@stinkybeam3 years ago You forget mention chainring offset. If you go 1x on you road bike, you' d better make sure chainring has 2 or 3mm offset. Or you might have some noisy " cross chaining" problem. 8

@mikelohmeyer41403 years ago I am planning to do this soon and going with an oval front ring on my road bike. Not looking for any massive gains just looking to make some cousin medic changes. Will the oval front ring hurt me in any way?

@galenkehler3 years ago Using a track crank will correct the chainline to the center of the cassette. Less grinding up the hill.

@mariocbernardo3 years ago hi alex n ollie. What size is that single chainring, 56t? It will improve the topspeed isn't it?

@zedtony81103 years ago What about a 10-50 cassette so the bike is not just good for the flats. 4
@

@nick377813 years ago Make sure your bike has a chain stay long enough for 1x drive trains so that you dont have chain crossing emulating. 2
@

@marksharma-drake10163 years ago A few questions:
1. A single chainring ideally needs a different chain line. The video didn' t seem to address this. Is it as simple as removing 2. I run force axs 2x. The system is designed to not allow first gear in the big ring, so if i remove the front derailleur then the system won' t go into lowest gear. Is this correct?. ...Expand

@sepiarain3 years ago For anyone doing this, absolute black have a perfect chainring for the job! Narrow wide teeth and oval. I was riding 1x10 for a year before my accident - favourite setup. 2

@steamtrac3 years ago The most important topic - axial position of the sprocket (or the chainline) was not captured. Thats really unfortunate. 9
@

@whatwelearned3 years ago When (if) we can get 15 gears on a single cassette then i' ll switch. Before that it' s just not worth losing that range. 3
@

@unairamos743 years ago Jon's video from 3 years ago inspired me [ ] and since them there's no way back for me. 1x is the way as it simplyfies the whole system and makes your bike more fun to ride. Most people don't know that in a typical 2x setup some gears are not usable (like biggie-big and small-small), plus some other gear combinations that are duplicated throughout the gears. That leaves a typical 2x11 set with some 14-15 real different gear ratios to use, not far from a 1x13 setup anyways. .. ...Expand 2

@alainbellemare21683 years ago You will need to change the bottom bracket axel otherwise the cross over chain effect can be brutal, you want to bring the front gear closer to the frame, . ...Expand

@super8hell3 years ago 1x is so easy and almost mindless in terms of picking the ratio. I have 52 in the front and 11 speed 11-42 rear cassette, which easily covers the range . ...Expand 1

@celpabedn6 months ago How much top speed do you lose going from 2x to 1x?
@

@DamnitsAdriel3 years ago 1x is good when you have a longer drivetrain. But if you have short distances. That chain will bend more, and decrease your efficiency.

@Omegaparsec3 years ago Dudes with campy wheels: " i' m going 1x cuz front derailleur is too noisy"

@

@danthxman3 years ago Just be aware to anyone converting to 1x with a modern road bike that due to shorter chain stays that a single chain ring can be quite noisy in the extremes of the cassette. Tt bikes are usually much better.
@

@philspencelayh54643 years ago When i bought my bike it had a 2 x set up and replaced the chainring with a triple, huge improvement a gear for every occasion! 4
@

@teresanietoaraujo27709 months ago This bike was really easy to assemble and required very few adjustments out of the box. The wheels did not require any truing/adjustments. The frame had some small scratches, but nothing major.I did replace the seat though - the seat it came with was very uncomfortable. The tires need to be re-inflated every 4-5 days, but this appears to be quite common for the narrow 700x25 tires.Overall, in my opinion, this bike looks and rides like a much more expensive bike. .. ...Expand
@

@tibiolah3 years ago 1x setups have been around for ages before the front derailleur was invented.
@

@joules5313 years ago Crikey! With such a tight rear triangle that' s going to cause some seriousgood tip to just cover the front di2 cable, rather than removing it, cos plenty of peeps are gonna switch back to 2x, once they find out how noisy that tightly cross-chained chain is. ...Expand 6

@johnnybravo19123 years ago Stick a sram gx axs upgrade kit on your road bike.
@

@bikepackingadventure79133 years ago If all your doing is removing the inner ring and changing the outer ring, wont be chainline be wrong?
a 1x chainset is designed to be able to r a double chainset is as far as im aware not designed to run smoothly throughout the rear cassette due to chainline.
also if you turn a double chainset into 1x then you will most likely needto change the bearing on your rear cassette.
i dont think its that easy to just change your outer ring on a double chainset and still have a smooth running gear system and a wide range of gears.
thoughts. ...Expand

@alainbellemare21683 years ago If you remove the bottom bracket, gears, pignons, derailleurs, chain, you will save all kind of watts, be more aerodynamic, save weight, but you will use your shoes faster, even more if you remove the brakes.
