When I was younger, my parents had a boat. They sold it, eventually, having realised that the saying "a boat is a hole in the water surrounded by wood into which you pour money" has some grounding in truth. It's fair to say I followed in their footsteps with bikes, except I've not given up yet.
Bike riding can become an expensive hobby if you let it. It really doesn't have to be - you can have as much fun on a £1,000 road bike as on a £10,000 bike (see my review of the Ribble R872). But if you do decide you want to splash some cash on a few upgrades, there are some areas where the gain is much greater than others...
Where to spend
Looking to choose upgrades that will make a big difference? These are the ones we would recommend.
It is better to buy one bike frame and have it last you a decade or more than it is to buy a new bike every three years - both from a pocket orientated and sustainability perspective.
Investing in your frame doesn't necessarily mean buying the latest and greatest. Make sure you're choosing a frame with geometry that suits you. Look for 'standard' standards, too - a lot of frames with proprietary components promise aero savings but you're stuffed if you want to replace the seat post only to find it's out of production.
The surest bet here? Find a frame builder you trust and buy a custom frame. The time investment is much greater, and the cost will be higher than buying an entry-level frame from a big player - but shop around and custom frames don't have to be more expensive than mid-range off-the-peg options. In 2018 I had a custom Werking frame built, the RRP sat at £3,500; I have never felt such an affinity with a bunch of carbon tubes as I did when riding that bike. Custom geo on an Isen steel bike adds just £380, with frames from £1999. Going custom means you're far more likely to be entirely satisfied with the result - greatly reducing the chance of a trade in a few short years down the line.
Finally, if you're going to invest in a dream frame, it might be worth adding one more little extra hurdle en route to perfection by getting it faced before you build it up. Your components may thank you.
Assuming you're riding on a smooth, flat piece of road at 40kph, rolling resistance makes up about 20 per cent of the total energy you're putting into the bike. The rest is accounted for by aerodynamic drag (70 per cent most of which is you) and drive train friction (10 per cent). On rougher surfaces, rolling resistance has an even greater impact.
Your tyres also play a pivotal role in rolling resistance, as well as comfort. More supple compounds smooth out the bumps below you and offering more grip in the corners.
Aeightbike's Glen Whittington has worked in multiple workshops, and has been the mechanic to several pro teams. He put tyres high up on the 'spend' agenda, as well as a consideration for what's inside them: "For me, the very first thing I would consider is tyres, but also tubes and tubeless. A supple tyre will pay you back a million times over as it reacts quickly to the ground beneath you to improve comfort, speed and grip. Ask any proper crit racer if they'd like more front end grip or a lighter bike and they'll pick grip, every time.
"Don't forget about tubes - the best tyre needs to deform and reshape itself thousands of times a minute, butyl tubes create friction between the tyre and the tube and at high pressure they don't allow the tyre to deform and move around - the new generation of lightweight and latex tubes reduce this issue and save considerable rotational weight - even better go tubeless and completely remove the problem."
Tyres do contribute a fair amount towards a bike's overall weight. The Continental Grand Sport Race (£30 per tyre/£60 per bike) is a fairly common stock tyre, and a 28mm model has a claimed weight of 330g, whilst the Grand Prix 5000 (clincher) comes in at 235g (£60 per tyre/£120 per bike) in the same width. "Once you've experienced lightweight tyres you won't go back," Whittington said.
Many bikes retailing below £2,500 come with entry-level stock wheels, and all of our Cycling Weekly testers will confirm that swapping these can drastically improve ride quality.
However, this is an area where there is a very clear point of diminishing returns. It can be tempting to build up a 'wheel library' of hoops for all occasions, but we'd advise most riders to find a middle ground and stick with it.
Starting with rim depth, Parcours' Dov Tate has completed extensive testing and found that the difference between a box section alloy rim and a 40mm Parcours Grimpeur wheelset comes in at 22.9 watts, all things being equal when running the Chrono 77mm front/86mm rear pair the gain is 29.7 watts. So - there is a big gain to be had by upgrading from a box section to mid-section rims - but the benefit of going deeper sits at around 6 watts.
Similarly, a super lightweight wheel will feel amazing, but the actual increase in speed is questionable, "if you run the numbers you literally have to climb Alpe d’Huez or equivalent before weight becomes more important [than aerodynamics],” Tate told us.
