Fun triple GEARING setup

I just built up another MTB converted to drop bars.

I put on a 28-38-48 triple crankset. For fun I rooted through all my spare cassettes and took out the pins to separate the cogs. Then I sorted the cogs and built myself a 9-speed straight block 11-19 cassette. Tires are 2È x 2.0 knobby ones.

The high gear is 108 gear inches and the low gear is 39.8 gear inches.

Took it out for a few rides on rolling terrian with varied road surfaces ranging from smooth as glass pavemet to very bumpy dirt roads.

It seems like I was able to get the EXACT gear I wanted even when there were only slight variations in the inclines or road surface changes.

I just might leave this as it is.

Cheers

Kin yah no read Laddie? That 28 - 19 gear is 39.8 gear inches and a 42 - 28 gear is 40.5 gear inches. Either is plenty low enough for a LOT OF HILLS.

Cheers

That is roughly what I use on my "Phuket Bike". I probably have never
used the 108" combination but I can tell you that I certainly use the
lowest gear. Usually coming home from a 4 hour ride and climbing the
big hill I need to get over to reach the house :-)

39.8 as the low gear on a triple. Must nut be very steep hills. You'd be
doing a lot of walking around here. An 11-19 seems especially strange
with only a one tooth difference per gear.

This is what you'd use here, a 12-36:

Or do a 3 x 11 with this 11-42:

I've been using a 13-23 9speed with 30/42/52 triple for years now. Due
to slackness in maintenance the 23 has been inaccessible for most of
those, so effectively 13-21 8 speed.

Low gear 30/21 = 38.5in.

It was quite hard getting it up the 20% hill near our house when there
was a massive headwind, but I made it. I must try it now I've got a new
chain on - last time the limiting factor was chain slip, not gear.

So no, it's not a drastically high bottom gear, and for a fit person, no
need to be walking steep hills.

The one-tooth difference per gear is nice to have.

He lives in Ontario. Why does he need a bike that can get up your hills?

Just had to chime in. I have been pretty happy with my double chainring, 9-speed setup: a 34 - 50 compact crankset with 26 - 12 cogs. It gives a 35-inch low and it's mostly a two-tooth-increment cassette. We have a lot of hills around here.

Once again SMS shows he doesn't know what he's talking about.

My 28 - 19 low gear of 39.8 gear inches isn't that much higher than the 37..6 gear inches of a 39 - 28 double.

I can climb some prety steep hills with my 39.8 low gear. Besides, like yiou said, my gearing is for me in the area I ride in not for someone living in the mountains.
