Hammerschmidt owners

I red in a test somewhere that the hammerschmidt's pawls engage more easily than the rear hub on the test bike being used.

Did I understand this correctly in that the hammerschmidt chainring can effectively freewheel?

If it didn't then surely it'd be like riding a fixie? You'd havee to pedal 24/7.

Scratch tha above comment... i've see what you mean now.

I guess it needs to to be able to "change gear" although the HS is supposed to have seemless shifting.

nicklouse

having read the manual it does not say anything about it having a built in freewheel mechanism and i dont thing it is big enough to have one.

I have one on order but have not used one yet.

will dig about a bit more.

I shall also be buying a HS soon.

I can't see why a HS would need a freewheel.... surely you only need one and thats on the back!

ONly problem I can see with a HS is that they're a P.I.T.A. to fit. I've read many times that the BB need to be faced perfectly as its a very precise piece of machinery.

I'll have to find a new LBS if I do get one lol!

caN The HS be fitted to most new frames. realy fancy one of these on my new build next year

It has to have the correct tabs. Some FS frames aren't compatible becasue of the location of the shock and how the frame pivots.

The HS needs both the BB and the ISCG (and 05) tabs facing to certain dimensions.

any frame that has ISCG 03/05 mounts (adapters do not work).

XxxBFGxxX

what about the orange blood frame would it fit on that.

cheers

nicklouse

does it have ISCG mounts?

Do you know how much they cost, I would rather spend the extra £700 on a higher specced bike... as I said to bigbenj eariler, it's all a bit gimmicky for me, with absolutely stupid prices... it's OK if it's on a bike bought as a whole, or for pro's, but to buy it to add to a self build is financial suicide

The Rookie

When you consider its effectively just a 2 speed sturmey archer hub inside the crankset it is hideously priced, I predict that in 2/3 years it will be a more realistic £300.....

I dont think you are paying for the tech and work involved, more for the benefits it brings. I run rohloffs over derailieurs for many reasons, mainly the ability to block downshift without pedalling. If you've never had that option its very hard to understand that benefit. The HS also offers this facility, but without having all the weight slung out over the back. The only thing that worries me about the HS is the width of the BB and cranks. The Q factor is 1mm greater than my current cranks, but the crank arms are virtually straight meaning that it will be much easier to catch your heels or ankles on them. The price, while high, is swallowable if you are building a bike of a high enough standard to justify the need for one.

I really want one, but get the feeling there will be a mk2 within the next year or so. I will wait and see I think.

Thanks for the answers to my original question though.

the hammer schmidt does freewheel yes and paired with a hope hub sounds awesome when you do stop pedaling,, makes a good get of the way noise to hikers...

they shift instantly as soon as you click the shifter it changes, pedal forwards backwards or don't pedal it still changes..
it changes under load ie putting full power down uphill it will still shit instantly,..

one minor gripe casue of the freewheel thingy you can't back pedal the bike (to lube the chain) it will back pedal but say every 20 turns of the pedal will equal on full rotation of the chain and if you hold the chain in a rag to wipe of excess lube then it wont back pedal it just freewheels and clicks,,,

it is pretty cool and will change the way you ride.. my brother who owns it struggles when he gets back on his hardtail with a front mech, the instant shift when you need it to power up that climb or through that rock garden,.. the clearence you get with the tiny plantery gears...

nicklouse

delcol
is that in all both gears?

delcol

nik...

yeah both gears.. one back pedals better than the other not sure which one it is but like i said its like 15-20 turns of the crank equals one full rotation of the chain.. and you can't hold it in a rag to wipe....
have to lube it forward pedaling, lift the rear wheel off the ground or turn bike upside down...

ride_whenever

I'd rather go for one heavy gearbox! Either a gearbox bike or a rohloff, I cannot see the point of this with two gears! The change in weight for going up to more is small.

I think I'll stick with derailers ;-)