The 'middle ground for most' viewpoint is one that Aero Lead and Senior R+D Engineer at Specialized, Mio Suzuki shared, telling us: “Having evaluated many leading brands’ wheels and having designed some in my bike-industry career, my recommendation for performance or race-focused consumers would be 40mm-50mm wheels. But, if a consumer is weight conscious, and doesn’t like the feel of handling the deeper rim wheels, then 32mm is a good choice.”
When it comes down to how much to spend - there are some excellent options around the £1000 mark, the Parcours' Strade being a good example.
Whittington is all for finding a local wheel builder, adding: "If you want a really nice set of handbuilts expect to pay around £600-£800, and then the next step up would be a carbon wheel. Carbon wheels again aren't specifically aimed at being lighter, it's much more about better aerodynamics, so don't be put off by a wheel that is fractionally (50/100g) heavier if it's superior in terms of aerodynamics."
A lot of work (some of it not entirely successful) has gone into creating flex at the seatpost in recent years. That's because whilst brands are still chasing the superlative in stiffness when it comes to the areas of the frame which flex under load, riders need compliance or fatigue will set in before they've had a chance to make the most of that awesome power transfer. The seatpost (alongside tyres) is one area where comfort can be maximised without sacrificing frame stiffness.
Directly comparable data is frustratingly hard to come by without employing an external testing facility or investing in some equipment most magazines don't have. However, countless tests have shown that carbon seatposts provide greater deflection and vibration dampening when compared with aluminum options, and that you'll get a lot more flex here than you ever will out of a frame.
"A carbon seatpost is definitely a worthwhile investment - anyone looking to ride a 100 miles or more will not regret it," Whittington reported. "The flex in the seatpost has allowed frame builders of all kinds to vastly improve the efficiency of the drivetrain without sacrificing the rider comfort by isolating the two things from one another."
"One of the best ways to make a rider faster on a descent is to give them better brakes" - the guy in a local bike shop I used about 10 years ago. I'm sure this quote is not unique to said bike shop owner, and that's because it's very true.
"The techy reason why [quality brakes are so] important is if you can apply more brake power for a shorter time, and modulate that power, then you'll cover the ground more quickly," Whittington says. "Probably the more important reason is that better brakes will improve your confidence as a rider - without knowing why you'll get faster and faster because you're more confident about what your bike can handle, and if you need to get out of trouble, you won't already be on the limit."
"I haven't really used anything less than [Shimao] 105 for a long time now - anything from that pricepoint upwards will certainly improve a budget bike."
If you want to really maximise performance, check out some of the upgrades available from brands like Hope. At last test we awarded the RX4 a perfect 10/10. This features a four piston design as opposed to the usual two, and machining the caliper from a single billet of aluminium reportedly makes for a lighter and stiffer product.
This doesn't just apply to the caliper (rim or disc), but the pads also. The last time I tested a bike that came specced with a Shimano Tiagra non-cartridge shoe/pad combination, I swapped these for a Shimano Ultegra shoe and pad - the outlay was £46 but I found this resulted in a dramatic drop in braking distance.
Whilst we're on the groupset topic, Whittingham advocates checking out your crankset - and its overall weight: "One note that I'd add is to consider the cranks - I was surprised when I tested a few out just how much perceived difference it makes, how much actual efficiency improved and how much weight could be saved - I swapped the bog standard Shimano OE cranks for SRAM Red 1x and saved nearly 400 grams. It also vastly transformed the experience of riding the bike. I'd say it's as important as brakes, but not quite as critical as wheels and tyres."
Where to save
Now, if you've made these investments - then there's no judgment here, whatsoever. CW's tech team members have no doubt made some of them, too. It's not that we don't enjoy the benefits of these lovely luxuries, we just don't think they're quite as bang for buck.
Handlebars and stems
Carbon handlebars can come in anywhere from 20 to 40 per cent lighter than their aluminum counterparts. Carbon is also more malleable and can be contorted into some inspired wind defeating shapes.
However, the weight difference is minimal and the actual aero saving is questionable. It's arguable that the price difference is disproportionate. An alloy set of bars will cost you £55, vs £250 plus for carbon.
In terms of drag, in a bike/rider unit, the rider makes up in the region of 85 per cent of drag. This can be reduced by narrowing your frontal area - but the cheapest set of aluminum handlebars can do this job provided they're available in the correct size.
“The rider is and always will be the biggest contributor to overall system drag. And the easiest thing a rider can do to reduce drag is reduce their frontal area… Next to rider position, the wheels make the biggest difference in reducing system drag,” Cervelo’s brand manager, Anton Petrov told us.
