alfine 8 for road use ?

Hi my mate needs a new drivetrain for his winter road tour bike and is thinking of a internal geared hub is the alfine 8 good enough and does it have a decent spread of low for fully loaded and high for a bit of speed. Also can you run one with a double set of rings up front. Cheers

Don’t see why not, double ring fine with a tensioner. The jumps might be too big for a roadie IMO.

I wish they’d release a close ratio alfine for roadies 🙁 I’d get one and belt-drive it.

If you do go down the dual ring route, you’ll have a mish mash of shifters for either flat or drop bars as there isn’t a ‘front’ shifter for Alfine…… that might not be the only problem though – are there issues with chain-line etc?

I use one for commutting. Range is spot on. It can get me up as good a hill as you can throw at me (Brecon Beacons, Newcastle, Wylam) without spinning out too much on a good down hill. So that’s a range of ~6 mph stood up in bottom gear to spinning out at 35-40 mph.

The chunky range is annoying though. Comfortable psnning speeds on ym gearing are 16 mph or 19 mph, where my average/happy cruising speed is somewhere in between.

The shimano alfine/nexus chain tensioner has a large spring and throw on it for exactly that purpose. You shouldn’t need it though.

you can have double rings – you need to use the alfine tensioner to take the slack up.

as for ratios you can use this to look at ratios etc

I have one on a Singular Peregrine setup pretty much the same as Jon Taylor’s (except mine’s shinier).
I’ve ridden home from the Lakes over Hartside Pass on it and its great.

Cheers chaps what size cogs and rings are you using btw

I’m using a 45t front and 18t (IIRC?) rear. It originally had 16t on the rear but I put the 18t on for a trip from Kendal to Swansea via the Brecon Beacons. I’ll check once home.

p.s. His is shinier.

I rode my fully loaded tourer up nearly everything apart from a 25% climb at the end of a 100Km day of ridding as I thought my head was about to pop. I also managed 40Km in an hour with a monster tailwind on another day of the ride. I was spinning pretty hard but not spinning out.
I’m running 18 39 I think (will check). Think I might drop it a bit if I tour again but unladen it’s fine. The only thing I found a bit annoying was having to back off almost to the point of stopping pedaling when changing down under load. If it was really steep it did feel like I was going to grind to a halt, but I got used to it.

I’ve said this before and at the danger of sounding like a broken record, the alfine needs thick spokes, otherwise the vibrate in the flange hole (fnar fnar) and snap at the elbow after x thousand miles of use!

I’ve used one for commuting/light touring for a year and a half now. Perfect for theses uses. Haven’t done any maintenance in ages! I use the JTek bar end shifter.

However, I’ve taken it on the sunday club run a few times and the gear jumps are annoying when riding in a bunch as 1 gear is too easy and the next is too hard at a specific constant speed.

Heh nice D, you’re turning into a roadie 😎

Oh damitamit I didn’t know bar end shifters worked with them 😉

45 front and 20 rear on my Roadrat. Perfect for commuting but I’d want to go a tad lower if touring, and maybe a tad higher (45:18 perhaps) if it was a drop-bar road bike.

I’ve got one of the Alfine tensioners so was thinking about using a double up front but haven’t got around to trying it.

firestater, only this special one works with it: http://jtekengineering.com/jtek_bar-end_shifter.htm

I got mine from PlanetX. Not sure they still sell them.

Ah not as good as hoped re the shifter , thanks all

On-one’s doing an amazing deal on the Alfine right now…
This…

…and this if you can’t be arsed to build a wheel!! 🙂 (costs 215 including all the gubbins)

Hey ir_bandito, what kind of shifter are you using there?

The alfine hub and bits is even cheaper at Rosebikes.co.uk (and it’s definitely the better 501 model)

shermer – it’s a Versa shifter. Like these

Thanks Jon! 🙂

Hey Mackem- that is phenomenally cheap!!! It does say that it’s only suitable for vertical drop outs though. Maybe there is a way around that?

Yep, you can buy the horizontal locking washers for about £4. Nice…

Nearly just bought a built wheel from rosebikes then realised it a 24 spoke one not for my fat ass lol
