Hope 13T Jockey Wheels Review: 13 Tooth Shimano 12-Speed Fit
This Hope 13T jockey wheels review is mostly about compatibility. The Hope 13 Tooth Jockey Wheels are not a universal derailleur upgrade. They are a specific replacement pair for riders using compatible Shimano 12-speed derailleurs, and the whole purchase depends on tooth count, pulley position, rotation direction, and cage clearance.
If your current jockey wheels are worn, gritty, noisy, or full of play, the Hope set can be a smart premium replacement. If your existing pulleys are still fresh and you are expecting a dramatic shifting transformation, this is the kind of upgrade that needs a reality check.
Quick Verdict
The Hope 13 Tooth Jockey Wheels make the most sense as a high-quality replacement for compatible Shimano 12-speed rear derailleurs. The appeal is the CNC-machined aluminium body, stainless cartridge bearings, low-friction seals, labyrinth spacers, and Hope’s usual color options.
They are not a good blind upgrade for every derailleur. Before buying Hope jockey wheels, count the teeth on your existing upper and lower pulleys, check the Hope compatibility chart, and make sure the 13T/13T setup matches your derailleur. If your derailleur does not use 13T upper and 13T lower wheels, do not force it.
Fast Compatibility Answer

|---|---|
| Most likely fit | Compatible Shimano 12-speed MTB derailleurs, after confirming the exact model and pulley tooth count. |
| Do not guess on | SRAM Eagle, SRAM Transmission, Shimano road, GRX, CUES, or older Shimano 10/11-speed setups. |
| Main benefit | Fresh bearings, better sealing, durable CNC aluminium pulleys, and a cleaner replacement for worn jockey wheels. |
| Main warning | They will not fix a bent hanger, worn chain, poor indexing, or the wrong pulley tooth count. |
Hope 13T Jockey Wheels Key Specs
Hope lists the 13 Tooth Jockey Wheels as suitable for Shimano 12-speed derailleurs and aimed at riders looking for a lightweight, durable pulley-wheel set with reduced drivetrain drag.
| Product type | Rear derailleur jockey wheel pair |

The important words are 13 tooth upper and 13 tooth lower. Tooth count is not decoration. It affects cage clearance, chain path, shifting, and whether the pulley wheel belongs in that derailleur at all.
Compatibility: Do Not Guess
Hope’s jockey wheel compatibility chart is worth checking before you buy. It says to match the rotation arrow with the direction of the chain while pedalling forward, expect that fine indexing adjustment may be needed, and always count the teeth on your existing jockey wheels before swapping like for like.
That last instruction matters. Many derailleurs use different tooth counts between upper and lower pulleys. Some use 11/13, 12/12, 13/13, 12/14, 14/16, or other combinations depending on brand and drivetrain. A 13T Hope pair is right only when the derailleur calls for that setup.
If your bike has Shimano 12-speed MTB, these are in the correct family. If you are running SRAM Eagle, SRAM Transmission, Shimano road, GRX, CUES, or older Shimano 10/11-speed, check the chart carefully instead of assuming the Hope 13T pair will fit.
Upper Vs Lower Pulley
Rear derailleur pulleys are not always interchangeable. The upper guide pulley controls chain position near the cassette. The lower tension pulley manages chain wrap and tension. Some pulley sets have direction arrows, offset spacers, or different shapes for top and bottom positions.
On the Hope 13T set, install them according to the supplied instructions and rotation markings. If shifting feels slightly off after installation, that does not automatically mean the wheels are bad. Hope’s chart notes that fine indexing adjustment may be required after fitting new jockey wheels.
Bearings And Seals
The main technical reason to buy the Hope set is not that aluminium pulleys magically make a drivetrain faster. It is the bearing and sealing package. Hope uses stainless steel cartridge bearings with low-friction seals, and labyrinth-style spacers that help protect the bearings from dirt and reduce maintenance.
That matters because jockey wheels live in a filthy place. They sit low on the bike, close to chain lube, grit, mud, degreaser, and wash water. A worn pulley can develop play, spin roughly, or collect grime around the teeth. In a bikewrench discussion about jockey-wheel bearings, riders focus on tooth count and bearing condition rather than treating pulley wheels as a universal performance upgrade. That is the right mindset here.
