    New AC Ordered.........some queries

    I have recently ordered myself a Helius AC and am now purchasing bits in preparation for when it comes.

    1. Deep insert headset - is this really required or will i be OK with my chris king standard headset off my old Turner 5 Spot?

    2. I will be fitting a Rohloff hub - what position will i require the chainring to be in on the front chainset e.g. middle or large? Reading the Rohloff notes it states that it has a 54mm chainline requiring the large chainring to be used. If this is the case how do i run a bash? Is this just spaced off the large chainring and bolted through with longer chainring bolts?

    3. Another Rohloff related query but this time for the requirement of a chain guide. Will i need one? Can anyone who runs this setup give some advice please? What makes/models are available and how is this setup in conjunction with a bashguard?

    TLR: chaingrowth, can't tighten the chain like you do on a hardtail or Nucleon AM.

    I think it depends on how you ride it.

    1. It'll be fine, but the HT will not be covered by the warranty

    3. I don't use chain guide and I've Rohloff doupouts. Just in very hard riding conditions the chain can jump out... I would advise a use of a DH Rohloff tensioner, which is shorter a stronger.

    Also think about using an e13 or MRP 1x9 guide. Simple to fit behind the BB cups and will give you all the security you're likely to need.

    Jason - I have run my Heilus AM this way yes, with a 1x9 MRP guide. I found that they work reasonably well but I did lose the chain off the bottom of the ring quite a bit. That's not a problem as long as you don't pedal backwards when it happens. If you do, then the chain torques against the plastic top guide and flexes it inwards enough for the chain to then jam between the back plate and the chainring.

    Consequently I gave up on them and I now run a full e13LG1+ on a 1x9 regular transmission set up.

    However I am aware that I am a bit of a hooligan and I seem to suffer from losing my chain far more than other people do.

    Sorry to highjack your thread , but will my CC (see other recent thread) will covered by warranty with a regular headset? Or, as it is second hand anyway, is there a warranty?

    Nicolai provides a five year warranty on all their frames and while there may be some that aren't included in that, I am certain that the CC is.

    Rather uniquely, this warranty is transferable. I don't know of another bike company, or come to think of it, any other company period, who provides a transferable warranty.

    AC upwards require the deep insert headset for the HT to be covered under warranty

    ah, so the question from both the OP and myself is - do we need a deep set headset to satisfy warranty??

    1. Deep headset is required and strongly recommanded, i have customer who flared the bottom cup of the headtube due to low insert headset. actually for your frame, you only need a minimum 22mm on the lower cup

    2+3.. Most of our set ups uses 32T chainring with a 13T rear cog and DH tensioner. ( i.e. middle chainring) we might have to work around the BB spacer to make the chainring go closer by +/- 3mm(1spacer) towards the frame. ANd usually the chain line is fine that way. run a bash and just a to inner guide to make sure the chain downn fall inwards from the chainring.
