Hope Tech 4 EVO TR4 Review: Trail Power, GR4 Comparison, and Who It Suits
The Hope Tech 4 EVO TR4 is the brake I would look at before jumping straight to the GR4. It is still a four-piston Hope brake, still uses the newer EVO lever and caliper updates, and still has enough power for proper mountain-bike use. The difference is that Hope positions the TR4 as the trail brake in the EVO range, not the maximum-power gravity brake.
That makes it interesting for riders who want more than a light two-piston setup but do not need the biggest brake Hope makes. The TR4 sits in the useful middle: stronger and more serious than the EVO X2, calmer and more trail-focused than the EVO GR4, and a natural upgrade path for riders who liked the older E4 idea but want the newer lever, bleed, and caliper changes.
Quick verdict
The Hope Tech 4 EVO TR4 makes the most sense for trail, aggressive trail, all-mountain, lighter enduro, heavier trail riders, and e-MTB riders who want strong four-piston braking without choosing Hope’s most powerful gravity brake. It is not the lightest or cheapest brake, but it gives a strong mix of power, modulation, serviceability, and adjustability.
If you ride long downhill tracks, bike-park laps, heavy e-bike terrain, or regularly overheat smaller brakes, the Hope Tech 4 EVO GR4 review is probably the better comparison. If your bike is short-travel, XC-leaning, or you care more about weight than power, the TR4 may be more brake than you need.
What the TR4 is meant to do
Hope’s EVO TR4 product page calls it a four-piston trail brake for medium-duty use, with a firm and consistent lever feel. That “medium-duty” wording needs context. It does not mean weak. It means TR4 is the balanced trail option inside a range that also includes the maximum-power GR4.
On Hope’s EVO range page, the TR4 sits between the GR4 and X2. GR4 is the gravity and e-bike benchmark. X2 is the lighter two-piston option for downcountry and XC use. TR4 is the four-piston trail brake for riders who want power with firm lever feel and braking control.

| Pad note | Larger pad shared with the GR4 caliper for lever feel and consistency |
| Hose options | Black hose or braided hose, depending on the version |
| Best use | Trail, aggressive trail, all-mountain, lighter enduro, heavier riders, and riders who want four-piston control without GR4-level power |
Who should choose TR4?
Choose the TR4 if your current two-piston brakes feel short on control, if you want more power for a heavier trail bike, or if you ride steep enough terrain that brake consistency matters but you do not need a downhill brake. This is the kind of brake that makes sense on a modern trail bike with real tires, real speeds, and occasional long descents.
It also suits riders who want Hope’s serviceable construction and color options without going straight to the biggest caliper. If you like the idea of the EVO GR4 but already know you do not need maximum power, the TR4 is the more sensible first look.
Who should skip it?
Skip the TR4 if your riding is mostly XC, smooth local loops, or short-travel riding where brake weight and low drag matter more than four-piston power. Hope’s EVO X2 exists for a reason, and it is the cleaner choice for lighter bikes when the rider does not need a bigger four-piston caliper.
Also skip it if you are already overheating brakes on long gravity tracks or running a heavy e-MTB in steep terrain. In that case, do not buy the middle option and hope it behaves like the maximum-power option. Look at GR4 instead.
TR4 vs GR4
The TR4 and GR4 are close enough in name that they are easy to confuse, but they are not aimed at the same rider. TR4 is the trail four-piston brake. GR4 is the maximum-power gravity brake. Hope says the GR4 uses the largest pistons for the greatest power, while the TR4 is about power balanced with firm lever feel and braking control.
That distinction should guide the purchase. If you are building a trail or all-mountain bike and want strong braking without going overboard, TR4 is the cleaner fit. If you are building an e-MTB, downhill bike, bike-park machine, or heavy enduro setup, GR4 is the brake to compare first.
TR4 vs X2
The X2 is the lighter two-piston option in the EVO range. It makes sense for downcountry, XC, and lighter trail use where you want modulation and lower weight more than outright power. The TR4 makes sense when the rider wants a stronger front and rear brake, more heat capacity, or a more confident four-piston feel.
A Reddit discussion about TR4 vs X2 on a short-travel bike shows the real buyer question well: more brake can reduce hand fatigue, but it can also feel touchier than necessary if the terrain, tires, and rider weight do not ask for it. Treat that as rider-question context, not a universal rule.
