Hope Union Pedals Guide: RC, TC, GC, Cleats, Float, and Who They Suit
The Hope Union pedals are Hope’s clipless pedal range, split into three versions: RC, TC, and GC. The important point is not just which one looks best. It is whether you want a smaller race-style pedal, a trail pedal with more shoe support, or a gravity pedal with the biggest platform contact.
The second important point is cleat compatibility. Union pedals use Hope cleats. They are not a simple Shimano SPD-cleat swap, so the Union range makes most sense if you are happy to set up shoes around Hope’s cleat system.
Quick Verdict
Choose the Union RC if you want the smallest, lightest-feeling Hope clipless option for race, XC, gravel, or general off-road use where platform support is less important than clearance and low bulk. Hope’s Union RC page lists a titanium axle as standard, a 55mm Q-factor, three cartridge bearings, an IGUS bush, and two cleat options.
Choose the Union TC if you want the middle ground: more shoe contact than RC, pins for extra shoe interface, and a trail/enduro shape without going to the biggest GC body. Hope’s Union TC page describes it as a large-platform trail clip pedal with replaceable pins and a serviceable bearing/bush layout.
Choose the Union GC if you ride clipped in but still want the closest thing to a gravity platform under your shoe. Hope’s Union GC page lists a large platform, 14 replaceable pins, and a foot-plate option for maximum shoe/pedal contact.
Hope Union RC vs TC vs GC
| Model | Best fit | Main reason to choose it | Main caution |
|---|---|---|---|
| Union RC | XC, gravel, race, lighter trail use | Smallest body, titanium axle as standard, less platform bulk | Least shoe support of the three |
| Union TC | Trail, enduro, aggressive general riding | More shoe contact and optional pins without the full GC size | Still uses Hope cleats, not SPD cleats |
| Union GC | Gravity, downhill, bike-park, clipped-in riders coming from flats | Largest support, 7 pins per side or foot plates | More pedal underfoot than some riders need |
That is the simple model split. RC is the smallest. TC is the trail middle option. GC is the gravity support option. If you already know you want minimum pedal around the cleat, RC is the obvious starting point. If you want clipless retention but still like a platform under the shoe, TC and GC are the better places to look.
Cleats, Float, and Release
Hope supplies Union pedals with two cleat options. The official RC, TC, and GC pages list 4 degrees or 5 degrees of free float, with 12 degrees or 13 degrees of release angle respectively. Both cleat options also allow 2mm of lateral float.
This matters because the cleat is part of the product. If you already own several Shimano SPD shoes and pedals, do not assume you can swap cleats and keep everything universal. A Reddit discussion about Union RC pedals shows the real concern clearly: some riders like the engagement feel, but the Hope cleat system can be inconvenient if the rest of your bikes are already built around SPD.
For a one-bike setup, that may not matter much. For riders sharing shoes across road, gravel, spin bikes, commuters, and mountain bikes, it matters a lot.
Entry and Release Feel
Hope describes the Union mechanism as dual-sided and designed for easy entry, secure cleat holding, and positive release. That is the technical reason Union pedals are not just a flat pedal with a clip bolted into the middle.
Public rider feedback is broadly about the same things: entry, release, platform support, shoe contact, and whether the Hope cleat system is worth moving away from SPD. In a Union GC versus TC discussion, riders compare platform support and shoe size rather than treating all clipless pedals as the same. That is useful, but still anecdotal.
If you are sensitive to release feel, shoe tread clearance, or knee comfort, take time with cleat position and spring tension. Clipless setup is not only the pedal body. Shoe sole shape, cleat shims, tread interference, and float preference all change the result.
Platform Support and Pins
The TC and GC are the Union models to consider when shoe support matters. The TC has a larger shoe/pedal contact area than RC and uses replaceable pins. The GC goes further with a bigger platform, 7 pins per side, and an optional foot-plate setup.
That support is useful for riders who come from flat pedals, ride rough descents, or use shoes with soles that benefit from a broader contact patch. It is less important for riders who want a compact race pedal and stiff XC shoe.
There is a tradeoff. Pins can add contact and grip against the shoe sole, but they also need setup attention. In a TC and GC owner discussion, one rider mentions pin setup and cleat hardware details. Treat that as one owner’s note, not a universal issue, but it is exactly the kind of setup detail buyers should expect with a tunable clipless pedal.
Serviceability
Serviceability is one of Hope’s stronger arguments. The official Union pages list three cartridge bearings, an IGUS bush, and fully serviceable, rebuildable construction. That matters if you ride wet trails, keep pedals for years, or prefer replacing bearings and small parts instead of treating pedals as disposable.
It does not automatically make Union pedals the best choice for every rider. If you want cheap SPD-compatible pedals that you can buy anywhere, Hope may be more pedal than you need. If you want a premium clipless pedal with long-term parts logic, Union makes more sense.
Who Should Buy Union RC
Buy the Union RC if you want the cleanest Hope clipless option for XC, gravel, race-style riding, or a lighter trail bike. It is the best choice if you use stiff shoes, do not need a big pedal body, and want less platform around the cleat.
Skip RC if you are coming from flat pedals and want a lot of support under your shoe. TC or GC will usually make more sense in that case.
Who Should Buy Union TC
Buy the Union TC if you want one Hope clipless pedal for trail and enduro riding. It gives more shoe contact than RC without going all the way to the GC gravity platform.
This is the safest middle choice for many mountain-bike riders, especially if you want clipless retention but still care about platform feel.
Who Should Buy Union GC
Buy the Union GC if your riding is rough, steep, or gravity-focused and you want the largest Hope clipless platform. It suits riders who like clipless control but still want the shoe to feel supported on hard descents.
Skip GC if you are trying to save weight, want a small pedal body, or ride mostly smoother XC-style terrain. The extra platform is useful only if your riding and shoe setup actually need it.
Who Should Skip Hope Union Pedals
Skip the Union range if guaranteed SPD-cleat compatibility is your main requirement. Hope cleats are part of the system, and that can be a dealbreaker if you share shoes between several SPD pedal setups.
Also skip them if you want the cheapest clipless pedal, do not care about serviceability, or are not willing to spend time setting cleat position, spring tension, and shoe contact properly.

Clipless pedal setup is easier to assess when tire support is in the right range. If the bike feels nervous, harsh, or vague after cleat changes, compare the pedal setup with a practical baseline from the tire pressure calculator.
Bottom Line
The Hope Union range makes sense if you want a serviceable, premium clipless pedal and are comfortable using Hope’s cleat system. RC is the small race-style choice. TC is the trail middle ground. GC is the gravity option with the most shoe support.
The wrong way to buy Union pedals is by color alone. Choose by shoe, riding style, cleat commitment, and how much platform support you actually want underfoot.
