Cassette on new bikes.

[Ajax Bay]

Lots of chat about the merits of the largest sprocket having x teeth but none about the relative waste of a sprocket by having a smallest 11t when 12t will do for mortals.
Have a play with this:

I like my 11T

Despite regular claims on this forum that an 11T sprocket is a waste I find it a useful and often used gear.

Yes i would not be without the eleven tooth. Most people in our club run 11-28 or 11-30.

I've gone to the Spa Cycles website shortly after buying both my road bikes. They have a fantastic selection of chainrings.

I also shop around for different cassettes , and mainly ignore the "Tooth Rules" about combinations that are "allowed". I'm still absolute rubbish on hills but, on a good day, I might get to the top without stopping. It's not a pretty sight, but I really hate walking.

Me too. I use it far more than the 12T next door
Basically, down a decent hill, if I want to keep pedalling, it's 52/11

Have i got this right?

Well, I changed to 52 x 13 for the downhill, but I spun that out well before hitting Vmax.

I can get to 35 mph in my 48/12 top gear. Any faster than that, I just stop pedalling, tuck my elbows in, and get my chin as close as possible to the handlebar stem. I can get to 55 mph freewheeling down some of the local descents and I don't really want to go much faster than that on a bicycle!

Max speed of 45.6mph today coming down The Tumble with 50/11 on a windy day!

I could have pedalled a bit more but decided it was more sensible to stop trying and concentrate on staying on the road....

Not bothered how small the small cog is.

My downhill technique embraces a very low calorie method of rewarding myself for toiling up the uphill.

In other words: "Wheeeeeeeeeeeeeeeeeeeeeeeeeeeee!!!"



Yes, I have been known to employ that method myself.

As far as I am concerned, there is no other! Pedalling downhill? Weird...

Pah, 60 mph on my 1989 steel bike (OK the Posh one) - many years ago. You are better off not pedalling and going aero and relaxing after about 40.

I could do 40 every ride locally down 'Otterspool' - far more efficient tucking in.

PS old and broken now....