Will They Improve Shifting?
They can help if your current jockey wheels are worn, loose, gritty, or damaged. Fresh, correctly sized pulleys with healthy bearings can make the drivetrain feel cleaner and quieter.
But if your stock jockey wheels are in good condition, do not expect a dramatic shift-quality upgrade just because the pulley wheels are aluminium. In a discussion about changing plastic jockey wheels to larger alloy ones, riders warned that the difference may be small if the originals are healthy, and that fit is the bigger question. That is a fair warning.
The Hope set is best thought of as a premium replacement and durability upgrade, not a secret drivetrain horsepower trick.
When They Are Worth It
The Hope 13T jockey wheels make sense if:
- Your derailleur is compatible with a 13T upper and 13T lower setup.
- Your original pulleys are worn, noisy, gritty, or loose.
- You ride in wet or gritty conditions and care about sealed cartridge bearings.
- You want a serviceable-feeling premium replacement rather than basic plastic pulleys.
- You care about matching Hope finishing colors without ignoring fit.
They are also a nice detail on a well-maintained bike where the drivetrain is already clean, adjusted, and using a healthy chain and cassette.
When To Skip Them
Skip them if your derailleur does not use 13T upper and lower pulleys. Also skip them if you are trying to fix shifting problems caused by a worn chain, bent hanger, dirty cable, bad B-tension setup, worn cassette, or poor indexing. Jockey wheels will not solve those issues by themselves.
In a rider thread about aftermarket pulleys, the practical reasons people mention are replacement quality, tighter fit, color, and bearing quality. That is a grounded way to think about the Hope set. Buy them because they are a good compatible replacement, not because you expect miracles.
Install Notes
A careful install should include:
- Take a photo of the derailleur cage before disassembly.
- Count the teeth on the existing upper and lower pulleys.
- Check any rotation arrow on the new pulley wheels.
- Keep track of spacers, washers, and pulley bolts.
- Clean the cage plates before reinstalling.
- Torque the pulley bolts to the derailleur maker’s specification.
- Check shifting and make fine indexing adjustments if needed.
Do not over-tighten pulley bolts or leave threadlocker residue where it can bind the pulley. The wheel should spin freely when installed, with no cage rub and no side-loaded bearing feel.
FAQ
Are Hope 13 Tooth Jockey Wheels compatible with SRAM Eagle?
Do not assume so. Hope lists this 13T set as suitable for Shimano 12-speed derailleurs, and its compatibility chart separates different SRAM and Shimano setups. Check the chart and count your existing pulleys before buying.
Will these fit Shimano 12-speed MTB derailleurs?
Yes, Hope lists the 13T jockey wheels as suitable for Shimano 12-speed derailleurs. Still check the exact derailleur and existing pulley tooth count before installation.
Do jockey wheels have to match tooth count?
Yes. Hope’s compatibility chart says to count the teeth on your existing jockey wheels and swap like for like. Tooth count affects cage clearance and drivetrain behavior.
Will aluminium jockey wheels shift better than plastic ones?
Not automatically. If your current pulleys are worn or gritty, fresh Hope wheels can improve feel. If your stock pulleys are healthy, the improvement may be mostly durability, bearing quality, and appearance.
Do these need indexing after installation?
They may. Hope’s chart notes that fine gear-indexing adjustment can be required after installing new jockey wheels.
Are the bearings serviceable?
Hope uses stainless steel cartridge bearings with seals and protective spacers. If the wheels stop spinning smoothly after heavy use, inspect and service or replace the bearings according to the part condition and Hope guidance.
Bottom Line
The Hope 13 Tooth Jockey Wheels are a good premium replacement for the right Shimano 12-speed derailleur. The best reasons to buy them are bearing quality, sealing, durability, clean machining, and color choice.
The wrong reason is thinking they are universal or that they will fix every shifting problem. Count the teeth, check the compatibility chart, install them in the correct position, and treat them as a precise drivetrain replacement rather than a decorative shortcut.
