At road.cc every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.What the road.cc scores mean
Good scores are more common than bad, because fortunately good products are more common than bad.
If you are a fan of a rim-braked aluminium racer that is tight, nimble and just on the right side of stiff so as not to shake your fillings out, then you are in luck. New kid on the block Tresca has delivered exactly that with its first model, the TCA-1. With steering that'll give you whiplash if you push it to its limits, this thing is a grin-inducing speed machine that'll brighten up your day, whether you're out for a quick blast or taking things easier covering a century, though still at a decent lick.
I've been riding road bikes for pretty much 20 years now, and while the technology has improved massively in that time, with electronic shifting, disc brakes and carbon fibre left, right and centre, I got hooked on riding because of bikes like this.
The highlight of the Tresca for me is the handling. It's quick but perfectly weighted and balanced, allowing you to really explore your limits.
If you are a timid descender you might find it a little twitchy unless you relax and let the bike do its thing, but if you are one of those riders who's confident in their own ability and kind of thinks, 'F**k it, I'll just see how fast I can take that bend,' then you are in for a treat.
I kept chucking the Tresca down my local technical descents and I couldn't fault the way it carved its way from apex to apex, even with the camber shifting to upset the weight.
I had some close calls, finding the grip limits of the tyres, but the amount of feedback you get back from the frame and fork allows you to control the slide or shift your bodyweight to get things back under control pretty easily. Basically, it's an absolute hoot.
Calming things down a little, the TCA-1 is a fun bike to ride at a more sensible pace too. I did a couple of 100-mile rides aboard it – you can still have some fun in the twisty bits, but elsewhere I could just knock things back a touch and tap out the miles without really thinking about it.
The Tresca doesn't have the most refined frame out there when it comes to comfort (it actually reminds me of Cannondale's CAAD 10, a little bit old school) but even with the bit of buzziness from the road I wouldn't say it is harsh – far from it, in fact.
Aluminium has come a long way in terms of finding a good balance of stiffness versus ride quality, and the Tresca is a good example of that, if not quite up there with the Specialized Allez Sprint Comp or my benchmark, the Bowman Palace:R. I'd finish longer jaunts knowing that I'd done a decent ride but without exactly feeling broken, especially in the upper body where it is often more evident.
This Shimano 105 build comes in at 8.03kg (17.7lb), which is a pretty decent weight, and it feels it out on the road. Acceleration and climbing are achieved with little fuss, and it was a joy to take the Tresca into the hills. I'm not a climber by any stretch of the imagination, but I enjoyed tackling hills on the TCA-1. Thanks to its stiffness and weight, it gives a lot back on the climbs; if you get out of the saddle and give it the beans you're rewarded with eager-feeling forward propulsion. The stiffness means you don't feel like you are wasting any effort, it responds well to really hard efforts out of the saddle.
I'd sum the ride up as focused on speed and performance but without sacrificing all-round usability.
The team behind Tresca have designed the TCA-1 from the ground up, starting from basic sketches through to 3D modelling, using various computer programs to calculate forces and loadings through the frame and fork before even starting to create real world prototypes.
Setting a target of a sub-£1,000 retail cost for the frameset, Tresca decided that aluminium alloy would be the best option, concluding that creating a 'great aluminium frame could be vastly superior to a lower-end carbon frame'. A comment I would definitely go along with.
There has been a lot of development involved, with the 6066 grade alloy material being butted to create variable wall thicknesses and hydroformed to create the kind of tube profiles only achievable with the use of carbon a few years ago.
Up at the front you get a tapered head tube, with a 1 1/8in upper bearing increasing to a 1 1/2in at the fork end. It's something we see a lot and brings extra stiffness to the front end to deal with steering and braking loads.
It all works as the handling is absolutely spot on, with the full-carbon fibre fork matching up to the stiffness of the frame at the front end.
Like most performance bikes, the TCA-1 follows a common theme of being oversized at the business end of the frame: the down tube, bottom bracket area and chainstays.
The down tube increases in size from top to bottom, as does the seat tube with its flared bottom section where it meets the bottom bracket shell. Tresca has done this to give a much larger cross-sectional weld area at the part of the frameset that is going to see huge loads transferred to it from your pedalling action.
Bowman's Palace:R does something similar, and I first saw it on the original Kinesis Aithein, although that was only on the drive side of the seat tube.
Original designs of the TCA-1 were going down the BB30 route, but with the number of tolerance issues causing BB30 bikes to creak at the bottom bracket, a decision was made to go for a standard threaded bottom bracket instead; given the UK weather, it's the better option in my opinion.
To increase comfort at probably one of the most important contact points – the saddle – Tresca has designed the seat tube to work with a 25.4mm diameter seatpost, the idea being that the smaller than typical diameter allows more flex. In the real world, the 1.8mm difference over that of a more common 27.2mm seatpost will be negligible, to be honest, and will do little to offset the stiffness of the frame. Tresca has dropped the seatstays a touch, too, to promote comfort here.
