Are You a Weight Weenie?

Updated 01 October 2017

Are you a weight weenie? Google defines it as "A cyclist that is concerned about the weight of his or her bicycle." But I feel that this definition is not strong at all, it fails to capture the single-minded, relentless pursuit of bicycle weight loss. As found elsewhere on bike forums, the definition below captures the essential meaning of a weight weenie much better.

"A true weight weenie is one who can't sleep at night thinking about his next upgrade and all the possibilities for grams to be shaved-off. When the dream eventually becomes a reality, the process is again repeated."

I couldn't have said it better! Many cyclists like to upgrade components in order to save weight, believing that it will make them go faster. Whether it is really true or not, I am not sure. Even if you do go a bit faster, the gain is probably miniscule compared to the total time. The majority of the weight actually comes from the rider, so losing weight off the rider is probably more effective (but harder!)

I have gone through many many different bike components for all the bikes that I have upgraded. Along the way, I have actually kept a pretty good record of the component weights! Initially it was only meant for my own reference, to see if a new component is really as light as the manufacturer claims to be. But the database expanded and expanded, and I have the weights of most components that have come into contact with the bikes.

Want to know the weight of all these components? Read on to find out!

Before you get too excited, take note that some of these component weights were measured using a luggage scale, while others are measured using a digital weighing scale. The accuracy for the luggage weighing scale is probably something like +/-10 grams, while the digital weighing scale seems to haev an accuracy of  +/-1 grams. Nevertheless, it can serve as a great reference when you need to compare component weights. One advantage of using a luggage scale is that it can weigh large components such as a bicycle frame or wheelset, and has a much higher weight limit than small digital scales.

Am I a weight weenie? I am probably a "weenie" weight weenie, which means that I do care about losing weight off the bike, but not to the extent that I put in lots of money to obtain the lightest components. For me, changing a component to get a weight loss of less than 100 grams is probably not worth the extra money.

After looking at the component weights below, you will know if you are a weight weenie. If you find yourself checking out where to get a lighter component, you probably are!

Let me use the component list as seen in the Bike Comparision Series, "Cheap Bikes vs Premium Bikes".

Have you identified your next upgrade? Surprised at how much your current component weighs? You may be a weight weenie after all!


  1. awesome entry as usual! BTW, Matt uses the same wheelsport rim/hub and had a failure on the freewheel.

  2. The wheelset that Matt is using on his MuSL is Powerway. don't think there is anything wrong with the design, probably just high mileage, high power cycling and zero maintenance that caused the freehub failure.

    In any case, I did clean out the regrease my wheelsport wheelset when I first got it, and in light of what happened to Matt's rear hub, I shall overhaul the freehub every 6 months.

  3. Steve, can you tell me where did you get that weatherbeater like mudguards?

  4. Hi Steve, I am planning to upgrade my 20" wheelset of my stepdragon spa3 minivelo to a better one with faster rolling hubs. Any suggestions? Where do you buy the kinetic comp wheels?


  5. note that stepdragon minivelos may need 100mm width front hubs (which is the standard) instead of the narrower 74mm front hubs mainly used by Dahon. the kinetix comp wheels have 74mm front hubs.

    you can check out MyBikeShop, they do have standard 100mm/130mm 20" wheelsets, of Tyrell and other brands.

    1. What's the price range like?

    2. for Tyrell wheels, you will be looking at $400 at above

  6. Hi, i picked up cycling 4-5mths ago and i've been riding a tern x10 for the last 2 months. Could u help me with 2 qns?
    1) Do u have or plan to do a similar weight breakdown for tern X10's parts? I couldn't find information anywhere and I don't have the proficiency to dismantle my bike
    2) Is there a way to build a 7.5kg+ foldable (exclude pedals, grip and saddle since i wun compromise on those) for under 3k (or upgrade 1k from the x10).
    any advice would be appreciated as I don't know where to start.

    1. I can do a weight breakdown for the Verge X10... If someone gives me an X10 to take apart. Some parts such as the Kinetix Pro wheels already have their weight listed in this post.

      As for a Tern folding bike weighing below 8kg, it is possible, but it will cost more than 3k. Even the stock X10 with some lightweight components is already 9kg, and cost close to 3k. You may be able to further cut weight by changing the crankset and some parts to carbon, but it will not be cheap.

    2. Hi, sorry for the late reply. i lost track of where i posted this in ur blog (only bookmarked ur main blog).

      taking apart an X10: I have an X10. I'm tempted to let u take apart as u seemed equiped to be able to put it back. let me consider first!

      yeah, i have dreaming of a ultra lightweight and compact sub 8kg foldy for some time. i actually prefer those P9 handlebar that can swivel for folding for more compactness.
      i have been thinking of starting with a cheaper bike frame and upgrading the parts myself. but i'm not sure which frame to start with and what parts to put in... hence i'm asking here.

    3. I'm actually working on a new bike project that attempts to build an affordable, high performance, lightweight bike. Target weight is less than 9.5kg and cost of less than 2k. Should be completed in maybe a few weeks time so do check back once in a while.

