29-sized wheels are the larger sized wheels in mountain biking, so if you are climbing with these wheels, then you will tire much and it would be hard to pedal your bike due to their larger size, but when you pedal these will cover a greater distance than 27.7 and 26 wheels, so it means if you are a tall rider then 29 sized wheels are better but if your age is old, with less power and energy and with shorter height, then 29 sized wheel are not good for you in climbing steep uphills, because these wheels cost a lot of energy and finally eve it would be hard to pedal and you have to walk with your bike on steep climbing trails.
29-sized wheels also depend on the bike geometry, weight, and the material of the wheels, if your bike is modern and expensive with less weight then 29-sized wheels are the best option, but if your bike does not have front and rear suspension and your bike geometry is not giving any support in climbing uphills and also the weight of your bike is heavier to climb uphills then 29 sized wheels would also affect negative response on the rider, because of the bike geometry, buy lightweight 29 sized compatible wheel bike for climbing uphills and downhills.
Aluminum bike frames are harder to climb with the 29 wheels but if your bike frame is of carbon fiber then 29 wheels are the best and recommended option for steep climbing.
You also have to look for the climbing trails where you are going to climb with 29 wheels, if the trails are too steep, then 29-sized wheels are not a better option, but if the trails are not steep and you believe that you can easily climb with the 29 wheels then it is better, mostly on twisted and rough trails it is hard to climb with the 29 sized wheels because the trails contain corners and twistings and you have to turn your handlebar on every corner, which is difficult for the rider.
Timing Of The Climbing Uphills With 29 Wheels:
Uphill trails are different for different countries, towns, and parks with different mileage distances, if uphill trails are short and you climb easily in less time, then 29 wheels are a better choice, but if the trails are longer and you take almost more than 2 to 3 hours in climbing then 29 wheels are not a better option for selecting for longer uphill terrains. smaller sized wheels(27.5 and 26) are recommended for long-distance uphill climbings and 29-sized wheels are not used for greater distances.
Riders’ Stamina And Foot Pain:
there are many riders who suffer from asthma, tuberculosis, and other lungs diseases, it is also common that riders are suffered from foot pain after riding for longer distances with their bikes, for these riders 29 wheels would not a better solution for climbing uphills because these diseases and pain would increase when you pedal your bike with a force and energy on uphill trails, and 27.5 and 26 wheels would be better for them.
Weight Of The Rim:
If wheelsets of 29 wheels are of aluminum metal and steel, then these materials are heavier than carbon rims, and also double-walled rims are much higher than the single wall rims, many riders would remove the inner layer of the double wall rims on their 29 wheelsets to decrease the weight of their wheelsets for climbing uphills.
Tread And Combo Pattern Of 29 Wheel Tires For Climbing Uphills:
The tire tread pattern is also important for uphill bikes, because if the tread pattern is causing much more friction and rolling resistance with the uphill trails, then 29-sized wheels would not roll better and your bike speed will decrease resulting in spending a lot of riders energy on striking of pedals, hidden and smaller tread pattern tires are used which have relatable pattern same as that of slick mountain bike tires, you can easily climb with less combo and less tread pattern of tires with larger wheels.
Thickness and width of the tires would also matter on 29 wheels, greater width tires are better in climbing uphills than narrower tires, so always choose thick tires for climbing uphills with 29 wheels.
Tire Pressure For 29 Wheels For Climbing Uphills:
You also have to check the recommended air pressure for both front and rear tires of 29 wheels, pressure for a rear tire is 28 and for the front tire is 23, lesser or greater air pressure within the tires would also affect your ride especially on climbing uphill trails, recommended tire pressure for climbing uphills decreases rolling resistance of the tires and also decreases the value of the center of gravity and friction with the rough trails.
Difference In Men And Women With 29 Wheels For Climbing Uphills:
It is common and has been proved by experiments that women would never get tired easily with larger-sized 29 wheels on climbing uphills but men would easily get tired after a few pedal strikings, I also don’t know the logic behind this term, but I have also seen many women, these are peacefully pedaling with the greater sized wheels on uphill trails.
How To Climb Better With 29 Wheels:
In racings, when the riders are climbing uphills, almost all bikes are 29 sized, because these rides select larger wheels, the reason is that larger wheels would give better traction and control on uphills, but if the weight of your 29-wheel bike is heavier then never ride uphills, the weight of the bike would also matter a lot in climbing uphills.
Advantage Of 29 Wheels For Climbing Uphills:
Larger wheels would spin freely and do not stuck anywhere on the trails, when you are pedaling 29 wheels is also rolling and do not dig within the sand and also do not slip and skid above the rocks and roots, but smaller wheels work oppositely to larger 29 wheels, it is the reason that most riders prefer larger wheels for climbing purpose than smaller wheels.
Bottom Bracket Height:
It is also the main part of bike geometry which is responsible for increasing and decreasing bike speed on climbing uphills, larger 29 wheels have raised bottom brackets and smaller wheels have a lower bottom bracket, so you have to check the height of the BB on your bike frame and adjust it accurately so that it should be compatible with the larger wheelsets for steep climbs.
Length Of Crank Legs:
Crank legs would also matter for sizing with the greater wheels, you have to choose the compatible sized crank legs and wheel size because different-sized crank legs are not compatible with the smaller or larger wheelsets and the Q factor is affected much which will affect your ride on climbing trails.
