Gearing for Single Speed

1 June 2015 - 11:25am
I have got to build a bike for my wife who wants to give cycling another go, after falling off a few years ago. It will only be used on the flat on various cycle paths around here and a single speed springs to mind as the simplest, least complicated and cheapest option, (I have most of the bits in the shed already). A SRAM Automatix hub is very attractive, but it's a lot to spend for what may be only a few trips per year. What gearing would people suggest please? I'm thinking that 60" - 70" would be okay. Any help appreciated.

Im getting very tempted to attach a very flexible pole a few inches short of an acceptable overtaking distance to the back of my bike. And then I'll attach a paint brush to it that's been freshly dipped in red paint.
Alternatively the cops could send a few riders out with go pros, and prosecute drivers for dangerous driving. Give the drivers points or a bicycle awareness course and the problem would reduce quite quickly.

If you haven't already done so, please discuss this with your local campaigner http://www.ctc.org.uk/local-campaigners/map

Yeah, I guess ... I'm still alive though and see them as increasing over m lifetime . Maybe I'll live to see them actually decreasing to levels below those when I grew up?

Efficiency to me, is the ability to go on indefinitely.

Efficient vehicles are vehicles that can travel using the least fuel possible. I can ride 100mile days back to back and think nothing of it physically, but then I don't try to do the 100miles as fast as I can.

Going back to hills, you need to get into a suitable gear (for you) and climb in comfort. Once down into bottom gear your cadence can't be increased unless you speed up. I find that I reach for bottom gear up a 1in6 maybe? Any steeper than that, my cadence has to go lower and lower and lower.

We live on a 1in4 and I have to climb it just to get home. I do maybe 2 or 3mph. The road is narrow with grass up the middle, so I only have a couple of feet width to go at that speed. 3mph in my bottom gear of 30r 28f = 24.5" is a cadence of about 40rpm. I cannot go into a lower gear, and I cannot go any faster when I'm tired after a long ride.

OK, I could fit a 34t sprocket and a 26t inner ring and be able to climb at 3mph at a cadence of 50rpm but I'm not complaining about my 40rpm.

and a medal

For cycling 48 miles! I seem to recall that I got a "oh good you are here at last, have you got your card" when I rode my 600k.

Hardly a farm gate was passed in the first 24 miles that did not have groups of riders fixing punctures in it..

You must have been bursting by the time you finished then.

A good nights sleep has been had.
And the search for the next sportive is under way ..... under a 100 miles though.

Re: Dangerous Cycle Lane Surface When Wet ALERT NCN8

I notified Cyngor Gwynedd online. They responded very quickly by telephone to explain that the A497 road between the 2 STOP signs at the level crossing is a length of 'unadopted road'* and it was the Ffestiniog and Welsh Highland Railways who had the 'cycle lane' road markings and surfacing done.

When I asked if Cyngor Gwynedd would have used a smooth paint for a cycle lane, the answer was no. They are passing on my warning and concern to the F&WHR.

*There are two strips of green shiny painted 'cycle lanes', one before the crossing and one after. The section before isn't on the 'unadopted road section' - if the highways engineer explained it correctly.

Isn't this part of the National To-Hell-With-Cyclists Campaign?

Having seen the new road / rail / cycle route layout at that junction, with very little room for the designer to play with, I cannot see how it could have been done any better. The trains actually have to travel down the road a short distance, so a standard level crossing is not possible. As for the road paint, it sounds like the sandy component is lacking, so notifying the Highways Authority is the right first step.

You're kidding, right? Get a good night's sleep (you should...) and you'll be raring to go again (not that I would know - you're one step ahead of me - but it sounds like a whole lot of fun)!

Hi,
Well if you can do it in atrocious conditions your next will be a breeze Keep us informed.

Re: Crane River Parks Hounslow & other London rides

The use of the Cavalry tunnel - which was modified as a cycle underpass of the railway many years ago. Unfortunately there has been legal wrangling between ? Network Rail and LB Hounslow which has prevented the route being made official. LB Hounslow have referred to the connection as a Holy Grail.

FORCE are a local pressure group and their leaflet represents an aspiration.

Re: Is it OK to stop traffic with a Pelican/Toucan?

31 May 2015 - 9:45pm
A similar situation applies at the west end of Kingston Bridge . The cycle track over the bridge terminates vaguely but a toucan crossing allows cyclists to get into the correct lane for the roundabout straight ahead. Perhaps the Highway Code should give advice.

True.

Re: Is a cadence sensor worth it?

Hi,
I maybe started to misrepresent your average speed from memory, I couldn't look for the info you posted as I would probably struggle so I guessed a bit.

Yes we are all different and maybe its in our genes what pace you set.

Your own admission is that you have a low cadence so yes as a regular poster you are more than likely to be quoted, certainly no slight there

If you look at what I posted as I slow down and go up hill my cadence is slower.
So I am on that point opposite to you.

Re: Is a cadence sensor worth it?

I think it's more than that MickF - I think you are at the lower end of what a "typical" range.

And no-one doubts that you put the miles in and have actually tried different methods. It's one of the most convincing "it varies by person" comments...


But - you are generally aiming for endurance, not outright speed, so define efficient? Does efficiency allow speed or endurance.

That's the gotcha - people say most efficient without actually saying that they mean most effective at <unknown target>

The Arrow ... my first Sportive.

31 May 2015 - 8:43pm
My first Sportive.....
I had a great ride.
Soaked to the skin and blown all about.
Good company in fits and starts.
I usually ride alone.
Lots of organisation, lots.
Timing, chips on our helmets, signs every where, a feeding station, "free" stuff.
Massage, a burger van.
Hundreds of punctures !
The plastic fantastic brigade love to fit expensive unsuitable tyres.
Hardly a farm gate was passed in the first 24 miles that did not have groups of riders fixing punctures in it..
On my finish a drink, an energy bar and a medal.
Lovely Lincolnshire at its wet best.
48 miles of fun.

£25 !!!

And my last ... at least I gave it a go....

Re: Scotrail Online Cycle Place Booking

I recently (2 weeks ago) booked bike spaces on a Scotrail train via the east coast website (actually East Coast Virgin Trains). You do it on the seat reservations page. The train was Fort William to Glasgow.
