Need Advice on New Cassette

[D-Mike]

Hi Everyone.

 

I need some advice on the purchase of a new roadbike cassette.

 

I am a big guy, weigh in at about 94kg. I find that on the longer hills I really struggle i.e. going up Vissershok in the 99er I went at about 6-8km/h. Going up at that steep gradient was a real slog and it would have been helpful to have that one extra gear to shift down.

 

Anyway, I need to replace my cassette soon. I am currently riding with an 11-25 cassette and could go to a 11-28 cassette or a 12-27 cassette. What would you recommend?

 

Thanks

Are you using a standard or compact crank. If you are using a standard then a 12-27 cassette will serve you well, but if its a compact crank then stick with the 11-25 and ride more. 

 

I use a standard crank with an 11-25 ratio, and am 191cm tall and weigh 84kg. I also climb Suikerbossie at least 3 times a week.

If you riding 9 speed then 12-27.  You rarely use the 11 cog and the jump isn't too high in between gears.  Whereas the 11-28 has major jumps (up to 4 teeth).  

 

I ride a compact crank and a 12-28 (custom made).  I used to ride a 12-27 and loved it.  Best cassette in my books.

I am riding a standard crank with a 10 speed.

 

The 12-27 speed seemed to be the right answer. As Maniax said, the 11 cog is used seldom and I was concerned about the jumps in the 11-28 cassette.

 

Thanks!

Go with the 11-28, you will barely notice the missing gear from the 11-25

I have a 12-27 cassette on my training wheels which I would recommend.
