RyanV Posted February 16, 2016 Posted February 16, 2016 some advice would be appreciated. I have a question regarding climbing vs the gear ratios you have on your bike. I currently have 40/28 chainrings up front (11/36 rear). I got this as I thought it would make rocket away from my mates with their little 38/24 chainrings. Now when it comes to straights it's neither here nor there, so i don't really see a difference, but when it comes to climbs I get dropped like a rock. I'm pretty sure that my 28 ring on my 36 at the back is just too difficult to compete with any of my mates (even the guys with 3 x 10). I see guys that are much newer to the sport than I am coming past me on climbs on their 24t rings probably in their 3rd biggest/easiest blade in the back. I have however ridden a mates bike with a 38/24 and I could really feel that the strength in my legs seriously increased and I am thinking/hoping this could be because of the bigger chainrings I have gotten used to on my bike. So my question is this - Do smaller chainrings in the front allow you to select harder gears (smaller rings) in the back and that in turn adds more speed with less effort? I'm thinking of going Kalbo 1 x 32f-oval/42r, but then I think to myself would a 24 chainring not help me get up the hill faster if it will allow me to select a harder gear in the back as apposed to having a 32 single infront? I really would like to try the Kalbo oval setup. Hope this all makes sense....ek moes kop hou ;-) The other explanation could also be that I am just plainkak and should HTFU! I thank u.I'd have to ask whether you and your buddy are riding a 26er or 29er. 40/28 is a good setup for a 26er, but you need to look at a lower gear ratio for a 29er (38 or 36/24 is standard). It's not just the size of the gears you are pushing, but also the size of the wheel! A 29er also gives better stability and traction when climbing.
EmptyB Posted February 16, 2016 Posted February 16, 2016 Loads of research and pseudoscience surrounding this topic.Trial and error to find what works for you..I was running a 34T front elliptical chainring and an 11-40T Praxis cassette (10 spd) and I could climb just about anything around here. The steep conc on Noordhoek Peak and Mo*#@F*R on TM were just about at the limit of being comfortable. I tried a 32T front and have decided to stick with that now, I lost a little bit on the flats initially, but my leg speed has improved so I've got that back. Also my legs are not fried anymore from grinding the climbs. Having said that, there's no better feeling than turning a big blade and just feeling the power flow at speed. Big blades, if you can turn them, also have less friction...Ja but there's a motor in that bike...
'Kaze Pete Posted February 16, 2016 Posted February 16, 2016 I have an offensive, not-so-humble opinion in my approach to gearing (which may just be my naive ego talking). It doesn't matter what ratios you run. Pedal your damn bike and break dreams! At least that's how I see the single speed riders understand it. FRIB!
DoubleJ Posted February 16, 2016 Author Posted February 16, 2016 Why are you selling the bike now?Just kidding

I thank u.If your gears are too hard you will spin slower and get tired quicker. Cycling more will improve your fitness and pushing bigger gears will make your legs stronger in the long run....but you might have more fun with easier gears. 40/28 is quite long gearing for a 29er. 38/26 or 38/24 is a bit more friendly for the average cyclist on a 2x10 29er. Also make sure you actually do have a 11-36 cassettes. 11-34 and 11-32 are also available in 2x10 and are sometimes fitted to new bikes.
Deon M Posted February 17, 2016 Posted February 17, 2016 Remember too not all of us are the same. I prefer higher cadence and my riding partner lower. I normally ride a 1X11 32-42 and he rides a 1X10 34-40 and we climb about the same speed. Also depends on gradients you ride on the Tankwa Trek I changed to a 30-40 and had no problems on the Marino Monster. My advice is ride a few different setups and see what works for you.