TR4 vs older E4
The older E4 was the obvious Hope trail/enduro four-piston brake for years. The EVO TR4 takes that role into the newer EVO range. Hope says the TR4’s larger pistons increase the brake ratio by about 6.5 percent compared with the Tech 4 E4 brake system, and the revised bore-cap design reduces caliper width for frame clearance.
That makes TR4 more than a color refresh. The lever blade, cam, bleed port, piston guidance, caliper packaging, and pad story have all moved on. If you already own E4 brakes that are working well, that does not force an upgrade. If you are buying new, TR4 is the current trail four-piston Hope option to judge.
Lever feel and setup notes
The EVO lever is a big part of the story. Hope says the new cam design reduces free lever stroke while keeping modulation in the braking zone, and the EVO range adds updated lever-blade options. Standard blades come with the brakes, while Power and Control blades exist for riders who want different lever positions and leverage feel.
That is useful, but it should not be treated as a shortcut around proper setup. A TR4 still needs a clean bleed, centered caliper, bedded pads, and the correct rotor choice. If the brake feels vague, noisy, or inconsistent, check setup before blaming the brake. Our Hope Tech 4 Easy Brake Bleed Kit review covers why the correct bleed process matters on this family of brakes.
Rotor and mount checks
The TR4 buying decision should include rotor diameter, mount choice, fork and frame clearance, and the kind of riding you actually do. A bigger rotor can make the same brake feel more powerful and more consistent on long descents, but it also needs the right mount and enough clearance. Do not choose the caliper in isolation.
If your problem is heat, consider rotor size and pad compound before assuming you need the GR4. If your problem is that your current brakes are simply underpowered, TR4 may solve it without going to the heaviest-duty option. If your problem is downhill-level heat, the answer may be GR4, larger rotors, different pads, or all of the above.
What riders are asking in the real world
Early rider discussion around the EVO range is not as deep as the years of feedback around older Hope brakes, but the questions are already clear. Riders are comparing TR4 against X2 for short-travel bikes, against GR4 for maximum power, and against non-Hope brakes where lever feel and serviceability are big parts of the decision.
An EMTB Forums thread about Hope Tech 4 EVO brakes is useful because it shows how quickly riders separate GR4 and TR4 by use case. One rider chose GR4 because they wanted the most power and light lever effort, while another asked whether the brakes were the TR version. That is exactly the decision point: buy TR4 because it matches the bike, not because it is almost GR4.
Pros and cons
- Pros: strong four-piston trail braking, serviceable Hope construction, newer EVO lever and bleed-port updates, tool-free reach and bite-point adjustment, shared larger pad with GR4, color options, and a more sensible trail fit than GR4 for many riders.
- Cons: expensive, heavier and more powerful than some short-travel bikes need, still needs careful setup, early long-term rider feedback is limited, and riders doing serious gravity or heavy e-bike use may still be better served by GR4.
Bottom line
The Hope Tech 4 EVO TR4 is the sensible four-piston EVO brake for riders who want real power without automatically choosing the biggest brake in the range. It is the brake I would shortlist for modern trail, aggressive trail, all-mountain, and lighter enduro bikes where control matters but GR4 power would be unnecessary.
The main warning is simple: choose it because it fits your riding. If your bike is light and fast, X2 may be enough. If your bike is heavy and gravity-focused, GR4 may be the better answer. TR4 is the middle option, and for a lot of trail riders, that middle option is exactly the point.
FAQ
Is the Hope EVO TR4 better than the GR4?
Not better, just different. TR4 is the trail four-piston brake. GR4 is the maximum-power gravity brake. Choose TR4 for balanced trail control and GR4 for heavier, faster, steeper, or more heat-heavy riding.
Is the TR4 too much brake for a short-travel bike?
It can be. On a short-travel XC or downcountry bike, the EVO X2 may be a cleaner match. TR4 makes more sense if rider weight, terrain, tire grip, or descent length justify four-piston power.
Does TR4 replace the old E4?
Functionally, yes, it occupies the newer four-piston trail role in Hope’s EVO range. It is not just an E4 with a new name, though; the lever, cam, bleed system, caliper details, and pad story have changed.
Should I choose black hose or braided hose?
Choose based on routing, durability preference, look, and budget. Braided hose can be attractive for riders who want the tougher premium setup, but black hose is simpler and usually the more cost-effective choice.
Does TR4 need careful bleeding?
Yes. The EVO bleed port should make the process easier, but the brake still depends on a clean DOT-fluid bleed, correct fittings, centered caliper, and properly bedded pads.
