Rear gears no triple or double on the front - road bike

Do they still sell road bikes with just gears on the back and none on the front ?
And/Or
Is it possible to change my chainset on my Giant SCR3 to a single 42 - or 44 and still have 8speed gears on the back?
The reason I'm asking is that some of the feedback from my new repairs was that the bolt connecting my front mech to the thingy that keeps it on the frame is broken and the shop had to use a bigger bolt to keep the mech on and prevent it from moving. Eventually this will wear, evil will happen and the mech will need to be replaced.
With recent learnings about gear inches and single speeds I was wondering if its possible to simply reduced my chainrings to a single?
Not that I'm going to do this, I'm just curious?

Yes. Just remove a chain ring, front mech and gear cable. It's just the fromt half of a SS conversion!
I'm going to toy with this idea and eventually mention it to the bike shop man who will look at me like this: :shock:
That said I do somewhat think this could be part of a larger project with a better frame... we'll see.

Sorted.

It would also be much cheaper to replace the front mech than buy a new chainset.
Very true. When enthusiasm take hold I loose sight of practicality sometimes. :oops:
I think my middle chainring is a 39, don't quote me I need to go check.
A quick use of Sheldons gear inch calculator is telling me that I would prefer to have a 44 combined with my 23-12 cassette. That way I could comfortably use the first 5 rear cogs before I got into the 80s in terms of inches.
This not considering any hills on my commuting - it is only London...

Good luck

to stop the chain falling off.
As Brun suggests front mechs aren't expensive though!
That said, if you try this, said cross bike has 42 ring and 11-25 and is absoultely perfect for hacking about town.
If you do this, you still have the bailout option of shifting between rings manually (with a bit of practice you can do this underway). All you need to do then, is switch your middle ring for a 44 (or whatever you come up with).
I'm now running a 28/40/50 I found on Ebay with a 12-21 cassette and the middle ring is good from a standstill up to around 28mph, so I almost never touch the front changer.
Edit: Definitely don't need a front changer just to stop the chain falling off; when I was a poor student (and before you could buy used front mechs on ebay for less than a fiver) I did exactly this...
To run 8 out back you will need a chain guide of some description to stop the chain coming off at the extremes of the cassette. You can bodge one out of your rear mech, set the position using the low limit screw.
The other option is a hub gear out back for up to 14 gears.

front mechs aren't terribly pricey, 105 is around the £30 mark fitting them isn't a issue setting them up is a bit more of art but still doable.
to be honest I don't use gears much in london never a need to get out of the 50t and tend to be in one or two gears, certinly central there is argument for SS.
Or just do it proper 70s stylee and run a five speed cassette. Assuming you can still get such things, they'll probably cost buttons and as long as the overall range is OK the gaps, whilst bigger than they would be on the 8, will still give you far more control of your cadence than a single speed does.
Mind you, this is all heading towards a route of non-indexed, downtube shifting elegance which some folk might get sniffy about
In London, unless you live out South East or around the greater London boundaries/outskirts (try riding around Crystal Palace and tell me London doesn't have hills) you really don't need a bailout chainring but would need some options on the back. IMO

My current commuter is downtube (or in the case of my front mech downtube + lean down and push) based shifting.
A bazillion times smoother than the 105's on my other bike - No clunk, no jump, just a quiet tick and in. Peachy.
*sniffs*
front derailers are just brute force, so no elegance I do understand where your thinking I would just say beware of costs, one other option is to sell this bike and get one you'd like for the commute?
I do love the swift, faffless sweep through the gears the old style shifters provide - except, as I found this weekend, when you are battling up Wrynose Pass where there is enough to worry about without flailing around with the downtube
this is exactly what my pub bike has on it, a single 39 up front with a 11-32 on the back. I don't use a guard (although a dog fang would hardly break the bank) and it's never fallen off. And I've got gears from 32" to 95" although I'll grant you there are some gaps.
Bar-end (ratchet) friction shifters by SunTour, coupled with a Cyclone rear mech. This was the peak of shifting technology and is yet to be bettered. No clicks, no faffing, no over-complicated integrated stuff, no need to take your hands off the bars.
It's been downhill ever since they invented STI :-), and I don't mean that in a good way....
Pass me my pipe & slippers, and I'll tell you about the time I watched a Shackleton fly past below me when touring up by Inverness.... :-)
Cheers,

But I don't understand what is broken in the first place - not sure how this can be a terribly complicated problem. Piccie?

Lol - I have a Raleigh Record Ace with Cyclone GT derailleur. Not many deraileurs made today that are as light.
And I will even admit to the vanity of thinking it looked cool
Me too. Haven't used them for years but got right back into them, and have a cheeky bit of Dura-Ace on a £650 bike:
There's something quite satisfying about the clutter-free bars and brakes that are just... brakes.
Looks alot nicer too. I like it...

If memory serves you already have a SS bike sitting at home so why not just commute on it for a few days and see how it feels. If the gearing is wrong, well it's not expensive to sort that. If you want to do hills you have geared bikes and there's no reason you need gears on your commute...
