From Sušice to the World Cup top 10: C/DURO’s 2026

Vojta Bláha finished the 2026 UCI Enduro World Cup 10th overall in the men’s elite standings. It is the result of two years of work between Vojta and the small team of CompoTech engineers in Sušice, Czech Republic, who design, wind and build every C/DURO frame.

He was 7th at Val di Fassa on 28 June, his first elite top 10, and 7th again at La Thuile a week later, 28.6s off the win. After six rounds, he finished the series 10th overall with 498 points.

Milan Čižinský, the designer behind the ShremeeQ’s lines,  also had success in the Masters category. He won the men’s 50–54 category at every UCI EDR masters race he entered in 2026: Loudenvielle, Val di Fassa and Aletsch, each by more than 90 seconds. At 52 he raced the same C/DURO bikes he helped shape, and his results are proof that the frames are clearly built for speed.

A race frame developed for the World Cup circuit

The ShremeeQ went on sale in January. Vojta had raced and tested the prototypes through the 2025 season, more than 600 hours of riding backed by telemetry, and he pushed them hard. In Finale Ligure he took a prototype rear end past its limit. The engineers then fitted strain gauges to the front triangle and sent him off test drops; his telemetry recorded 16G. The testing pointed to improvements in the head tube loop design, and together this work produced the two structural changes in the production frame: a single thicker ILT loop at the head tube in place of two thin ones, and a 3D-printed bottom bracket junction extended up to the main pivot to stiffen the drivetrain load path.

The frame runs 170mm or 190mm of rear travel on a high-pivot layout, so one chassis covers enduro and downhill. In April C/DURO released a 43-minute film of the development, narrated by Vojta and shot in the factory, around Sušice and in Finale Ligure.

E/Epona takes off

2026 is the year C/DURO’s first e-MTB really took off. The E/Epona was first shown at Eurobike 2025 and went on sale as a frameset that October; the first batch has now sold out, and it was reviewed this summer by Germany’s BIKE magazine, which found that it “excels in geometry, descending capability, and natural handling”. It puts a Maxon Air S motor (90Nm, 620W, 2kg) and a 400Wh down-tube battery into the Epona trail frame, with 150mm of rear travel and 29in wheels. A 3D-printed bottom bracket part carries both the main pivot and the motor, and the larger down tube makes the frame noticeably stiffer than the analogue Epona.

ShremeeG: the gearbox version

The newest member of the line-up is the ShremeeG, a ShremeeQ built around a Pinion C1.12 gearbox. C/DURO developed it with Vojta and Milan Čižinský on the same high-pivot Horst-link platform. Moving the drivetrain into the middle of the frame removes the rear mech and hanger, cuts unsprung weight and lets the rear suspension track the ground more freely. Riders first tried it at the May test days, before its public release. It is the first C/DURO frame in the brand’s new design language and is now open for orders.

Test days in Sušice

On 16–17 May C/DURO opened the factory in Sušice for its test days. This was not a car-park demo: riders met the designers and engineers, had their ShremeeQ, ShremeeG or E/Epona set up individually, then rode the local trails in small groups with Vojta and the C/DURO team, with a barbecue between rounds. For many it was the first chance to ride the ShremeeG and E/Epona before their public release. C/DURO’s own summary: “This is participation, not promotion.”

The rest of Vojta’s season

Vojta won the four-day Trans Azteca in Mexico in February. In March he climbed 8,852m in 24 hours on the ShremeeQ in Finale Ligure, riding the enduro trails down after every climb (watch the Everesting). In September he won his third Czech national enduro title at Kopřivná and the Czech Cup final at Králičák.

Built on CompoTech technology

Every C/DURO frame is made on CompoTech’s robotic winding cells, with tubes joined by Integrated Loop Technology. Load passes through continuous fibre loops rather than a bonded joint. We use the same tooling for aerospace, marine and industrial structures. A pro rider matters here: in one back-to-back strain-gauge session, Vojta put about 30% more load through the same frame than the engineer who rode it before him. A World Cup season is field evidence for that construction, not a substitute for laboratory testing, but it is evidence gathered under some of the hardest loads a frame can see.

Next

Vojta races the UCI Enduro World Championships in Finale Ligure on 16–18 October. The full line-up, ShremeeQ, ShremeeG, Epona and E/Epona, is available from cdurobikes.com, and Vojta’s racing and development videos are on his YouTube channel.

CompoTech developed and produces the wound carbon tubes with ILT joints for C/DURO frames. These developments are also used by customers in aerospace, marine, and industrial machinery. Enquiries: enquiry@compotech.com.
