Forward fropouts and coaster brakes

[gaijintendo]

Hello team,

I have an old late 60's Falcon or Raleigh that I have been using as a single speed backup bike for commutes. I am in two minds as to whether to shift it or treat it to a few things.

One thing I was considering was a 2 speed coaster brake, and the dropout is giving me pause to consider my options. I haven't really thought about the mechanics in this; I was advised that running a forward dropout fixie was risky. Is the same true for coaster brakes?

Do the nuts up and it will be fine.

Same logic with the fixed gear? Would buying something like a Surly Tuggnut just be a way of hanging £25 off the side?

If you do find it slips, then you need one that looks like

I couldn't picture how that would attach. I had pictured the Tuggnut working like this: http://surlybikes.com/uploads/downloads/SUR_HurdyGurdy_Instructions_w.pdf

I had seen the type you have share a picture of, but I can't visualise how it would work with the bolt/backplate not seemingly being offset.

Thanks for the rapid assistance by the way.

The pictured bolts are for rear-facing dropouts. I would expect a coaster brake to be OK in forward-facing because the reaction arm would help keep it in place but I've never tried it.

That would be fine. It isn't a Tugnut though. It is a Hurdy Gurdy.

Yeah, I thought they were the same idea minus the bottle opener.

Cheers everyone for the help. Forgot about the reaction arm. That will presumably help a bit.

I like a nice Falcon. Just out of curiosity have you any pics?

You helped me last time...

It is a rescue hound. It was a serviceable five speed until I decided to strip it down and grease the bearings. I lost a couple from a cage in the rear hub, and had my first kid come along.... Single speed solution was to get it stopping a bit quicker, and use it as a backup.

It's still an unknown entity.

AFAIK coaster brakes have a torque arm that fastens to either the NDS stay or a braze on fitting on the NDS stay, they wouldn't affect the wheel laterally but would attempt to 'spin' the hub in the dropouts.

Nope - that will only work with track-ends (i.e. rear-facing dropouts with the threaded bit in the dropout slot)

There are chain-tugs that sit on the outside of forward-facing dropouts and have set-screws that push against the outer end of the dropout - BUT from experience they really aren't very effective. Like this

With a single speed freewheel and the nuts pulled up tight you should be alright - from experience even with loads of torque on the nuts it's quite easy to pull the wheel to one side with a fixed cog.

Here you go, the exact item forward facing

That's a nice system. It does look like the bolt has a hole to pass through.

For what it's worth, I am going to go by your initial suggestions and stick with my single speed and just bolt what I have on well. It works, it is simple... So why change it?

I was toying with the idea of grabbing an s2c Sturmey wheel I had seen on Gumtree, but I was just enjoying spending what little money i have before my second child arrives and poops his way through it.

Is it very cheap? I ask because the S2C hub has had an awful reliability reputation. The last I saw of @GrumpyGregry's he was carrying his bike because the hub was jammed up inside and wouldn't roll at all.

It was something like £70 for the whole wheel, and had been up on the site for a while. Was considering making a cheeky offer, but if it wasn't missing any parts I would say it was a fair price. If I had to disassemble it and add a part however... I would probably have to carry my bike too...

S2C = pos not fit for regular (daily commute) nor extended (long ride) use. imo/ime.
