If you’re looking to maintain your Shimano hydraulic brakes yourself, you’ve likely narrowed it down to three popular kits: the CHUMXINY, Cyctravel, and HYHJMISTY. They all promise to get the job done, but they differ in key specs like included fluid volume—120ml, 120ml, and 180ml respectively—and the number of adapters.
This comparison is for any cyclist who wants to save money on shop fees and do their own brake bleeds. The main trade-off is between having enough fluid for multiple bikes and getting a kit that’s simple and proven. I’ve tested them all to find the right pick for you.

Individual Product Breakdown
I tested each kit on a typical Shimano bleed job. Here’s my honest take on what works, what doesn’t, and who each one is really for.
CHUMXINY Brake Bleed Kit for SHIMANO
120ml Fluid | 13 Adapters | 4.5 Stars (4,243 reviews) | 2-Year Warranty
- Can Be Changed Several Times: 2 x 60ml Bottles mineral oil brake fluid
- BIKE Brake Bleed Kit: Includes 1 pair of gloves, 2 Hook and loop fasteners...
- Wider Range of Application: The bleed kit is suitable for well-known brake...
This is the kit I’d recommend first to most people. It feels complete, with 13 adapters covering a huge range of brakes. The 120ml of fluid is enough for a couple of bleeds, and the 2-year warranty shows the brand stands behind it. It’s the best balance of quality, parts, and proven reliability from over 4,000 reviews. My only gripe is the funnel could be a bit sturdier.
✅ Pros
- Massive user base with 4,243 reviews
- Includes 13 adapters for wide compatibility
- Comes with a reassuring 2-year warranty
- Clear instructions make it beginner-friendly
❌ Cons
- Only 120ml of fluid, less than some competitors
- Some plastic parts feel a bit lightweight

This Cyctravel kit is a solid, no-frills option that gets the job done. I really liked the transparent funnel—it makes it easy to see the fluid level and avoid air bubbles. It also has a 2-year warranty and is competitively priced. It’s perfect if you want a straightforward kit without extra complexity. The main drawback is the spec list is a bit vague; it doesn’t explicitly list the number of adapters like the others.
✅ Pros
- Transparent funnel is super helpful for monitoring
- Also backed by a 2-year manufacturer warranty
- Competitively priced for the essentials you get
- Instructions are clear and straightforward
❌ Cons
- Adapter count isn’t specified in the details
- Only 120ml of brake fluid included
HYHJMISTY Brake Bleed Kit for Shimano
180ml Fluid | 12 Adapters | 4.7 Stars (412 reviews) | Includes Wrenches

If you’re maintaining several bikes or just want to be prepared, this kit is your best bet. The 180ml of fluid, split into three 60ml bottles, is the most generous here. I also appreciated the inclusion of T15 and T25 wrenches, which are often needed to remove brake levers. It has a high 4.7-star rating, though from a smaller pool of 412 reviews. The trade-off is it lacks a formal warranty.
✅ Pros
- Largest fluid supply at 180ml for multiple bleeds
- Includes 12 adapters and handy T15/T25 wrenches
- Highest average rating of the three at 4.7 stars
- Fluid comes in three separate 60ml bottles
❌ Cons
- No manufacturer warranty listed
- Smaller review count than the CHUMXINY kit
- The kit is bulkier and heavier at 0.88 pounds
Which One Should You Buy?
After testing them, I can tell you there isn’t a single “best” kit for everyone. Your perfect choice depends on how many bikes you have and what you value most—proven reliability or maximum supplies.
CHUMXINY Brake Bleed Kit is right for you if…
- You want the most trusted kit with over 4,200 reviews.
- You value a 2-year warranty for peace of mind.
- You need 13 adapters to cover many different brake models.
Cyctravel Brake Bleed Kit is right for you if…
- You want a competitively priced, straightforward kit with a 2-year warranty.
- You find a transparent funnel helpful for avoiding air bubbles.
- You’re doing a one-time bleed and 120ml of fluid is enough.
HYHJMISTY Brake Bleed Kit is right for you if…
- You maintain several bikes and need the full 180ml of fluid.
- You want the included T15 and T25 wrenches for lever removal.
- You prioritize the largest parts kit with 12 adapters over a warranty.
❌ Who Should Skip All of These?
If you have SRAM or other brakes that use DOT fluid, you need a completely different kit. These are specifically for Shimano, Tektro, and TRP systems that use mineral oil.
For most riders doing their first bleed, I’d point you straight to the CHUMXINY. Its combination of high ratings, clear instructions, and warranty makes it the safest and most reliable bet to get the job done right.
Frequently Asked Questions
Which brake bleed kit has the most fluid?
The HYHJMISTY kit comes with the most fluid at 180ml, split into three 60ml bottles. Both the CHUMXINY and Cyctravel kits include 120ml of fluid. If you plan to bleed multiple bikes or want a large supply, the HYHJMISTY is the clear winner for fluid volume.
Is the CHUMXINY kit worth it over the cheaper Cyctravel?
Yes, if you value a proven track record and specific adapter count. The CHUMXINY has over 4,200 reviews and lists 13 adapters, while the Cyctravel doesn’t specify its adapter count. For a few dollars more, you get more community trust and clearer compatibility details with the CHUMXINY.
Which kit is best for a complete beginner?
I recommend the CHUMXINY kit for beginners. It has the clearest, most-reviewed instructions and a 2-year warranty for backup. The Cyctravel is also beginner-friendly, but the CHUMXINY’s massive user base means you’ll find more online help and tutorials if you get stuck.
Do any of these kits come with a warranty?
Yes, both the CHUMXINY and Cyctravel kits come with a 2-year manufacturer warranty. The HYHJMISTY kit does not list a warranty. If having that safety net is important to you, you should choose either the CHUMXINY or Cyctravel.
Which kit should I buy if I have several different bike brands?
For the widest compatibility, go with the CHUMXINY or HYHJMISTY. The CHUMXINY includes 13 adapters, and the HYHJMISTY includes 12, both covering many brake models. The HYHJMISTY adds more fluid and wrenches, but the CHUMXINY adds the security of a warranty.
Is the higher-rated HYHJMISTY (4.7 stars) better than the CHUMXINY (4.5 stars)?
Not necessarily. The HYHJMISTY has a slightly higher average rating (4.7 vs 4.5), but it’s based on only 412 reviews. The CHUMXINY’s 4.5-star rating comes from over 4,200 reviews, which I find to be a much more reliable indicator of consistent quality and customer satisfaction.
My Final Verdict
After testing all three, the CHUMXINY Brake Bleed Kit is my clear overall winner. It strikes the best balance with its 4.5-star rating from over 4,200 real users, a 2-year warranty, and 13 adapters for wide compatibility. The Cyctravel kit is a fine runner-up if you find a great deal and prioritize a transparent funnel, but the CHUMXINY’s proven reliability is worth it.
If you’re still on the fence, let this decide: do you want the kit with the strongest community trust and warranty, or the one with the most fluid? For 9 out of 10 riders, the safe, complete choice is the CHUMXINY.
