I do not ride competitively, but plan on doing some longer distance rides (+30 miles). I've read that better components are lighter, run more smoothly, and last longer. Out of those three categories, durability (lasting longer) is the only one that really matters for me, as long as the components don't break all the time and get the job done. Are the main advantages of high end components the reduced weight and smoother operation, or are they significantly more durable as well?

    You want stuff that durable and trouble-free. I don't keep up with the various component brands/families, but there's no need to spend more than about $1500 for the complete bicycle. – Daniel R Hicks Jun 18 '13 at 20:31
  • Could you clarify what you mean by "better components"? We might be able to give you slightly more helpful answers if you clarify which group sets you're comparing. For example, a comparison between Sora and Tiagra is very different than a comparison between Ultegra and Dura Ace. – amcnabb Jun 18 '13 at 21:38
  • If you're talking 30+ miles then you might want to move weight a bit higher up the priority list, especially if you live somewhere hilly. A lighter bike will use up less of your energy reserves over the same distance compared to a heavier bike, and heavy bikes can really be unpleasant to pedal up hill. – GordonM Jun 24 '13 at 22:59

I assume that you're talking about road biking. I can give you my opinion after using these groups for a while: Shimano Sora, Shimano Tiagra, Shimano 105, and now a full Shimano Ultegra.

All work, when properly adjusted and when shifting correctly. You have to do your homework and know how to shift smoothly, and adjust the gears. Whoever tells you that something is "not good" or "does not work" is lying or wants you to expend money. But of course different levels are there for a reason:

Weight: More expensive is lighter. Stiffness: More expensive is stiffer, therefore transmitting your power better without loss of energy. Ergonomics: More expensive groups tend to have a refined shape. Reliability: More expensive groups tend to stay tuned longer than less expensive ones. Shifting under pressure or more than one gear at the time: Expensive groups allow you to do it, cheaper ones don't. Smoothness and speed: Shifting is faster and smoother on expensive groups.

If you notice, I put smoothness and speed last. It is usually one of the reasons that people mention as being key, but in my experience proper adjustment and proper shifting technique are more important than the group. My bike with Sora/Tiagra shifts as smoothly as the Ultegra after adjustment. But the other reasons are important to many people. Even if they don't compete they may want a light, stiff, and reliable group that makes the experience of biking more pleasurable (although the real pleasure is riding, of course), and they are willing to pay for it. They are undoubtedly "nicer".

Regarding durability, I'm skeptical about people's comments. Most of the times people change chains and cassettes because they are worn out, and upgrades/changes the rest of the group's components as new models appear, not necessarily because they don't "last". If you're a recreational rider, whatever you buy will "last" more than you will need. I've seen 20 yr-old bikes that work perfectly, provided that the user changed the chain and cassette regularly. But remember durability and reliability are two different things.

At which point is not worth expending more money? Difficult to tell, but here is my suggestion (take it as a suggestion and nothing more):

Dura Ace or Sram Red if you compete. Ultegra or Sram Force if you are an enthusiast that races or values to have a performance group. 105 or Sram Rival if you want a very nice recreational group. Tiagra or Sram Apex if you want a solid recreational group. Sora and below if you are a recreational rider that does not want to spend too much money.

EDIT: I recently had the luxury of trying a bike with electronic shifting (a Shimano Ultegra Di2) and I would like to add to my answer that in this case, the hype is true. It is a true revolutionary thing. Expensive, very expensive. Worth it? Probably not. But really good, yes.

    +1 for some very good points, though I'm not quite convinced that you can separate durability and reliability. Non-durable parts seem to show it by quickly becoming unreliable. – amcnabb Jun 19 '13 at 23:14
  • It is my experience that all groups last thousands of kilometers before needing to be changed, plenty for a recreational rider. But it is my experience too that groups tend to loose adjustment after only hundreds of kilometers, specially the low-end ones. Hence I separate them, admittedly somewhat arbitrarily. – J.

    I would argue that Ultegra and Force are intended/geared more towards racing cyclists than enthusiast riders who race. – Altom Aug 18 '16 at 14:26

Here's a little bit of information that's in contradiction to "higher end equals better" Lower end components can sometimes last longer and be less problematic than the higher end components. In order to shave off every single gram they sometimes have to skimp on materials. Also, the tolerances are much tighter, and high end components can often be difficult to tune because fractions of a millimeter matter. An 8 speed derailleur can be quite a bit out of tune before you'd notice. The same can't be said for a 10 speed. With so many gears, there's very little room for error. 10 speed chains are thinner, and therefore stretch and break more.

