Sensah Empire Pro Review: Inside a Low-Cost 12-Speed Road Groupset

Introduction

A complete 12-speed road groupset with disc brakes for around £300 is an unusual proposition, and the Sensah Empire Pro is one of the more established ways to find out what that money actually buys. The set arrives as a full mechanical package, and while the core parts come from Sensah, the bundle also includes components from other manufacturers.

Ordering is straightforward and postage was free. The outer carton arrived noticeably battered after its journey from China, but every part inside was individually wrapped and nothing was damaged.

This article covers what is in the bundle, how the parts are finished, the measured weight of each component, and the practical details worth knowing before ordering. If you are considering a low-cost groupset for a self-built bike, these are the points that decide whether it will suit you.

What Comes in the Box

The bundle is listed as a complete groupset, so it covers nearly everything needed for a build, with a few parts sourced from other companies.

• Rear derailleur: mechanical, 12-speed, with a carbon cage on one side
• Front derailleur: mechanical, supplied in protective wrapping
• Chain: 12-speed, 126 links, supplied with a quick link in its own box
• Shifters: a pair with carbon levers and inner cables included
• Cassette: 11-32T, built as a single piece apart from the two smallest sprockets, with splines that suit a Shimano HG freehub body. Other ratios can be selected when ordering.
• Bottom bracket: threaded BSA, the only option offered in this particular bundle
• Crankset: aluminium, 170mm, with a 50/34 double chainring setup and a preload adjuster on one side
• Disc rotors: 160mm front and rear, six-bolt, with the mounting bolts and adapters included
• Brake calipers: mechanical, cable-actuated, with fittings
• Instruction manual: a basic illustrated booklet with English on one side and Chinese on the other, covering gear setup only

The brakes come from a different manufacturer, so the manual does not include any guidance for them.

Build Quality and First Impressions

The rear derailleur feels well made. The jockey wheels turn smoothly and the carbon cage on one side looks tidy. The front derailleur has an engraved logo that is slightly concave, a detail repeated on the body of the mechanism, and it feels substantial in the hand.

The crankset has become one of the more likeable parts of the bundle. The aluminium finish is clean, the threads are tidy, there are no rough edges, and the torx bolts holding the crank to the spider look neat. The printed branding is crisp and does not rub off.

The shifters use carbon levers, one for the rear and one for the front, and come with inner cables. The hoods are where things get odd: the right hood has a soft rubber feel while the left has a much grippier texture, which looks like an inconsistency rather than a deliberate design choice. The hoods are also noticeably small and narrow compared with other groupsets, though the shifters themselves feel solid and comfortable in the hand.

The chain arrives completely dry, with no grease or lubricant on it at all. That is unusual for a 12-speed chain and means it will need lubing before it goes anywhere near a bike.

The brake calipers are the least elegant part of the package. They are heavy and bulky rather than sleek, and while that does make them feel solid, they are clearly the component most worth upgrading later. The cassette is similarly heavy, built as one piece apart from the two smallest sprockets.

Who This Groupset Is For

This groupset suits riders building a bike to a tight budget who want 12 speeds and disc brakes without paying brand-name prices. It also suits anyone comfortable doing their own installation, cable routing, and derailleur setup, since the included manual covers gears only.

It is a less obvious fit for riders who need a press-fit bottom bracket, because this bundle ships with a threaded BSA unit only, and for riders who want the matched finish and consistent small details of a premium groupset.

Main Strengths

Price is the headline. For roughly £300 the bundle delivers a complete 12-speed mechanical drivetrain with cable-actuated disc brakes, including cranks, cassette, rotors, and a bottom bracket.

The measured weights add useful context. On the scales, the rear derailleur came in at 197g, the front derailleur at 95g, the chain with its quick link at 259g, the shifters as a pair at 440g, the bottom bracket at 77g, the brake calipers at 441g, the cassette with its lock ring at 361g, the rotors at 196g, and the crankset at 709g. That totals 2,819g.

The bundle is quoted at around 2,420g, but that figure applies to the caliper brake version listed on the same product page, and no weight is quoted for the disc brake version, so the difference is expected. For context, Shimano 105 is roughly 2,500g, Ultegra around 2,200g, and Dura-Ace below 2,000g, depending on the version and what is included in the figure.

Everything here is 12-speed and, in theory, compatible with SRAM drivetrains. That means a SRAM chain could be substituted if you would rather run a more familiar chain.

Things to Consider Before Buying

• The chain arrives dry and needs lubricant before use.
• The shifter hoods do not match in texture, and the hoods are small and narrow.
• The brake calipers are heavy and bulky, and they are the component most likely to prompt an upgrade.
• The manual covers gear setup only, because the brakes come from another manufacturer.
• The disc brake version is heavier than the quoted bundle weight, which refers to the caliper brake version.
• Only a threaded BSA bottom bracket is offered in this bundle.
• The rotors are six-bolt. If your hubs use center lock, you will need adapters, and adapters only work in that direction: a six-bolt rotor can be fitted to a center lock hub, but not the reverse.
• Packaging may arrive battered, though the individual parts were well wrapped.

Buying Advice

Order through the official Sensah store. That matters for one specific reason: the newest shifters use an aluminium piece under the hood, replacing a plastic part that was known for snapping. Ordering from the official store is the most reliable way to receive the current revision.

Choose your cassette ratio and bottom bracket type at checkout, since the bundle offers limited options and the parts appear to be assembled to order. Budget for chain lubricant as well, because the chain ships dry.

If the disc brake version’s extra weight matters to you, it is worth remembering that the quoted weight for the bundle refers to the caliper brake version, and the difference measured here comes mainly from the calipers and rotors.

Before committing, consider how much of the build you want to handle yourself. This is a fully mechanical groupset, and the supplied manual walks through the gear setup with pictures. Setup is a matter of patience rather than electronics.

Conclusion

The Sensah Empire Pro bundle delivers a great deal of hardware for the money. A complete 12-speed mechanical drivetrain with disc brakes, including cranks, cassette, rotors, and a bottom bracket, at around £300 is difficult to match elsewhere. The crankset and derailleurs feel well made for the price, and the alloy reinforcement under the newest shifter hoods addresses a known weak point from earlier versions.

The trade-offs are equally clear. The calipers are heavy and bulky, the shifter hoods are small and do not match in texture, the chain arrives dry, and the disc brake build weighs more than the figure quoted for the bundle. None of these are deal-breakers at this price, but they are the details to weigh against a brand-name groupset. For a budget build where you are doing the work yourself, this bundle is worth a serious look.
