I am a beginner to commuting by bike and I find it very tiring. Is it my fitness level or my single-speed bicycle?

Was going to comment, but I'll make this an answer - it's the bike, not you. No, I really do mean it's the bike..... The bike as a fixie with 48/19 gearing is suitable for a cycle fit 20-something ...

Why don't seat tube lengths on modern bikes match their assigned sizes?

ANSWER The "frame size" is no longer a physical measurement on the bike. Instead its a "virtual" distance. Remember traditional horizontal top tube frames? These have been "...

Is it possible to measure your sit bones at home?

Making bigger steel frame smaller

It isn’t possible to resize a bike like this. You would be talking about removing each individual tube, cutting it down to size, and then rejoining them. We would be talking about all the tubes, not ...

I am trying to find a trailer for a disabled adult

There are a lot of options that don't involve a passive trailer. Moving two people with the energy of one person means that hills are to be avoided. You'd struggle to get up an overbridge or short ...

Should saddle height be changed in relation to different crank arm lengths?

Actually, imagine your leg at full extension. With longer cranks, your foot is 5mm further away. To maintain the same leg extension at the bottom of the stroke, you would lower the saddle with longer ...

How to be certain a Boardman ADV 8.8 would fit without prior road bike experience?

Why do people seem to choose "aero hoods" over "aero drops"?

Short version: If you raise the bars, now the drops are too high for their best use: steep and technical descents. Longer version: “Aerohoods” are used in flats. You can get the brakes if you need to, ...

Is Lemond's saddle height method outdated?

(The Lemond method is to measure inseam by 0.883 in socked feet and use that to set the distance between the BB center and the top of the saddle). The Lemond method gets into the ballpark of correct ...

Unable to get into a 'TT' position, is my bike fit wrong, or am I just fat?

A bike fit is not intended to make any position you can adopt on your bike work. If the bike fitter did their job correctly, then would have set you up for your current level of flexibility, ...

Adding gears to my grandson's 12" bike

If your grandson is that young, he's likely to have trouble keeping up with you no matter what bike he's riding. It may be that it's your expectations, not his bike, that should be modified. It seems ...

I'm an absolute beginner in bike touring, about to buy a bike. Is it worth it to hire a bike fitting service before the purchase?

Welcome to the cycling world. This is a good question. It may not be possible to answer entirely objectively. My vote is not to get a professional fit now, but I'll outline some considerations that ...

Do smaller riders tend to need a wider saddle?

No - smaller riders tend to smaller saddles, all other things being equal (like gender). However females tend to have wider hips for biological reasons, so the sit bones are further apart on average ...

Does it really matter if my stem doesn’t block the hub?

4.1 miles, mostly flat, are on paper doable by any human with two legs in about 90 minutes. Walking. A bicycle? it should be at least 1/3 quicker (although I would expect it to be 3 or 4 times faster ...

Is a dropper post a good solution for sharing a bike between two riders?

Using a dropper for this purpose is not a good solution. Droppers do not let you easily choose a set height other than all the way up or down, and most of them don't give you a quick visual way of ...

How much can we change our bike wheel diameters before needing another bike fit?

The thing about bike fit is that it's almost exclusively about relating your body position to the mechanical parts of the bike. The relationship between handlebar, saddle and pedals is unaffected by ...

Almost all road bikes have your torso leaning forward to some degree, meaning you have to hold your head up constantly. If you've never ridden a true road bike before, you've probably never had to do ...

What are, if any, the signature postural differences between riding a 26″ bike and a 29″ bike?

Wheel size can sometimes have repercussions on fit due to the bike design considerations where wheel size is a factor. But, those considerations largely deal with design choices rather than absolutes. ...

What is the problem with adjusting brake levers to end their travel "too close" to the handlebars?

The issue with having brake levers which have travel that ends very close to the bars is that, as the brake pads wear down, the brake levers will hit the handlebars before the brakes are fully engaged....

Pedal foot position - balls or arches

The ball of the foot gives a large, strong, stable area to use on the pedal, and gives you a nice lever to use your muscles effectively. Conversely, the arch of your foot is soft, elastic and not ...
