    Looking for some advice from those of a more technical persuasion...

    I've just bought my son a new mail-order bike. When I came to take it out of the box I spotted a hole in the Grip Shifter


    This didn't look right to me so I fired off a email to the technical department. This is the response

    The hole that you have spotted on the gear shifter is actually where the gear cable is located, it slides through this hole and is kept in place by the nipple at the end.

    Please be assured that there are no components inside the shifter that could be subject to damage from water in the unlikely event that any makes its way into the shifter.

    What do the people think? The bit about the hole being where the cable slides through doesn't sound right to me.

    Makes me wonder if they even clicked on the link to view the photos. They were an link rather than an attachment.

    Or am I overreacting?

    Any advice welcome.

    Thanks

    In the first picture is there a rubber plug or something blocking the hole which you've removed in the second picture? Might be my eyes but it looks like in photo one there's something sticking out next to the CC and in the second it's a depression in the surface.

    The only grip shifters I've dealt with are Shimano ones which have the cable end accessed by removing part of the plastic covering. This one doesn't look like one of those - if it has a brand and model you could look up the instructions online (if available) and see if that turns up anything about where the cable goes.

    It's hard without having it in my hands to look at, but I think that is where the cable goes. It looks like when you turn the barrel back it'll pull in cable to go to the lower gears - am I right in saying the gear numbers stay fixed and the small white arrow moves to indicate what you've selected? If so it would make logical sense for the cable end to be there.

    One thing to try is to see if you can peel back the rubber covering. In the second photo, going left to right, there's the black part with the numbers on it, then a white part, then the rubber. I think if you got a thin screwdriver between the rubber and the white part it'd easily separate and pop back to reveal the cable end (sorry this is very obvious picturing it in my head but is a pain to explain).

    Do you poke the bare end of the cable through it from the outside, so that the swaged end is then trapped by whatever traps it?

    Thanks - I think you've sussed it.

    It is a SRAM 3.0 COMP

    Here are the Technical Instructions

    So it does look like you feed the cable through that hole Feed the new cable through the
    cable entry and out the barrel adjuster.

    Thanks for the quick solution - the helpfulness of CCE strikes again.

    I'd better go and put the pedals on it now...

    I was forever confused by which way each pedal tightens, and spent many an afternoon trying to 'loosen' a 'stuck' pedal by wrenching it with all my might in the wrong direction, thankfully I saw a bit of wisdom which is both pedals tighten the same way the wheels turn.

    Fun story....I saw on Bikeradar about someone who had read the explanation about how pedals are threaded to 'self tighten' from precession. He used a pedal wrench to get his old pedals off, but then put his shiny new ones in just finger tight thinking if he went and rode them they'd tighten up. I recall an expensive lesson was learned shortly thereafter.

    That's another good way of remembering the pedal puzzle.

    I just think of the 'right pedal' tightens the 'right way' (and the left one otherwise).

    Although I admit to mucking it up when the bike has been upside down and thus confusing my sense of left and right... :-/
