All through the winter, I have been riding my SS Giant Bowery with a 69" gear. I tend to stick to a regular circuit of about 24 miles over a lumpy North Downs route. It's not a fast course and typical times on my single speed are around 1:40:00 (avg 14.5 mph). In the summer this comes down to under 90mins.

So this weekend, the first day of spring, I decided to abandon my Giant and give it a go on my gears bike- my ribble. Thought I would smash my time this year for the course, used all the gears and gave it everything I could (for a young 64 yr old).

Got back and my time was 1:41:19 (avg 14.3 mph)!

Next time, back to my SS.

I know that feeling. I find on rides under 30 miles the time/av speed difference between ss and geared bike is minimal. I find with geared bike I can ride for much longer though.

it's more than two years since riding a geared bike and there's a bit of me thinking I'll be transformed to a cycling god when I next try it, with massive power uphill, smooth style on the flat and the ability to go forever. I will get that geared bike at some point but for now I'm happy to live with the fantasy, grit me teeth and mash on into the headwind.

I wouldnt beat yourself up about it Keith. How many guys of your age do you know who could keep up with you.

As you know every day above Ground is a good one and your doing your bit to keep it that way.

I invariably log faster times on the fixed gear than on any geared bike. The fixed gear is lighter, but I don't think that's what does it. On the geared bike, I set the gear (and, so my speed) by how hard I want to work. Slow down on the ascent, speed up on the descent, but put out the same effort all the time, more or less. But on the fixed gear, if I have to work harder to maintain a decent cadence, I work harder. If I don't get up the hill at a reasonable speed, I'll be walking. Result? I go faster. Quite a bit faster.
Here's my fixie last time I took it out:

My thoughts (above) as well.

Have had an off/on relationship with fixed all my life. My first was a Hill Special, my 10th birthday present! Never knew anything but fixed for a few years. Then I left it outside Woolies in Prescot and it was nicked. For a while I managed with a bike donated by a neighbour, until I was 14, then got the bates you see in my avatar pic. This had gears and was the first bike I raced on. 26" wheels, steel handle bars and chain set, yet still managed a "6". I swapped this for an RJ Quinn, with sprints and alloy chain set, but took me months before I went any faster.

I then picked up 2nd hand Mercian track frame, from a well known rider in the mid Shropshire whlrs. But, strapped a simplex rear and had a single 54 on the front. I think my bottom gear was 81" !

Did quite well on this hybrid, even rode the IOM 1 lapper on it.

I tried a couple of times riding this bike as a pure fixed m/c, but I seemed to go slower.

The Mercian, then got dismantled and went in the loft as I rode several geared bikes. But I never matched those times I did on the Mercian/gears combo. Years later, I'd got back into racing, but I only had the one bike, which was not dedicated to racing, so I got the Mercian down and had it resprayed, bought a cheap pair of wheels, one brake and some aero bars and used it for racing. It was a delight to have a clean bike just for racing. I found as well that it was quite consistent in my times, matching some of middle years when I rode gears.

Over the last 5 years, I've upgraded everything, new wheels, frame (a Nelson track) and continue to put in some good times. Managed a 25min 10 a few years ago, almost 40 years after my 23min PB. I've gone a bit slower the last few years, but breaking collar bones now and again seems to have that affect!

But at the back of my mind, I always think that gears should be quicker. So every now and again, I use my gears bike, similarly equipped, but I never achieve anything much different and usually 30secs slower.

This season, I am preparing a fixed and a gears bike. Not a top end bike, but similar and I hope to answer that question - "which is faster - gears or fixed" once and for all.

But for anybody starting to race, a dedicated fixed bike, with aero bars and good tyres, is a very cheap way of getting into time trials and on the short courses (10 & 25 miles) very competitive. Your times won't be much different from a bike costing 2 grand more.

My first race should be in a few weeks and then I'll start the gears/fixed experiment again.

Haven't been on the forum for a while but i was going to come back and post similar. I have commuted all winter on my 69" gear Fuji Classic Track in asbo orange. Crazy headwinds this winter.. I managed. Last week i swapped to carbon.. around 9KG with lights. Often the times are the same or slower. Or when i have a tailwind i up the gears and i beat the fixed times that's it tho. Honestly thinking of going fixed full time. Cheers.
 
I find I never get out the saddle when riding a geared bike.

when you people say 69" gear does that men 69 tooth gear? just a 69inch chainring is pretty large!

No, "gear inches" is an insanely archaic way of calculating your gear. Imagine you're riding one of those old "Penny-farthing" bikes. Your pedals are attached to the front axle. The longer your legs are, the larger your front wheel can be; the bigger your wheel, the faster you can go, because gear ratio is directly relative to your wheel size. So when we say "I'm riding a 69" gear" we mean we're riding a bicycle geared as if it had a 69" wheel. Cool, eh?

To figure it all out, there are many "gear calculators" on the web or downloadable. I have one on my Android tablet. But I usually use Sheldon Brown's calculator:

Be sure to specify "gear inches" rather than "gear ratio". Anyway, a 52t chain ring and a 20t cog will give you something like a 69" gear.
