Hello Guys,
I have set up a time trial bike single gear its very fast 50t chainring and 14t rear. However, the new ironman race route in my location requires crossing a bridge with obviously inclined slope. I'm used to going uphill but it burns significant amount of energy. Btw, the new route has 3 loops which makes it a little disadvantage on my part going up and down the bridge 6 times. Having experienced this, I was thinking maybe putting a double chainring like 52t & 36t with front shifters would decrease the tension for the climb? Do you think this is possible? I'd appreciate your input.
Thanks!
Max
There's one path to do fixed gear change:

Any other option is overly complex, unreliable, possibly
unsafe or (as with a two-sided wheel) ungainly.
If that's what you need, the SA S3X, or vintage ASC, suits
perfectly.
