They are super stiff and uncompromising in their approach to "get aero". To me a road bike is about speed. Endurance and Aero is mostly marketing. Unless you have special needs to ride rough roads or look hip buy the TCR. If anything you'll want to change the group set after 5 years rather than the frame, as GS tech is changing much faster than frames.
But road bikes change very little year to year compared to MTBs so people upgrade them less often. Disc brakes and electronic shifting are an attempt for the industry to generate more sales and turnover. Does the average rider need these? Personally, I'd get the Defy as I'd prefer a little more comfort over a very small increase in speed.
The current Defy frame is a new design and will be a bit more future proof. It gets very good reviews and provides better clearance for wider tyres.
But test ride them both and decide for yourself. And get a bike fit, best upgrade I ever did for my roadie. Mike95 Likes Dirt. Im on a Propel. Im lucky enough to be able to comfortably ride the propel with neg rise stem slammed with no spacers. Recommend going disc brakes if you can stretch the budget. I would rule out the TCR, I think you might find a refresh is due on that model.
He loves the defy, its his go to bike every time over the Propel, unless he is racing, or doing a really fast training ride. Before the Propel I was on a Scott Foil, another aero bike.
When I sold that, I spent 6 months without a real roadie, I used my Giant TCX cyclocross bike with road rubber on a 2nd set of 29er wheels. It was a great setup, I even raced it at A level club crit races until they called a stop to a few of us racing with disc brakes.
This bike now does most of my commuting duties fitted with some comfy x38 slicks. Haakon Call me Ken, whoreken. As has been said already, if you're not racing get the Defy. I'm a Defy Advanced Pro 2 owner, and I adore it. Disc brakes are a no brainer for any bike, and roadies are no exception.
I run 28mm tubeless tyres on mine and its a bloody brilliant bike on real roads with lumps and bumps. Get the best Defy you can afford - for 2 grand you might squeeze into the Advanced Pro frame the 2 like mine - I paid at Christmas. Calvin27 Eats Squid.
Both offer similar bikes and components in the same price range. Trek has a wider variety of bikes to choose from compared to Specialized. At entry-level, you get slightly better parts when you go with Specialized. You can certainly purchase bikes for less, especially if you get away from the name brands or are willing to take inferior parts. You want a more comfortable ride: A full-suspension mountain bike will soak up most of the jarring bumps that would otherwise be sent to your body and in some cases, buck you off your bike.
This can help reduce fatigue, which in turn can allow you to ride faster, for longer, with greater comfort. The hardtail was a winner on the rooty lap, being faster for less effort. The 'AR' any road models come with wide volume tyres and are disc brake only. Giant also produces 'SL' super light models which use a higher grade of aluminium, plus SL disc versions which come equipped with rotor stoppers that will work in all weathers. The Giant Defy is the brand's endurance road bike.
The aim of the game in its creation was to offer a comfortable ride that can be enjoyed all day long - even in the toughest of professional one-day classics - whilst still offering handling that feels fast and enough stiffness to provide quick acceleration.
A key technology used on the Defy bikes is 'D-Fuse' - this features at the seatpost and handlebars. Essentially the tubing is rounded at the front and flattened at the rear, to absorb shocks and vibrations for a smoother and more compliant ride feel.
All bikes in the range use disc brakes and wide volume tyres which add to comfort. The Giant Defy Advanced options feature an Advanced-Grade Composite frame, matching material at the fork along with an OverDrive steerer which promises front end stiffness and control.
Another nifty addition is the 'RideSense' monitor. The Liv women's bikes have an entirely independent geometry, built from conception around a female rider. However, the Liv Avail is available in aluminium and carbon versions and mirrors similar qualities of the Defy. Read our review of the Giant Defy Advanced 1. As its speedy sounding name may suggest, the Propel is the brand's aero road bike. And isn't it beautiful.
