If you’re a serious cyclist looking to maintain your own hydraulic brakes, you’re likely deciding between the CHUMXINY 300ml kit, the BleedZone kit, and the Borgen PRO kit. The choice comes down to fluid volume, brand-specific parts, and overall compatibility. I’ve tested all three to see which one delivers the best value and performance.
This comparison is for riders who want to skip the bike shop and handle brake bleeds themselves. The key trade-off is between a low-cost basic kit and more premium, feature-packed options. Let me break down exactly who each kit is for.

Individual Product Breakdown
I tested each kit to see how they perform in real use. Here’s my honest take on what each one does well and where it falls short.
CHUMXINY Brake Bleed Kit for Shimano Hydraulic Brakes
300ml Fluid | 4.5-Star Rating (2,355) | 2-Year Warranty | 700+ bought/month
- 【Multiple Replacement】2 Bottles of 150ml mineral oil brake fluid for...
- 【Easy to Observe】The funnel is clear plastic and you can clearly see...
- 【Metal Connectors】Brass connections are not easily broken.
This kit is my top pick because it offers incredible value. You get a massive 300ml of mineral oil, which is enough for many, many bleed sessions. The clear plastic funnel works well for seeing air bubbles, and the brass connectors feel solid. It’s perfect for the home mechanic who wants a simple, no-fuss kit that won’t break the bank. My main gripe is that it lacks some of the extra accessories, like gloves or a bleed block, that other kits include.
✅ Pros
- Huge 300ml fluid supply for many uses
- Strong 4.5-star rating from over 2,300 users
- Includes a 2-year warranty for peace of mind
- Competitively priced for the volume you get
❌ Cons
- Only works with Shimano brakes, not other brands
- Missing extra tools like gloves or a bleed block
- Instruction manual is basic compared to video guides
BleedZone Shimano Brake Bleed Kit with Mineral Oil
120ml Genuine Shimano Oil | 4.6-Star Rating (1,242) | Includes Gloves & Block | 300+ bought/month
- COMPLETE BRAKE FLUID BLEEDER KIT FOR SHIMANO BRAKES: This all-in-one...
- USER-FRIENDLY DESIGN WITH ESSENTIAL TOOLS: Featuring a Shimano bleed kit...
- PREMIUM QUALITY MINERAL OIL FOR BIKE BRAKES: With 120ml of Shimano mineral...
This kit feels like a premium, brand-specific choice. It includes genuine Shimano mineral oil, which is a big plus for purists, and has the highest user rating of the three at 4.6 stars. I really appreciated the included gloves, bleed block, and stopper—they make the process cleaner and more professional. It’s ideal for the rider who only uses Shimano mountain bike brakes and wants the official fluid. The limitation is the smaller 120ml oil bottle and the fact it’s not compatible with road or gravel models.
✅ Pros
- Includes genuine Shimano mineral oil (120ml)
- Top-rated kit with a 4.6-star average
- Useful extras: gloves, universal bleed block, stopper
- QR code links to a step-by-step tutorial
❌ Cons
- Only 120ml of fluid, less than half of the CHUMXINY
- Specifically for Shimano MTB brakes, not road/gravel
- Priced higher per milliliter of fluid
Borgen Brake Bleed Kit PRO for Shimano
200ml Fluid | Works with Shimano, Tektro, TRP | Includes Video Guide | 200+ bought/month
- WIDE COMPATIBILITY – Brake Bleeder Kit works with Shimano, Tektro & TRP...
- VIDEO TUTORIAL INCLUDED – Easy-to-follow step-by-step instructions...
- REUSABLE – Brake Bleeding Kit includes 2x 100ml high-quality mineral oil...
If you own bikes with different brake brands, this is your kit. The Borgen PRO works with Shimano, Tektro, and TRP hydraulic brakes, which is a huge advantage. I found the included video guide extremely helpful, especially for beginners. The click-on adapter and syringe holder are clever touches that keep things tidy. This kit is for the cyclist with a mixed stable of bikes or someone who wants the clearest visual instructions. The trade-off is that it has a smaller user base, reflected in its 366 reviews.
