How to get faster
Hi all,
I currently ride 38kms one way to work, with 300m of climbing, using Cannondale topstone apex 1, all stock but: schwalbe marathon supreme tyres to have a good balance between durability and speed. I did have 3 flats on the 120 rides I did to work. I do have to cross brussels, so having something puncture proof is a must. I also use pannier to take my laptop, breakfast, clothes and lunch with me. The laptop is certainly not daily. I do have sks longboard fenders I do this commute 2 to 3 times a week, but it is not always a chill ride. it takes me around 1h20 to 1h35, depending on the wind. now, how can I become faster except cycling more? Things I thought about (in order of what I think will be more effective): - bike fit: would this help me be less fatigued and maybe in some way thus faster? - gp4000/gp5000 tyres,though I'm afraid I'll have a lot more punctures. Brussels is not Amsterdam and not so bike friendly. - backpack instead of panniers to be more 'aero' and lose some weight. Even though I don't have a good backpack and I'm afraid of backpain as well. - ditch the dropper post & get other wheels. If the above would not have much effect I'd just have to pedal more I guess. Thank you all for your input! Many happy kms! poeli |
That's a respectable commute distance, and a very respectable time at about 25 km/hr.
Honestly, it's going to be tough to better that performance level. The only thing I can think of that might help is if you can change your route a bit (but not much!) to avoid stop signs and/or traffic lights; but I don't know if you're riding on grade-separated bike paths already. It might be worth trying some of your ideas (bike fit, tires), but I wouldn't expect too much difference in timing; perhaps 5 minutes off each leg? You could try the backpack; I'd start with a cheap, perhaps a used backpack from a thrift store or similar. Only you can tell if the additional speed that's possible is worth the sticky, sweaty back that might bring. Oh, one other idea; is there a bus or train you might catch to cut 20 km or so off your ride? Something with a bike rack, naturally. |
Much respect for riding that far on your commute. I always appreciate folks who are open-minded about learning new things. I think as a daily commuter I am constantly trying to figure out how to be more efficient, whether it's getting marginal gains in speed, dealing with the weather, carrying cargo, lighting and other electronics.
If you're bike is a poor fit, that's the first thing I'd address. Having a good-fitting bike will go a long way in making your ride more enjoyable and pain free. Tires are always a compromise. So, you pick which is more important to you. I've run 25's, 28's, 32's, 35's and 38's on commutes, with more puncture protection on the wider ones, but I've had punctures equally on all of them. The difference in speed on my 40 km round trip is maybe 8 minutes. I am using 35's currently, find they are a good all round. I don't like the panniers. Ditching them will probably make the most difference in your speed because for me they act like a pair of parachutes. I have carried heavier loads on a backpack, and I find that the position I ride with a road bike, the weight of the bag sits on my back rather than hang off my shoulder. And I have carried a backpack on longer 100+ km rides without any issues. Hope that helps. |
My commute is much shorter than yours, but I notice that the only thing that makes any appreciable difference on time is whether the stoplights are in my favor. Doesn't matter if I ride my race bike or my old mountain bike.

Backpack might actually make you slower due to discomfort from the weight and cutting off cooling airflow to your back. Panniers don't really add much to drag because it's already sheltered from the wind by your legs.
That was my experience between using backpacks and pannier. I recommend you keep using panniers for your cargo. What can make a huge difference in aero is your riding posture and the type of clothing and helmet your wear. |
Here's a comprehensive study on how aerodynamics affects bikes:
https://www.sciencedirect.com/scienc...67610521001574 It's not my experience that panniers don't add drag. They add significant drag to a moving vehicle. |
First off, congratulations on your commitment to commuting.
We've long known how to get faster: more power and less drag. You'll get more powerful with continued riding, so that's taken care of. Reducing drag depends on exactly what's slowing you down (traffic? hills? wind? roads?) and we don't have enough information about that, but in general drag reduction is about lots of small changes that add up rather than a single big change. Without changing your tires or position, you may be able to achieve small improvements by switching your route slightly to avoid traffic lights and small climbs, from panniers to a small backpack, and by wearing tighter fitting clothing. Loose floppy T-shirts or jackets and loose pant legs add quite a bit of drag. Each of these changes individually may not make much difference but together they can save you a few minutes even with no change in your overall power output. Best of luck. |
Thanks you all for the repies! I might study the route but I don't have much choice to cross brussels :)
Part of the fun is to optimize everything and improve. I'll try a small backpack instead of panniers ( or use my saddle bag whrn not taking my laptop). in the beginning, the 38km was killing me! It's al about having the discipline to keep doing it and it will improve |
If you can scout a route with less stopping and less climbing that is a good bet. It doesn’t just pause your time, it exhausts you.
Also good if everything on your bike is working properly. Drag from seals and grease is baked in, but drag from badly adjusted or filthy bearings can slow you down while it’s also chewing up your bike. Tires can make a difference but it’s a trade off. Faster lighter tires have less armor. Light tires are just nicer to ride on. That’s why some of us go tubeless, but it’s not a panacea either. Slick tread is faster. If you are going fast enough to worry about aerodynamic efficiency then it’s easy to understand. Get in the drops. Smooth round shapes, which means tight fitting clothes, nothing flapping, no luggage outside your front silhouette |
I have a similar commute and I have an E-bike on the way. Have you considered that?
|
Ebike is a great idea for that distance. You could conceivably do the commute everyday.

