What length top tube should I get?
So what does this all mean?
| How tall are you? | Bike size | |
|---|---|---|
| Centemetres | Feet and inches | Effective top tube length |
| 148 to 152cm | 4ft 10in to 5ft 2in | 47 to 48cm |
| 152 to 160cm | 5ft 0in to 5ft 3in | 49 to 50cm |
| 160 to168 | 5ft 3in to 5ft 6in | 51 to 53cm |
Is top tube length or reach more important?
Reach is more constant. Consider a rider who is 6′ tall with two bikes; both bikes have a listed ETT of 610mm, but they have different seat angles. ETT is always measured in a parallel line to the ground starting at the top of the head tube.
Is a 56cm bike medium or large?
This is your most important consideration. Frame size is related to the seat tube length. For example, a 56cm frame will have a seat tube that is 56cm long….Road bike size chart.
| Height (inches) | Height (cm) | Frame Size (cm) |
|---|---|---|
| 5’9″ – 5’11” | 175 – 180 | 56 – 58 (Medium – Large) |
| 5’11” – 6’2″ | 180 – 188 | 58 – 60 (Large) |
How important is top tube length?
While effective top tube length provides a good idea of the overall length of the frame, it will be influenced by the angle of the seat tube, increasing as the angle gets slacker.
How does top tube length affect handling?
While the seat tube length doesn’t directly affect the handling of the bike, important measurements for handling and fit, such as reach, must be compared to the seat tube length to define how long the bike is relative to the height of the rider.
Does seat tube height matter?
Why does it matter? Historically, Seat Tube Length was used to determine the Labeled Size of a bike. These days, seat tube length is still important in some cases: To understand the lowest position of a saddle, especially important when sizing up to a larger frame or considering a bike with a classic, level top tube.
Is longer reach better?
A longer reach can be very helpful to have room to move around. Also, it helps if you prefer running a shorter stem and having a quicker turning front end. A longer wheelbase keeps the bike in control on high-speed sections. The bike becomes less twitchy and can help smooth out some rough sections.
How do I know if my kid bike is too small?
If you think your child is outgrowing their bike, take a look at their feet and angle of their knee. The experts at Schwinn and Mongoose told me a child should be able to touch the ground with the toes of one foot while sitting on the seat, without having to lean the bike to that side.
Do pro riders use smaller frames?
In more modern times, pros often use a smaller frame that a similarly sized recreational rider because they want to ride a big drop to the handlebars. As head tubes continue to grow for a given frame size, pros are forced onto smaller frames to maintain their positions.
Which is longer the down tube or the top tube?
However, effective top tube length combined with seat angle tells you virtually the same thing as down tube length.
What’s the difference between effective and actual top tubes?
Two bikes with the same actual length top tubes could have completely different effective lengths because of the angles, making one in reality much smaller than the other. If your trying to compare your 456 frame to one your buying, your better off measuring the effective length of the 456 as reference.
What do I need to know about the top tube?
This includes the effective top tube length, the length of the head tube, the length of the seat tube, and the angle of the seat tube. The height of the bottom bracket can also be important, but not strictly necessary if the stack and reach are provided, while standover height and the front-centre measurement can be considered secondary measures.
How are top tubes different on different bikes?
Thats the important measurment when comparing frames, and the actuall length dosent matter. Two bikes with the same actual length top tubes could have completely different effective lengths because of the angles, making one in reality much smaller than the other.
