I'm looking at increasing the size of the chainring from a 48 to a 53. The question is, is this a straight forward up grade or does this open a can of worms?

48 x 11 on a 26" is 113" top.
Now I'm even more confused.....
I'll tell you how many times my SWorks 17 lb race bike has been in 53 x 12..... can't remember.
Oh yes, now I remember. It was through Birmingham's Queensway tunnel at 40 mph with the airflow of the traffic pulling me along.
Yeh, maybe you need a 53 x 11 on a 26" Hybrid.
I do find myself in top gear on a regular basis and from time to time find myself looking to change up. I'm looking to replace the triple from current set up 26 36 48 I belive to 30 39 50. I have taken onboard the previous threads hence the change in direction to the triple with a 50.
Or the help of a big bunch of riders and/or a very favourable tailwind! I was lucky enough once to ride down a valley on the Costa Blanca with about 30 other riders and a 15 mph tailwind. We were doing 35 mph no problem at all!RedBike said:Most people recommend you pedal at about 80/90rpm so a speed of 30/35mph in top gear should be sustainable. You aint going to be achieving this sort of speed without the aid of a good hill.
getfit said:It's fair to say that my fitness/ability will not allow me to get any decent constant speeds as my other threads will verify however I do live in a hilly area and often find myself running out off gear on sustained downhill sections. This is where I feel the 50 will come in handy.