Same issues as riding a standard bike, yes? The E-bike can be pedaled vigorously if you are cold, and you would be in the cold for less time. Many E-bikes come with a super bright headlight.(1050 lumens on the one I bought). I bought a Juiced CrossCurrent X ( https://www.juicedbikes.com/products...12524643975191 ). I chose this one due it having an 80+ mile range, and seems better built than the competition for the price.

yes for sure! I will test one in a few week to see how it goes. In summer when there is a lot of Light and good weather (even rain doesnt bother me in summer), its all fun. But in winter it can be cold and very very dark

I had an aero bike ( systemsix ) and a topstone alloy shimmano 105 (2019/20 model I think? before they changed the name to apex 1 2 3 4 ) at the same time. I used to ride them both on the same 10 and 20 mile loops.
When I put the road wheels from the aero bike on my gravel bike the times did not change much at all in stop and go commute traffic. I have a 37 mile loop route that I optimized with less lights, going clockwise ( right on red etc..) on this route there's 1 to 2 mph difference in avg speed which is a lot. I have had bad luck with gp5000 and flats. I still use them when I want to go fast but I would not use them as my I have to get work tire. My day to day tire is tubeless gravelking slicks in 32mm. These I ride on gravel and road all time. I am not sure how that compares for speed to your schwalbe marathon supreme. Aero clothes and body position make a night and day difference when going over 15 mph / 24kph. kind of embarrassing :-) I used to wear just normal clothes while biking. BF helped me out. ha-ha What to wear @ 20+ mph? |

Thank you all for your input! Many happy kms! poeli My commute is 44 km long, and in the beginning it took me 2h30 (3h - 3h30 on my way back home) to reach my destination but after 4 years i finally got that time down to 1h45 (both ways). These are the things to keep in mind :

The GP5000 S TR is a nice choice for that, being lighter, fast and tubeless ready. It isn't as tough as the Marathon Supreme, but I don't think the Onestar TLE versions of the Marathon Supreme are available anymore, and they were heavier anyways. I used the 35c TLE Marathon Supremes but I'm down to my last 2 tires, so have been testing the GP5000 S TR in 32mm, and they are quite a bit faster. I'm saving my MSs stock for touring, and using the GP5kS for commuting. Now adding all this stuff will probably be in the hundreds of dollars, more if you get someone to install it for you. So you may want to consider just getting a fast commuter bike instead and run your topstone on gravel/off road. |
I have nothing to add to this thread other than I can attest to this remark:

Switching from a pannier to a backpack, will lower your Cda. However, depending on how heavy it is, the toll on your body, in terms of heat etc may make that aero gain moot. I know I don't like a backpack for a long ride, especially in summer heat and if it's a heavy bag. |

When I switched to 32mm GP5000 S TR (not the TL), the marginal gains were in the long straights and climbs (rolling resistance), and down hill corners (grip). In the city traffic, there is literally no gains. Equipment efficiency gains from tires/wheels will be at best very marginal, depending on your route. I gained about 10W on the flats. The biggest gains will be gearing optimized for your ride, which is why I asked about your drive train. No matter what, you won't be cutting off 20 minutes off your commute with just equipment change.

I know I won't cut my time by 20 minutes, but small improvements combined should give me some minutes (but no way double digits). thanks for your post! |
If most of your commute passes through urban centers with lots of intersections with medium to heavy traffic, there's about nothing you can do to get faster on commutes unless you're only holding a speed of around 12 mph.
If your situation is the opposite and most of your commute is uninterrupted open / country roads, then the best possible tech can certainly help but not by a large degree. In such situation, good quality training would give you the best performance boost if you already have a decent bike. But gear-wise, the best performance boost I got excluding training is simply wearing aero clothing! You don't even need the most expensive line and even a bottom tier reputable brand clothing would already give you immediate results. So I'd say, wearing aero clothing is probably the most cost-effective performance boost outside of training. It will also help you in climbing trust, in days with headwinds and for the simple fact, you'll be starting the climb with fresher legs because you didn't have to fight as hard in the flats. |

Indeed, training and in addition, fueling and hydration. The faster you ride, the more you need to eat and drink to aid recovery and get to your destination / work feeling fresh and energized as opposed to feeling worn down and fatigued - not a good thing if you have to work. |