    4. Hi, which frame are u starting with?

      Regarding "I can do a weight breakdown for the Verge X10... If someone gives me an X10 to take apart." Are you keen to do that? I'm interested to know and you can use mine.

    5. haha the keyword is "give".

  7. Hi Steve,

    I am contemplating between getting a Verge X10 vs the latest Tern P20, and then upgrade the wheelset to Wheelsports Super 451. My requirements is to be able to "try" to keep up with some of my friends who are on road bikes if we go cycle together. Which one should be better choice? Thanks.

    1. No matter how you upgrade a folding bike, it will never be as fast as a road bike, given the same rider on both bikes.

      My choice would be to get a Tern P20, and upgrade it to have exactly the components that you want. You can put all the top end components to save weight and improve performance, and it may still be cheaper than the X20.

  8. the other option is to just go with Eclipse X20 and do not have to worry about upgrades ?

    1. The Eclipse X20 is a different type of bike, with 24 inch wheels instead of 20 inch wheels. That puts it in a separate category, so can't compare with it.

      However, the bigger wheel size does bring it closer to a full sized road bike, so it will probably be able to achieve a higher speed compared to a 20 inch bike, given the same rider on both bikes.

    2. u mean verge X20?
      well, it's possible, but i believe the X20 is actually 9.3kg, only 0.4kg lighter for more than 1k more. I could easily shave that 0.4kg via seatpost and handlebar changes.

      I'm not sure how much weight could be shaved with a crankset/BB replacement as I'm not familiar with those parts.

  9. Hi Steve, I have a junction 1808 bike(8spd), I think its made by tern. I would like your advice, should I change the wheelset (saw a pair of used kinetix comp going for $120) or just change the hubs to novatec? current wheels doesn't freewheel much after I stopped pedalling. kinda tiring. or just splurge some money and get a litepro or wheelsport wheelset? thank you.

    1. Just get a wheelsport wheelset. Else after you get the kinetix comp you will still think about the wheelsport.

  10. Hi Steve, between a Wheelsport Super 451 vs Machete V Syuc 451, which is better? How do we test smoothness before we buy? Machete claims to be smoother than Wheelsport but it's heavy at 1.54kg. My current Dahon Pro 406 wheels is only about 1kg if I'm not wrong. Is the weight penalty worth it for the increase in wheel size for top speed?

    1. The only way to test smoothness is to spin the wheels, but even this does not indicate how well it performs under load during actual cycling conditions.

      The Dahon Kinetix pro wheels are very smooth, you can't get the wheels spinning smoother than that. The Machete has a high profile which might be advantageous at speeds above 30km/h, but will suffer in acceleration due to the weight.
      Weight increase at the wheels are very bad for cycling efficiency. You are much better off sticking to the Kinetix Pro for lightweight, or Wheelsport if you are going for the 451 trend. The Machete is good mainly to see.

  11. Thanks Steve. Am I correct to say that for the 451 wheels,the heavier weight on rotating mass is bad for cycling efficiency, so end up I may not get a higher speed as compared to my current smooth and lightweight 406 wheels?

    1. A heavier wheel will suffer during acceleration,but may be able to maintain the rolling momentum better once up to speed. My opinion is that there would not be much speed difference no matter which wheelset you choose between these two.

  12. Wheelsport Super451 vs Smart451 which would be a better choice to use for speed. For weight 95kg would this two wheels hold up.

    1. I am not sure what is the difference between those 2 wheelsets, you can ask for more info at the bike shop. There should not be a problem with the weight limit as wheelsport wheels are pretty durable.

  13. I wish the list could include all dahon stock parts so to figure out where it is the most significant change. For example, what is the weight of dahon's stock pedals?

    1. I don't really have any stock Dahon parts left so I can't give you an answer. However most cheap pedals with would weigh more than 400 grams.

  14. Hi Steve,
    I understand you ordered some of the stuff from Tao Bao. I'm looking at buying Litepro components for Tern Link D16 and Link P9. How to identify which is original or fake?

    1. If you get them from Litepro.taobao.com, they should be original.

  15. Hi Steve, I found your page very useful and I would like to contribute the weight of some stock items.

    Dahon stock Suntour pedals 599g
    Dahon Landing Gear with 2 bolts and washers 199g.

    For me changing out the subpar pedals and removing the landing gears saved almost 500g

    If you can publish these, that will help other bikers out there

    Let me know if you want me to send you the photos of those items on a weighing scale


  16. Hi Steve

    I have just bought a 2005 Dahon Helios P8 and am trying to bring down the already low weight (11.8kg with rear rack etc) while upgrading to a 1 x 10 speed as I need a 36 low gear for lightweight touring (Zee RD with Saint shifter). I know the SL version of the Helios weighs in the real world (with pedals etc) at just under 9kg so I am hoping to get to under 10kg. I expect the key components to change are the wheels, crankset and front fork (steel to al or carbon). WHat would you suggest?



    1. Main areas to save weight would be the wheels, tires, crankset, seatpost and handlepost.

  17. Hi Steve,

    Is the Tern 20" Xaris Fork compatible with Dahon Vitesse D7 frame.

    thank you.