When working at the Boardman Performance Centre, Head of Science and Tech Development Jamie Pringe told us that the degree to which the aerodynamics of the bike's frame and component profiles matter comes down in part to how optimised the rider is themselves.
“Take a road rider and bike combined, in fairly average and typically unaerodynamic road position. The overall CdA will be high, and bike itself may be only 15 per cent of the total drag,” Pringle told us. “But for the road rider with a well-optimised position, their overall CdA is much lower – but the equipment itself hasn’t changed, so that bike can become 20 per cent of the total system drag" - that percentage increases when we begin to look at already optimised time trial riders.
So, if you've exhausted all avenues in terms of how to reduce your own profile, aero frames and bars will become of higher importance, until then, there may be cheaper savings to be had elsewhere.
Super lightweight components
There are some jaw-droppingly light components available on the market. A prime example is the Selle Italia SLR C59 saddle - which weighs in at just 63g, but will set you back £449. Unless the feathery caress of carbon across your entire undercarriage is particularly high on your wish list, this one falls into the marginal gains category for us.
Carbon railed saddles, even, hike the price - as an example, the Fizik Luce saddle with alloy rails costs £89.99 vs £164.99 for the carbon option. The weight difference is 56g, so it's not quite as expensive per gram as carbon handlebars, but if you intend to enter into a process of saddle trial and error then the cost will add up. Getting a saddle that suits your physiology is essential to efficient power transfer - we'd always recommend prioritizing finding a shape that works for you over low weight.
Lightweight bottle cages come into this category, too. I'll admit to sporting two Cinelli Mike Ram carbon cages, coming in at £100 for the pair, on my own bike - but the reasoning is entirely aesthetic; a £2.99 cage would suffice. Upgrade pedals also sit in this category; many top end pedals use the same system as their cheaper counterparts whislt the difference in material, which hikes the price, is barely discernable.
The moving parts of your bike are full of bearings. Traditionally, these will be made up of steel balls within a metal race. However, it is possible to upgrade to hybrid bearings that use ceramic balls and a metal race, or full ceramic bearings with ceramic races.
According to market leader CeramicSpeed, if you upgrade to ceramic bearings in your hubs, pulley wheels and bottom bracket, its tests show you'll gain "6-9 watts, compared to using standard bearings." You can then fit your bike with a CeramicSpeed UFO Racing chain, and "save between 2–5 watts, taking your competitive advantage up to 14 watts."
Many oversized pulley wheel systems use ceramic bearings. As well as looking cool at the coffee stop these reportedly provide a saving of around 3 watts, due to the greater efficiency in pulling the chain around a larger wheel.
In total, that's 17 watts - assuming everything is running smoothly and well maintained. It's not a saving to be sniffed at, but the costs add up.
"I really do rate ceramic bearings, but it's a huge investment," Whittington told me, "I would look at it as your final investments rather than the place to start. To get the best advantage you really need to replace all six hub bearings, the BB bearings, the pulley wheel bearings and the chain, which can easily set you back £1500. For that kind of money, you could buy a very nice set of wheels."
Looking for cheaper wins? CeramicSpeed's own data shows that at 250 watts, a cleaned and lubricated chain will save 4 watts, a further 3 watts can come from avoiding cross chaining whilst the cost of a worn chain is about 2 watts.
Lekky gears are indeed very nice to have, and we would rather ride them over mechanical. The shifts are smooth and seamless, there's never a clunk to be heard and the hoods are slighter and more ergonomic, particularly for riders of a smaller build.
However, as long as the cost of a replacement rear mech stays elevated, most of CW's tech team writers will be sticking with mechanical on our own personal builds. Of course, the prices come down as you move through the ranks, but the RRP on SRAM's new eTap AXS max rear derailleur - as an example - is £610/$710. Not including the battery, which is a lot for a component that is quite so vulnerable to damage.
Bike fits (to an extent)
Being comfortable and efficient on your bike is crucial to your enjoyment and performance, and often having a qualified professional help you to achieve this can result in massive gains. That matter is not in dispute. However, do shop around.
Expensive bike fits, coming in around £400+, will often be accompanied by the use of fancy lasers and video analysis. These tools can help reassure the customer that they are in the right position once they leave the premises, and granted they are often used by practitioners of fit with excellent knowledge. However, there are many exceptional fitters working in bike shops across the country and charging a lot less. Don't overlook an experienced bike fitter just because they can't promise you a laser show.