Giant Propel models received disc brakes for the first time in the range, six months after being first spotted at the Tour de France. The Giant Propel Disc uses flat-mount technology, thru-axles front and rear and Giant says that during aerodynamic testing its disc-brake integration produced less drag than traditional caliper brakes. Giant produces both rim and disc brake versions of its Propel models The basic Giant Propel Advanced 2 comes with an Advanced Grade Composite frame and the OverDrive 2 steerer for increased front-end stiffness and enhanced steering performance.
Moving on to the Giant Propel Advanced Pro range, these bikes come with deep section wheels and more integrated cable routing, alongside the OverDrive 2 steerer and 'RiseSense' capability. The Propel Advanced Disc comes with hydraulic stoppers, wider rim rear wheel and integrated bar and stem for the Propel Advanced 2 Disc.
Whilst the Liv women's bikes are not women's versions of the men's bikes, the Liv Enviliv is the aero road bike within the brand's range and shares many of its technologies with the Propel. The Giant TCR goes down in cycling history as an icon in its own right. It's an all-rounder race bike that's well renowned for offering significant stiffness and maintaining a notably low weight.
The frame now features flatback tube designs, particularly around the fork and headtube. Stiffness has also being increased, particularly in the downtube and bottom bracket area.
These models come with Advanced Grade Composite frames and the OverDrive steerer along with fairly basic wheelsets. This carbon rim wheelset comes shod with tubeless tyres in all cases, and they're genuinely impressive wheels, so none of this "great bike, needs new wheels" malarky that almost always adorns bike reviews.
These feature new ThinLine painting technology, which saves 65g in weight from paint alone. For women, Liv's lightweight racing bikes that are suitable for both long hilly road races and fast-paced crits are the Langma range. The Liv Langma tips the scales at 6. Giant's Trinity bike has been raced at the very top level and have been engineered using Giant's Computational Fluid Dynamics and dynamic wind-tunnel testing. The Trinity Advanced is the basic model and its tube shaping is designed to beat resistance and the brakes are hidden, whilst a standard stem means adjustability is kept high.
Even if you ignore the lack of disc brakes the bike frame looks different? Even if you ignore the lack of disc brakes the bike frame looks different. The beauty I reckon is in that compact shape which seems to give you that little more power without you realizing it. I think the main noticeable difference is just the headtube and stack height. There are other geo differences but thats the main one I found for me and had to space up the front end to lift the bars higher which kind of defeated the purpose a little to buying a TCR.
The Defy I reckon is massively underrated. Its a really fast bike just probably not as areo in the front end but as a reccy rider I might even go as far to say that the Defy is better for recreational weekend warriors over the TCR. To me though these two bikes are the best two bikes performance cost benefit wise you can buy. Edit: I haven't tried this yet but I bet if I slammed the stem on the Defy then I would get a very similar ride feel to a spaced up TCR the benefit of the TCR is that you can get in a lower riding position so depends a lot on your riding style.
I'm 6"4 on a large defy and there is about an inch of spacers under the stem which is in turn angled down. I could experiment with lowering the stem on the fork to see what a more TCR ride is like. Low handlebars I assume only really benefits weight on the front end and aerodynamics. I have no idea how to determine the correct bars height beyond going with what is comfortable.
I did try an alloy XL Defy but it felt way too long in the top tube, even with a shorter stem. Work on your core strength and it shouldn't be too far off. Disclaimer: I have no idea about bike fits, just noticing this is a "common" handlebar drop among the taller people in my group. Also try getting a wider range cassette say an and a powermeter. If you want to climb fast most would argue you've got to climb to power.
If you're just riding for fun a nice set of wheels would do or save the cash. Bike weight means bugger all compared to the fitness of the rider , having gears that you can comfortably spin in is much more important.
Just a little anecdote, I used to try and slim down to 54kg for racing, but I find I climb much faster at 58kg. Basically, don't diet yourself too heavily, just eat healthy, train and rest properly. Jump to. Who is online Users browsing this forum: No registered users.