It's good to see that the TCA-1 has full internal cable routing from front to rear, something that isn't always achievable with thin aluminium tube walls, and it certainly doesn't feel like removing the material has had a detrimental effect on the stiffness of the chainstays.
This is a race bike so you won't find – or need – mounts for mudguards or racks, so all you get is a couple of bottle cage mounting points, keeping everything clean and simple.
Sizing-wise there are just three options in the range: small, medium and large, with top tube lengths of 528mm, 547mm and 569mm. Tresca has used the stack and reach measurements to develop the geometry, so you'll find the frames remain in proportion as they increase in size.
This medium has a stack of 552mm and a reach of 387mm, which gives an aggressive ratio of 1.42, planting it, as if we didn't already know, fully in the race category.
A short 978mm wheelbase keeps the bike tight and flickable, while a seat angle of 73.8 degrees puts you in a forward pedalling position.
The front end is pretty steep too, with the 72.9-degree head angle giving you the quick steering I mentioned earlier.
Overall quality and finish is pretty decent. The welding is tidy and it needs to be really, with nowhere to hide on the lower half of the frame. The raw finish won't be for everyone, but it certainly makes the bike stand out in a crowd.
The Tresca is available as a frameset-only or in one of three builds, of which we have the entry level here: Shimano 105. You can also get an Ultegra or Dura-Ace model.
This is a very good specification and makes you think it's been put together by a bike rider rather than an accounts department because there are no hidden cheaper parts chucked into the mix.
As we've said countless times before, Shimano's latest R7000 is pretty much the best bang for buck groupset out there. Dave's review pretty much sums it up, but in a nutshell the shifting is awesome, being barely any different to that of Ultegra, as are the rim brakes, with loads of power and plenty of modulation. I'm also a big fan of the latest shaped brake levers.
Gearing-wise Tresca has given the TCA-1 the sensible option of a 52/36-tooth chainset and an 11-28t cassette. It covers all the gears you'll need at both ends for racing or just riding fast, to be honest, especially taking into account the light weight of the overall bike.
The handlebar and stem are from Fizik's catalogue, the alloy Cyrano R5 range, and it's quality stuff. It looks the business and offers plenty of overall stiffness.
The bar is also wrapped in Fizik's Microtex SuperLight tape, which offers plenty of cushioning without being bulky.
The seatpost is an FSA SL-K carbon fibre model which again brings a bit of class. Atop that we're back to Fizik once again and its Antares R5 Kium, one of my favourite all-round saddles.
Tresca has played a blinder with the wheel choice, too: DT Swiss P 1800 Spline 23s are great all-rounders, and while you may fancy something a little more aero or lighter for racing, these will make a great training set of wheels or for fast group rides.
With their 23mm-deep rim they weigh around 1,600g for the set, and I can vouch for their ability to stand up to plenty of abuse as I owned a set for a couple of years.
Tyre-wise, the TCA-1 is shod with Continental's mid-level Grand Sport in a 25mm width. They aren't the fastest rolling or grippiest out there, but for all aspects of road riding they can't really be faulted. I've ridden them on countless test bikes over the years and they are pretty robust, shrugging off cuts and punctures well, even in the wet.
If you are racing or just want ultimate performance then upgrade to something a bit lighter, but straight out of the box they are a decent choice.
The Tresca will cost you £1,600 for this Shimano 105 build, which I'd say isn't bad at all, but let's take a look at the opposition.
What about the two I've mentioned already, the Bowman Palace:R and the Specialized Allez Comp Sprint? The Bowman is available as a frameset only and will set you back £745, which is quite a chunk less than the Tresca's £850, and as I've said the Palace:R is still my benchmark.
Against the Allez, though, it fares a little better. The Specialized has a very similar build but is finished with own brand components for the cockpit and seating arrangements while costing £1,700.
Weight is negligible between the two, but one thing you have to remember is that Tresca is a small direct-sales bike company taking on the huge buying power of one of the largest makers in the business, and it still comes in 100 notes cheaper.
Canyon does offer the Endurace AL 8.0 for a very impressive £1,179 with a full Ultegra groupset (I tested the 7.0 disc version here). You are getting basic wheels and finishing kit with the Canyon, though, and more relaxed geometry.
A Cannondale CAAD 12 105 will set you back £1,500, although I'm yet to ride one so I can't give much feedback on how it responds.
To sum it up, I think the Tresca TCA-1 is a great bike to ride; it's heavily influenced by the engineering angle but that, thankfully, hasn't destroyed the fun factor.
A vibrant, quick-handling and stiff race machine that responds brilliantly in the bends

With 20 years of road cycling and over 150,000 miles in his legs it's safe to say Stu is happiest when on the bike whatever the weather. Since writing his first review for road.cc back in 2009 he has also had a career in engineering including 3D-CAD design and product development, so has a real passion for all of the latest technology coming through in the industry but is also a sucker for a classic steel frame, skinny tyres, rim brakes and a damn good paintjob.
His fascination with gravel bikes is getting out of control too!