Don't go for very low end stuff, because it often will be made bad, and will break faster. But different components are built with different goals in mind. Very high end parts are often built for racers, who have professional mechanics who can ensure that everything is tuned properly, and parts are replaced more frequently. If you buy decent components and maintain them well, you'll get plenty of life out of them, and you'll be able to replace them when it's necessary, instead of waiting until it's too late.

    Great answer. Specifically (for road) I would go with Force or Ultegra (or even Apex or 105) for the shifters and derailleurs. Then finish it with a nice long lasting cassette and chain (the race cassettes and chains are the bits the REALLY don't last long). – Ken Hiatt Jun 18 '13 at 21:28
  • 2
    @KenHiatt Not to put words in Kibbee's mouth, but he seemed to be referring to 8-speed components, which would be sub-Tiagra. I guess "lower-end" and "higher-end" aren't very specific terms. :) – amcnabb Jun 18 '13 at 21:36
  • Yeah, I think that road bike have a little problem where even the "lower end" stuff has a 10 speed cassette, where they probably could have delivered a much better component for the same price by going with an 8 speed cassette. Most people buying lower end bikes would probably appreciate the added durability and not needing to have the bike in such good tune at the expense of having a little more spacing between the gears. It's much more common to see 8 speed cassettes on mountain bikes, even though they probably have more gear range within the cassette. – Kibbee Jun 18 '13 at 23:00

    For someone asking about 'increasing to 30 mile" rides - Ultegra is way OTT. For years 105 (road) and XT (MTB) have been considered the entry level for Competitive riders. Higher is for sponsored riders, lower for weekend warriors - an I know of weekend warriors who happily put in 100miles+ on Tiagra – mattnz Jun 19 '13 at 1:50
  • @mattnz Quite true... I've racked up about 50,000 km on my road bike over 4 years, riding 100-200 km at a time fairly routinely. It has a Tiagra groupset, and I've never wanted to change it. – Will Vousden Dec 15 '16 at 11:23

This very much depends on how exactly you define the classes of components and what type of riding you plan on doing. The definitions are not standardized, but component ranges from each manufacturer are easily ranked. The following are the MSRP of complete group sets for Shimano (the price ranges are similar for other manufacturers).

  • Dura Ace 9000: $2699.92 (high-end)
  • Ultegra 6800: $1249.92 (mid-high)
  • 105 5700: $1024.85 (mid-range)
  • Tiagra (mid-low)
  • Sora (low-end)
  • non-series (very low-end)

If you truly only care about durability and don't care about either weight or smoothness of operation, then you will probably find that mid-range components are a better value for you than high-end components. Even if high-end components (e.g., Dura Ace) turn out to be more durable than mid-range components (e.g., Ultegra, 105, maybe Tiagra), this would probably not justify the more-than-double cost if the only thing you care about is durability. If you had to replace every part, you would still come out ahead in terms of dollars spent.

Mid-range components (e.g., 105, Tiagra) are far more durable than low-end components (e.g., Sora, non-series). Any but the most undedicated rider can appreciate the benefits of mid-range over low-end components. I personally bought a used bike with Ultegra that cost about the same as a new bike with Sora, and I feel like I would be wasting my money to get a bike with Sora.

From how you describe your riding, it sounds like you would probably find the best value from mid-low to mid-range components, but this completely depends on the degree to which you are constrained by cost. Because more expensive components can sometimes be less durable than cheaper components, it is too easy to be dismissive and assume that the high-end components are Veblen goods (see The Online Photographer for a discussion related to photography equipment, a similar market).

One person can't say whether a product's price is "worth it" to someone with a completely different income and lifestyle. I once talked to someone who owned "Lance Armstrong's bike" (after I asked, it turns out it was the same model, not a collector's item), which was an example of the 'high status of allegedly "pro" products among amateurs'. But this person was happy with his bike and seemed to be at least somewhat appreciative of its benefits over a low-end bicycle. Few cycling products qualify as Veblen goods:

[With bikes], there's not an inverse relationship between cost and durability, like there is with other items like clothing. A $40 pair of jeans will be vastly more durable than a $2,000 dress, but a $2,000 bike will probably be far tougher than a $100 Wal-Mart special. That's because bikes are built to be ridden. Race bikes are built to withstand the rigors of competitive use. Yes, there are exceptions--plenty of campanies make ultra-lightweight frames, wheels, tires, etc. that are intended for specific events only and will not stand up to everyday use. But generally speaking, this stuff is meant to be used. (Bike Snob)

In the end, each person must decide what they need and are willing to pay and whether a product provides benefits that they will appreciate. Don't jump to the assumption that other non-competitive riders are wasting their money on expensive crap, but also don't feel guilty if you don't notice or appreciate the difference in weight between two bikes. And if you end up doing longer or steeper rides, you can always change your mind later.

