Quick Answer: The Rocket Cinquantotto (R58) is a hand-built Milanese dual-boiler espresso machine currently priced at $3,350-$3,500 depending on retailer (Seattle Coffee Gear vs. Pro Coffee Gear) — up from the roughly $3,000 this site previously cited. It pairs a 58mm E61 group with two independent, PID-controlled boilers (a 0.58L brew boiler and a 1.7-1.8L steam boiler), a touchscreen PID with a built-in shot timer, and a quiet rotary pump that can run from its 2.5L tank or be plumbed directly to a water line. The honest read: it’s the clearest step up from a heat exchanger like the Rocket Appartamento, and it still undercuts the rival ECM Synchronika II by roughly $100-$250 — but it no longer carries the sub-$3,000 price tag some older reviews still cite.
The Cinquantotto — Italian for “58,” a nod to the 58mm E61 group it shares with cafés worldwide — is the machine most buyers mean when they say “Rocket R58.” It’s been Rocket’s core dual-boiler offering for years, referenced constantly across this site’s best Rocket espresso machine roundup and Rocket vs ECM comparison, but it’s never had its own dedicated review here. Here’s what the machine actually gives you, what it costs right now, and who should buy it instead of stepping up or down the Rocket lineup.
Rocket Cinquantotto, by the numbers
| Spec | Rocket Cinquantotto (R58) |
|---|---|
| Price | $3,350-$3,500 (varies by retailer) |
| Group head | 58mm E61, dual (mechanical + PID-assisted) pre-infusion |
| Boilers | Dual — 0.58L brew + ~1.7-1.8L steam, brass/copper in a stainless case |
| Temperature control | Touchscreen PID, independent brew/steam settings |
| Extras | Built-in low-profile shot timer |
| Pump | Rotary — tank or plumb-in |
| Water tank | 2.5 L |
| Dimensions | ~17"W x 17"H x 22.75"D (with portafilter) |
| Warranty | Up to 3 years (varies by authorized dealer) |
The number worth sitting with is the $3,350-$3,500 price spread itself. Per Seattle Coffee Gear and Pro Coffee Gear’s own current listings, the same machine sells for meaningfully different prices depending on where you buy it — a roughly $150 swing before you’ve even compared it to a competing brand. That’s on top of a real increase from the ~$3,000 figure this site’s own Rocket vs ECM comparison originally used before its October 2026 price update.
The Cinquantotto, tested
Rocket Cinquantotto (R58)
- Two independent boilers — a 0.58L brew boiler and a ~1.7-1.8L steam boiler — each under touchscreen PID control.
- 58mm E61 group with dual pre-infusion, backed by a built-in low-profile shot timer.
- Quiet rotary pump that runs from a 2.5L tank or plumbs directly into a water line.
- Hand-built in Milan from brass, copper, and stainless steel — the modern successor to the original R58.
Stocking up on beans and milk before it arrives? Try Amazon Fresh for grocery delivery while you wait for the machine itself. In daily use, the touchscreen PID is the feature that actually changes how you brew: instead of relying on the E61 group’s thermal mass alone, as the single-boiler Rocket Appartamento does, you can hold the brew boiler at one temperature and the steam boiler at another, then adjust either independently as beans or roast levels change. The built-in shot timer removes the need for a separate stopwatch or phone app, which matters once you’re dialing in extraction time alongside dose and grind — see our how to dial in espresso guide for how those variables interact.
The rotary pump is the other quiet upgrade. It’s noticeably quieter than the vibration pumps on Rocket’s own HX machines, and because it can draw from a plumbed water line instead of just the 2.5L tank, it’s genuinely ready for a permanent installation — our how to plumb in an espresso machine guide covers what that install actually involves.
How it compares to the closest alternatives
| Rocket Cinquantotto | Rocket Appartamento 2.0 | ECM Synchronika II | |
|---|---|---|---|
| Price | $3,350-$3,500 | $2,150-$2,200 | ~$3,599 |
| Boiler | Dual (0.58L brew + ~1.8L steam) | Single 1.8L HX | Dual (0.75L brew + 2L steam) |
| PID | Yes, touchscreen, independent control | No | Yes, OLED |
| Pump | Rotary, tank or plumb-in | Vibration | Rotary, tank or plumb-in |
| Best for | Independent temp control at a lower price than ECM | Entry Milan heritage, lowest Rocket price | Bigger boilers, pre-infusion modes |
- Get the Cinquantotto if you want true dual-boiler independence — separate brew and steam temperatures — without paying ECM’s roughly $100-$250 premium for slightly bigger boilers.
- Step down to the Appartamento 2.0 if a single heat-exchanger boiler and mechanical-only pre-infusion are enough, and you’d rather save over $1,100 and stay inside the Rocket name.
- Step up (or sideways) to the ECM Synchronika II if you want bigger boilers and both active and passive pre-infusion modes — full breakdown in our Rocket vs ECM comparison.

Who should buy the Cinquantotto
Buy it if you’ve outgrown a heat exchanger and specifically want independent brew and steam temperature control, a touchscreen PID, and Rocket’s hand-built-in-Milan construction — and you’d rather save a few hundred dollars over the ECM Synchronika II without giving up the dual-boiler upgrade. It’s also a strong pick if you plan to plumb the machine in permanently, since the rotary pump and plumb-in readiness are built for that from the start.
Skip it if you don’t yet need two independent boilers — the Rocket Appartamento 2.0 delivers the same E61 group and Milanese build for over $1,100 less, and most home baristas who steam one or two drinks at a time won’t feel the ceiling of a single heat exchanger. Skip it too if the ECM Synchronika II’s larger boilers and dual pre-infusion modes matter more to you than saving $100-$250 — our Rocket vs ECM comparison breaks down that trade-off in full.
The bottom line
The Rocket Cinquantotto (R58) remains one of the better values at the true dual-boiler tier — a hand-built, touchscreen-PID machine with independent brew and steam control that still undercuts the ECM Synchronika II, even after its own price climbed to $3,350-$3,500. The honest caveat is that “R58” pricing you’ll find in older reviews and forum threads is stale; budget closer to $3,400 than $3,000. For buyers who don’t need that second boiler, the Rocket Appartamento 2.0 remains the better-value entry into the Rocket name — see our best dual boiler espresso machine guide for how the Cinquantotto stacks up against the wider dual-boiler field.
