Freehub damage?

[Mick F]

In what way is it Custom?

[[XAP]Bob]

Capreo was discontinued, the hub goes down to 9teeth (needed to get decent gearing on a 20inch wheel without a whacky chainset)

So ICE have their own made specially.

[Mick F]

Ah, I see.

It's a pity that the body is so weak.

Yep - but 9-32 is quite useful (with a "normal" 26,36,48 up front.)

26/32*20 = 16 1/4
48/9*20 = 106 2/3

I can't help thinking that small wheeled bikes need some sort of "multiplier" in the drive train. Not that 20" is that small, but it does limit the top gear available with a normal cassette - hence the 9t small cog.

This was my quandary with the Raleigh Chopper. I could have just fitted a new hub and derailleur but with a 20" rear wheel, I'd have been in the same situation as you. Consequently, I left the SA 3sp where it was, added a double sprocket and fitted a 52/42 chainset. I ended up with 22" to 76" not quite high enough for me, I could have done with 90", but I had a low enough one to get me up the hills!

Hub gears have to be the way ahead to get higher gears, especially as you can get caught out in the wrong gear. On an DF, you can just spin the back wheel and change gear, but on a Bent, it's not so easy. A hubgear would be just a flick of a lever.

[[XAP]Bob]

I agree - hub gears make a lot of sense...

I've just seen this:

This looks just like the OPs!

Really? 53 x 11 works for me, but then I've never seen the point of pedaling hard down hills....

Jackshafts are used, but the added complexity is probably unnecessary.

A larger chainwheel and or a hub gear with smallish socket is a much simpler solution.

Yes, whatever system of sprockets you use shouldn't produce damage like that. I appears that your sprockets aren't a good fit to the splines. I reckon your freehub unit is fit only for scrap. Sorry.

I have a couple of Campag rear hubs, both of which have done well in excess of 7,000 miles each, and neither has any damage at all.

That's the response I was looking for - direct comparison with other hubs. It's concerning, but I shall see what the nice men at ICE have to say about that. 600 miles isn't very far in my book...

Anyone else taken their ice cassette off recently?

I had mine off last weekend no problems done about 2,500miles on it. It's a Shimano Tiagra.

Just edited; I realised that I had a spare new hub identical to the one I've got on so I've just whipped the wheel off to havea look the first pic is the hub that is on the bike and the second is the new hub

That on a big rear wheel then (i.e. not the custom copy of a capreo)?

Yep Big wheel 700 23 Chrina Rigida

[Mick F]

I see the Tiagra has a black cassette holder.

Is it steel?

Good question! I'll go and have a look.

Malc

tried the magnet test, steel.

Tried a file test appears hardend, mind you I didn't try to hard as it's brand new

Sorry for getting you out on a Sunday evening!