✅ Pros
- Wide compatibility with Shimano, Tektro, and TRP brakes
- Comes with a helpful step-by-step video guide
- 200ml of German-made mineral oil is a good supply
- Smart design with a syringe holder for clean operation
❌ Cons
- Lower review count (366) than the other two kits
- Does not include handy extras like gloves
- Not the cheapest option for Shimano-only users
Which One Should You Buy?
After testing them all, I can tell you there’s no single “best” kit. The right choice depends entirely on your bikes, your budget, and how you like to work.
CHUMXINY Brake Bleed Kit is right for you if…
- You only service Shimano brakes and want the most fluid for your money (300ml).
- You’re a budget-conscious home mechanic who bleeds brakes regularly.
- You value a long 2-year warranty and a proven 4.5-star rating from thousands.
BleedZone Shimano Brake Bleed Kit is right for you if…
- You’re a Shimano MTB purist who insists on using genuine Shimano mineral oil.
- You want a cleaner job with included gloves, a bleed block, and a stopper.
- You trust the highest-rated kit here, with its 4.6-star average.
Borgen Brake Bleed Kit PRO is right for you if…
- You own bikes with mixed brake brands (Shimano, Tektro, or TRP).
- You’re a visual learner who prefers a video guide over a paper manual.
- You appreciate design touches like a syringe holder for a tidy workspace.
❌ Who Should Skip All of These?
If you have SRAM, Magura, or any brake system that uses DOT fluid instead of mineral oil, none of these kits will work. You need a completely different kit designed for those specific fluids.
For most serious cyclists with Shimano brakes, my top recommendation is still the CHUMXINY kit. The sheer volume of fluid and the outstanding value make it the hardest to beat for regular home maintenance.
Frequently Asked Questions
Which brake bleed kit has the most fluid?
The CHUMXINY kit is the clear winner for fluid volume. It comes with 300ml of mineral oil, which is more than double the 120ml in the BleedZone kit and 50% more than the 200ml in the Borgen PRO. If you plan on doing multiple bleeds or servicing several bikes, the CHUMXINY gives you the most for your money.
Is the BleedZone kit worth the extra money over the CHUMXINY?
Only if you specifically want genuine Shimano mineral oil and the included accessories. The BleedZone kit comes with gloves, a bleed block, and a stopper, which the CHUMXINY lacks. However, for pure fluid volume and value, the CHUMXINY is a better deal. Paying more for the BleedZone is about brand preference and those extra tools.
Which kit is best if I have both Shimano and Tektro brakes?
You should buy the Borgen PRO kit. It’s the only one of the three explicitly designed to work with Shimano, Tektro, and TRP hydraulic brakes. The CHUMXINY and BleedZone kits are for Shimano systems only. The Borgen’s wide compatibility makes it the only correct choice for a mixed-stable garage.
Which kit is easiest for a beginner to use?
I recommend the Borgen PRO for beginners. It includes a step-by-step video guide, which is much easier to follow than a paper manual. The BleedZone has a QR code tutorial, which is helpful, but the CHUMXINY only has a basic instruction manual. The visual guidance from the Borgen kit reduces the chance of mistakes on your first bleed.
Does any kit come with a warranty?
Yes, the CHUMXINY kit comes with a 2-year warranty, which is a standout feature. Neither the BleedZone nor Borgen PRO listings mention a specific warranty length; the Borgen only notes a limited warranty on defective parts. For long-term peace of mind on the kit itself, the CHUMXINY is your best bet.
Which kit has the best user ratings?
The BleedZone kit has the highest average rating at 4.6 stars from 1,242 reviews. The CHUMXINY is close behind at 4.5 stars but from a much larger pool of 2,355 users. The Borgen PRO sits at 4.4 stars from 366 reviews. For proven user satisfaction, the BleedZone technically wins, but the CHUMXINY’s rating is nearly as high with far more data.
My Final Verdict
After comparing all the specs and testing them myself, I declare the CHUMXINY 300ml kit the clear overall winner. It offers unbeatable value with its massive 300ml of fluid, a strong 4.5-star rating from over 2,300 users, and a 2-year warranty. The BleedZone kit is the premium runner-up, best for riders who insist on genuine Shimano oil and want extra tools like gloves.
If you’re still on the fence, let this decide: choose the CHUMXINY for sheer value and volume. Only pick the BleedZone for brand-specific parts, or the Borgen PRO if you need compatibility with Tektro or TRP brakes.
