Logitech G25

Overview

Despite the article title reading "Logitech G25," the product covered here is the Y30088 — a third-party mounting clamp used to secure Logitech G-series racing wheels to a desk or rig. It is not the wheel itself.

The part is molded from ABS, weighs 100 g, and measures 13×10.49×3.51 cm, which places it squarely in the replacement-hardware category.

The short version: this makes sense if you bought a used G25 or G27 without its clamp, if you cracked your original clamp, or if the stock clamp simply does not fit your desk or rig. On Amazon.co.jp it was listed at ¥3,118 as of 8 June 2026, with a 4.3 out of 5 rating across 19 reviews (86% positive, same capture date).

A few thousand yen to stop a wheel from sliding around is reasonable value.

If your original clamp is intact and working, you do not need this. A plastic clamp is not a magic upgrade that grips harder than stock — it restores stock-level mounting in situations where the stock part cannot be used.

Compatibility Guide

Listed compatibility covers Logitech G25, G27, G29, G920, G923, and Driving Force GT. Logitech's desk-mount wheels share a similar clamping design across generations, so a single part covering six models is plausible.

Still, "on the list" does not mean "guaranteed on your desk." Check these four things first.

• Desk or frame thickness. The 3.51 cm figure is the part's overall depth, not the maximum clamping thickness, which will be smaller. Thick tabletops or desks with a support rail underneath are the usual failure cases. Confirm the current figure on the product page.
• Wheel generation. The G25/G27 base differs slightly from the G29/G920/G923 base in shape and hole placement. Compare a photo of your own wheel's mounting area against the product images before ordering.
• Rig frame profile. Square aluminum extrusion and steel tube do not present a flat tabletop-like surface, so a clamp designed for desks may not seat properly. Dedicated wheel stands with a mounting plate are a better match.
• Other brands will not work. Thrustmaster, Fanatec, and MOZA wheels use different mounting hardware. This is a Logitech-specific part.

This clamp also does nothing for pedal movement. Sliding pedals need a non-slip mat or a pedal plate instead.

Installation and Mounting Tips

Fitting is tool-free — the clamp attaches to the wheel's existing mounting mechanism and takes a few minutes.

1. Unplug the wheel's USB and power leads and clear the desk edge.

2. Pick a clamping position away from drawer rails, chamfered edges, and cable trays.

3. Attach the clamp to the wheel base and snug it lightly against the desk.

4. Turn the wheel lock to lock, check for lift, then tighten fully.

The key rule is not to overtighten. ABS is light and easy to mold but far less forgiving than metal; over-torquing cracks the tabs and threaded sections.

Stop when resistance builds, and if the wheel still shifts, slip a thin rubber or felt pad between the clamp and the desk. Extra friction buys you grip without extra torque, and it protects the finish.

Also worth noting: wobble under force feedback is often the desk moving, not the clamp slipping. If retightening does not help, check the desk legs first.

Product Info

Price on Amazon.co.jp (ASIN B0F1F4W5DM) was ¥3,118 as of 8 June 2026.

Prices move often with sales and stock, so check the listing for the current figure before buying.

Ratings stood at 4.3 out of 5 from 19 reviews as of 8 June 2026 (86% positive).

That is a decent score for replacement hardware, but 19 reviews is a small sample — one bad batch or one incompatible desk swings the average noticeably. Read whether the low reviews say "it broke" or "it didn't fit my desk"; that distinction matters more than the star count.

Figures captured from other sales channels are not used in this article; the reason is in the cautions below. Warranty follows the seller's own terms, which for third-party accessories is typically short.

The product is listed as released in March 2025.

Alternatives Compared

A clamp is only one way to stop a wheel from moving.

The rule of thumb: keep the current wheel on the current desk, buy a clamp; get off the desk entirely, buy a stand; plan to move to direct drive, skip the clamp and save toward a rig. Direct-drive bases produce far more torque than G-series wheels and are not designed to be held by a plastic desk clamp.

Best Use Cases

• You bought a used G25/G27/G29/G920/G923 with no clamp. The most straightforward case — a few thousand yen restores a complete setup.
• You cracked your original clamp. ABS mounting parts fail from age and over-tightening; the wheel itself usually outlives them.
• The stock clamp does not fit your desk or budget rig. Verify the frame profile first, since a compatible part can miss for the same reason the original did.
• You want a spare set of mounting hardware. At 100 g it is easy to keep a second one for a portable setup.

Skip it if your stock clamp works fine, if you are moving to a direct-drive base, or if the real problem is a wobbly desk.

Things to Check Before Buying

1. The listing title and the actual product may not match. This article is titled "Logitech G25," but every collected spec — weight, dimensions, material — describes a clamp, not a wheel.

Storefronts sometimes register accessories under a wheel's model name, or mix accessory data into a wheel's page. Before ordering, compare the product images, title, and ASIN (B0F1F4W5DM) and confirm whether you are buying a wheel or a mounting clamp. Getting this wrong means a plastic part arrives when you expected a wheel, or vice versa.

2. Watch for inconsistent prices. The Amazon.co.jp figure of ¥3,118 is sensible for a plastic clamp, but other channels showed amounts an order of magnitude higher — almost certainly used wheel listings caught by the same "Logitech G25" search term.

Those figures are not used here. When comparing shops, confirm each listing is for the clamp alone, not a complete wheel.

3. It is not stronger than stock. An ABS clamp has limits.

It targets the gear- and belt-driven G25/G27/G29/G920/G923 class and will not hold a high-torque direct-drive base. Do not expect metal-rig rigidity when you hit a kerb.

4. An awkward desk edge will defeat it. Thick tops, rounded edges, glass tops, and modesty panels or drawer rails near the edge all cause problems — glass in particular can crack under clamping pressure.

Measure your desk thickness and the flat area within 5 cm of the edge beforehand.

5. Overtightening is the most common failure. Tightening harder every time the wheel shifts eventually snaps the plastic.

Add friction material or stabilize the desk instead.

6. Small review sample, recent release. Nineteen reviews at 4.3/5 (captured 8 June 2026) is not enough to judge long-term durability.

Treat it as a low-cost fix rather than a lifetime part.

FAQ

Q. Is this the wheel itself? A.

No. It is a clamp for mounting the wheel to a desk or rig.

The 100 g weight and ABS construction are the clamp's specs, not a wheel's. Check the product images before ordering.

Q. Does it fit G29, G920, and G923 equally? A.

All are listed as compatible, along with G25, G27, and Driving Force GT. Base shapes differ slightly by generation, so compare your wheel's mounting area with the product photos first.

Q. Do I need tools? A.

No. It clips onto the existing mounting mechanism and installs in a few minutes.

Tighten by hand only, and stop when resistance builds.

Q. Will it work with Thrustmaster or MOZA wheels?
A. No. It is specific to Logitech G-series mounting hardware.

Q. How much does it cost? A.

¥3,118 on Amazon.co.jp as of 8 June 2026.

Prices change, so verify at purchase time. A listing priced far above that is likely a complete wheel, not the clamp.

Q. Can I reuse it on a direct-drive wheel later? A.

No. Torque levels and mounting systems are completely different.

If an upgrade is coming, put the money toward a stand or rig instead.
