if it means giving money to a different hub brand. I'm not an exceptionally big person (by American standards anyway), and I still plan to build 32-spoke rear wheels for the foreseeable future.

Personally I would rather have a good 36 hole build for peace of mind since you say you're a big person, I'm guessing that means well over 100kg plus the 25kg of gear. Have you taken a loaded test ride with your bike yet? I ask because it looks like it was made to be a lightweight speedster which may be a handful to ride loaded. Best to try it out first before buying a new wheel.

That's not quite the bike I'd want for carrying 55lbs of added weight up hills. For daily riding unloaded it looks great.

If you want really strong wheels, there are all kinds of tandem wheels with 40,44 or 48 spoke in various axle widths. Or go crazy with low-rider 144 spoke wheels but those are usually on 1 speed hubs.

I put 36s on my touring bike. I never want to be stuck in the middle of nowhere with a broken bike. Bike & gear weight over 100 pounds when I rode across the USA. Never had any spoke/rim issues. Between mailing extra gear home and me losing fat, the weight on the wheels decreased as I went east. There isn't any extra bike weight in going with 36s vs 32s when you carry spares for the 32s and the tools to change out a broken spoke.

More important is the brand and weight of rim. At our local bike coop I see many Asian made rims that have pulled apart at the spoke holes due to too-few spokes with higher spoke tension. The fad of cheap boutique race wheels sure needs to be avoided on touring bikes. Its hard to beat a standard 36 wire spoke wheel for reliability.

A 36h wheel is not going to really change the cost by much aside from 4 more spokes and nipples per wheel but get the right wheel for the job and don't skimp out on it if you are worried, a good handbuilt wheel with quality parts is going to last a long time. Look at it in long term costs. A set of say White Industries hubs, Velocity Rims and Sapim or DT Swiss Spokes and nipples may seem expensive if purely looking at initial cost but if I have that wheel set for 10-20-30 years and I rarely have to deal with it or worry about things coming loose that is money well spent but if I go for something cheap just because it has a spoke count and I have to keep truing and or replacing spokes or replacing wheels that is not worth it for me.

So I looked at the link and everything I saw indicates that your bike has quick release axles, not a thru axle. I also counted the spokes and came up with 32. Did you link to your exact bike?

No, it has 28 spokes, and a thru axle.

My wheels already have custom DT Swiss Alpine 3 spokes (with a standard rim and hub that came with a bike), and I dont use this bike for heavy touring. 100kg rider + 25kg of weight is reasonable.

Still, I think I will go for more spokes for my next rear wheel.

Thru axle limits choices for 36 hole hubs, but Velocity has a convertible hub available in 32, 36 and 40. https://www.velocityusa.com/product/...-disc-rear-hub

Velo Orange has disc and non disk hubs with 32/36 holes. they are high flange for a stronger wheel build. I recently purchased ebikes for me and the wife. The manufacture used 13ga spokes and budget rims. I new this before purchase. I have Ryde Andra 40 rims ordered. These are the strongest rims made. Ryde makes high quality reasonably priced rims.