  • To further your use of the Shimano groupsets, I would say you could certainly go further down at least one level (to Tiagra), possibly two levels (to Sora), and possibly further (don't know), before you come to a point where you look at the components and you might say, "that level of quality isn't good enough". – PeteH Jun 18 '13 at 20:30
  • @PeteH, I test-rode a bike with Sora, and the shifters felt really flimsy. I would be inclined to lump it into the low-end/scary category, but I haven't actually owned it. – amcnabb Jun 18 '13 at 20:43
  • @PeteH I looked for MSRP for the full Tiagra group set to add to my list, but the numbers are hard to find. Feel free to edit it the prices in if you can find them. – amcnabb Jun 18 '13 at 20:48

    I also test rode Sora and would tend to agree. My audax/touring bike however has a Tiagra groupset and this is perfectly useable. Nowhere near as nice a ride as my carbon/ultegra ride but a fraction of the price. Had a quick look on a uk site and tiagra comes in at about 75% of the 105, Sora at about 50% of the 105. – PeteH Jun 18 '13 at 21:16

    My first bike had a Sora group set which I later upgraded to Ultegra (all except the bottom bracket and crank set). The difference in smoothness was remarkable and well worth the cost. +1 for the mid-range advice. – Carey Gregory Jun 18 '13 at 23:53

If on a road bike anything that is Sora / 105 level will work wonders. Deore or similar will work fine.

What is more important that the group-set IMO is the general quality of the cranks and chain-rings. The better the forging the longer they last.

TBH I don't think it really matters once you get to decently specced bike these days because modern chains and chain sets are so good that they run years with few problems. I have a Sora kit that has almost zero maintenance for several years and the large chain ring is starting to want replacement just now.

Also It matters how it feels a lot as well. Crappy pedals and cranks will make it feel like you power transfer isn't brilliant; even the pressure in the tyres affects how I feel when I ride.

I think tbh there is a lot of focus put on one part of the bike, yes crappy shifting can ruin riding but also having a crap set of cranks or wheels also hurts just as much.

Cycling as an enjoyment can be fulfilled on any bicycle as long as you enjoy cycling.

In my younger years I achieved a resting heart of 33 BPM riding an aluminum series 7005 generic racer at a cost of £300.00.

I still have this bicycle, most of the running gear has been replaced recently for Shimano Ultegra and Campagnolo Zonda wheels.

I'm in my early fifties, my right femur is 4cm short due to a motorcycle accident nearly thirty years ago. I now run a 28 tooth front ring due to knee issues.

Lets be honest, aluminum, steel,titanium or carbon does it really matter. I do realize reasonable specked components do make a noticeable difference to riding quality.

It's a person desire for cycling that inspires their performance.

For those at the higher pinnacle of cycling who race professionally where crucial seconds matter only the best components will do.

I may not be riding the latest carbon frame but I do enjoy riding the bike I have.

There's a lot of personal preference here, but here is mine. I ride 250 mi/week. I like Ultegra a lot except for the chain & derailleurs. The difference between Ultegra and Dura Ace (I own both) is minor for durability. My Ultegra bike still has the original components after 15,000 miles (5000 30 mile rides), with the exception of Dura Ace chain, and derailleurs. The DA chain seems good for about 2500-3000 miles, and the Ultegra rear derailleur main spring got weak after about 6000 miles. I smashed the front derailleur with my shoe at about 5000 miles. The Latest Dura Ace chain is awesome shifting and cheaper than the old one. It will improve Ultegra shifting. With the DA derailleurs, your shifting and stiffness will match a full DA bike. Ultegra cranks(stiffer), brakes, and cassettes are more durable than DA, but heavier. Lots of sites have this weight data, but most recreational riders could care less. The latest Shimano 105 is impressive too, but the extra cost for Ultegra is very small, so why not? Also, right now the DA 9000 derailleurs are pretty cheap as the new 9100 is coming out. My big chainring is also about to need replacement.

  • 5000 30-mile rides is 150000 miles, not 15000. – David Richerby Oct 15 '16 at 19:10
