Sensah Empire Groupset and EE Brakes: An AliExpress Race Build That Wins
A closer look at the two components behind a fast, low-cost race bike: the Sensah Empire groupset and lightweight EE-style rim brakes.
Introduction
A complete race bike assembled almost entirely from AliExpress parts sounds like a gamble. This one is not a thought experiment: apart from the saddle, crankset, bottle cages and top cap, every component came from the platform, including the aero frameset, the deep-section wheels, the narrow cockpit, and the two parts that shape how the bike shifts and stops.
The Sensah Empire groupset and a set of lightweight EE-style rim brakes sit at the centre of that story. Both show what careful part selection can deliver when the budget stays low, and both come with trade-offs that are worth understanding before you order anything.
What Makes This AliExpress Build Work
The build works because the parts were chosen with one clear goal: aero efficiency and low weight at a fraction of mainstream pricing. Every component was researched before purchase, with buyer feedback checked for the brakes, the groupset, the frame and the cockpit parts. Components with hundreds of reviews and a consistent track record made the final cut, and the finished bike has already been raced at elite level.

That approach also explains why the finished bike does not feel like a compromise. The frame, wheels, bars and stem all reinforce the same aero-focused riding position, so the gains stack up instead of cancelling each other out.
Sensah Empire Groupset: Budget Shifting That Performs
The Sensah Empire groupset covers both 12-speed and 11-speed rim brake setups, with the same style of shifter across versions. Shifting performance has been strong overall, the parts are light, and the groupset has already carried this bike to race wins. It is a genuinely usable alternative to mainstream groupsets at a much lower price.
Small quality-control differences are part of the deal between batches. Reported niggles include parts working loose and rattling, hoods that can come loose, a derailleur b-screw that is not tight enough, and a loose bolt at the derailleur mount that lets the derailleur sit at a slight angle. Some examples have a small protrusion on the shifter. None of this stopped the groupset from performing, but it does show that finishing and consistency are not the same as a premium brand’s.
EE Brakes: Weight Savings at a Fraction of the Price
These rim brakes carry a well-known brand name but are replicas rather than genuine parts, and that is worth stating plainly before anything else. The appeal is straightforward: they are reported to brake extremely well, they are machined to a very similar standard, and they weigh only around 20 grams more than the original design. At roughly £100 compared with about £600 for the original, and around 100 grams lighter than typical rim brake calipers, the savings in both weight and cost are substantial. Across the whole build, the brakes account for hundreds of grams saved.

For riders chasing low weight on a rim brake frame, that combination is hard to ignore. Buyers should still weigh up the replica aspect before ordering, since the product is sold under another company’s name.
The Frame, Wheels, and Cockpit Around Them
The frameset comes from Elves, a Chinese brand with a strong following across Asia, and it cost around £800. It weighs just under 1,100 grams in a 54 cm aero size, and the paint finish is well executed, although the white section is not clear coated and the interior of the frame arrived slightly tacky, with a sharp piece of carbon inside the headset area that needed cleaning up. That is the trade-off at this price: the design and the weight are there, the final finishing is not.
The wheels follow the same aggressive logic, with 82 mm at the rear and 60 mm at the front. They are very deep, very aero and noticeably fast on flat roads, though they are less suited to technical circuits. Up front, a carbon stem with a minus 17 degree angle and 120 mm length is paired with 36 cm bars and shifters turned inwards for a narrow, aero position. Fully internal cable routing through the stem creates a tight bend that cables do not love, and routing through the down tube would run more smoothly, but the stem route was chosen for the clean, fully internal look.
Research First: Choosing AliExpress Parts with Confidence
Buying from AliExpress is not the same as buying blind. The parts that made it onto this bike were selected after extensive research, including reading through large numbers of buyer reviews and checking how each component held up for other riders. That is the difference between a reliable budget build and a box of parts that never quite works.

A practical rule follows from this: only order components that already have a substantial review history and consistent feedback. A part with no reviews, or only a handful, is an experiment rather than a purchase. A bike shop may also be reluctant to assemble a build from customer-supplied parts, so being able to do the work yourself, or having a trusted mechanic, matters as much as the parts list.
What the Build Costs and How It Rides
The total came in between £1,500 and £2,000, closer to the lower end. For a bike with this silhouette and this level of equipment, that is a striking figure, and it is a long way from what a comparable build from a Western brand would cost. Weight sits at 7.4 kg with the other wheelset fitted.
Performance has backed up the numbers: five races on this bike, two wins and a second place, all at elite level. The aero package of frame, wheels, skin suit and aero socks is estimated to save around 50 watts in total, which is why this build feels faster than the lighter bike it replaced. The gain is more about aerodynamics than grams.
Overall Buying Advice
If you are considering a similar project, start with the parts that are hardest to get right: the frame, the groupset and the brakes. Each of the two components featured here has a clear case. The Sensah Empire groupset delivers light, race-proven shifting at a budget price, on the understanding that finishing and batch consistency vary. The replica EE brakes deliver most of the performance and a large weight saving for a fraction of the original price, with the caveat that they are not genuine parts.

Expect to spend real time on research before ordering, and expect to do some finishing work yourself, from clear coating to tidying up frame internals. With that effort, a build like this can compete far above its price point. If you want a bike that arrives finished and needs nothing, this route is not the one. If you enjoy the process and can verify the parts, the value is difficult to match.
Conclusion
Two components show why this build works: a budget groupset that shifts well enough to win elite races, and lightweight replica brakes that cut hundreds of grams for around £100. The rest of the bike, from the £800 aero frame to the 82 mm rear wheel and the narrow cockpit, follows the same logic. The savings are real, and so is the homework required to unlock them.
