Hi all,

Have just bought a Flyer and want to ride it fixed.

Holborn branch of Evans reckon there are chainline issues when set up fixed. Chap reckoned it was 4mm out...Is this true?

Anyone here riding the Flyer fixed and do you have problems?

Cheers,

John

    Haven't heard anything, but why would chainline be different when riding fixed compared to free?
    I'm a beginner when it comes to fixed so I guess there could be a good reason, I just can't think what it might be.

    I have a flyer too with the intention of converting it (I've got the bits, just haven't got round to fitting them yet). Will bear this in mind when I do.

    I was hoping for a solution a bit less drastic. Maybe different brands of cog would give a different chanline, etc? Or spacers?

    This is all new to me so please be gentle...

    If it was purchased at the Holborn Evans, then they ought to sort it the f**k out whatever needs doing. It's not 'fit for purpose' if the chainline is out on a stock fixed/free bike.
  • The Flyer's rear hub is fixed/free; therefore the supplied bottom bracket should give correct chainline with <i>both</i> sides (standard track chainline being 42mm). If it doesn't, this is something that the shop which supplied it is responsible for sorting out.

    In order to be armed with knowledge before tackling the shop... the method for measuring front and rear chainline, and everything else you need to know, is here: http://sheldonbrown.com/chainline.html

    Fine tuning of chainline is possible by using different sprockets, or by flipping them. E.g. a Miche splined 3/32" sprocket can be as little as 5.15mm from the hub thread shoulder (depending on which way round you mount it) and an EAI 3/32" sprocket will be at 7.13mm

    Ok - I went to pick up the bike from Evans today, and true enough, they say there are chainline issues. They had tried for an hour and a half (apparently!) and failed to get it to line up. I'm not sure which brand of fixed cog they were using.

    Apparently Genesis are aware of the issue and they have given me a phone number of the parent company Madison.

    So, I was all ready to ride home with standard freewheel setup and noticed there were several scratches on the frame that I'm pretty sure weren't there when I test rode the bike.

    I asked if they had a new one, and apparently another branch had one but it wasn't made up. I asked if they could make it up quickly and I go and pick it up from the other branch.

    Apparently, "computer says no" and they cannot do that for some reason.

    Arrrgghhh!!!! I almost asked for a refund and threatened to take my money elsewhere... but I'm desperate for the bike and apparently I can pick it up Monday.

    I will never buy anything from there ever again (Holborn branch, and Rathbone seem just as flakey too....)

    I don't understand what's going on! Are there issues or are Evans just incompentent?

    Can anyone recommend a decent bike shop that can set up my Flyer fixed for me so I can use both sides of the hub?

    Thanks.

    John

    My mate is buying one from Mosquito on Essex Rd and they offered to sort it out when he decides to convert it to fixed...

    I took delivery of a Flyer last weekend, set up fixed. The chainline isn't entirely straight - the chain ring is further out from the bike than the sprocket. I'm not sure how hazardous this might be(!) but it does cause the chain to rasp a bit when in use.

    I'm new to the fixed game, but I guess I'm hoping that it can be rectified just by putting a spacer inside the sprocket(?).

    brick lane bikes will fix it for you.

    it seems odd to buy a new bike that doesn't work properly.

    get a fillmore instead.

    Is this a common problem nowadays with manufacturers taking what is essentially a stock 'geared' frame and stripping it down to suit the growing fixed market? If so, is it a problem that the mainstream manufacturers have created for themselves or does it afflict the more specialist companies as well - I'm assuming that it doesn't.

    One of the attractions of fixed bikes is their simplicity, so it seems bizarre that the bike has to be returned to the LBS to sort out the chainline everytime the customer wants to 'flip' the wheel.

    Cheers.

    I don't think the problem's to do with the frame; whether not not they're stock, 'geared' etc doesn't make any difference, seems like it's to do with the hub and crank/BB. Getting a good chain is easy, with the right parts!
