Dear all,

I need to have a look at the freehub on my 4 year old (but only ~1500 miles) Bonty Selects. I can see what I presume is the Hex fitting inside the hub when I have removed the axle etc.

I know that it is bigger than 10 mm, but by sticking my 10 mm key down I can't tell whether it is 11 or 12 mm, and I seem to find conflicting answers on the net (nothing AFAIK on the Bonty site, thanks guys)

Can anyone help me? Much obliged if you can!

    Got a 12mm hex head bolt you could drop into the hex? 12mm is the most likely size.
    I've added a signature to prove it is still possible.

    Not to hand, but that is a good idea. I may just end up going and getting a 12 mm to try, the only way of getting an 11 seems to be ordering a Park Tool one on line as it is an uncommon size.

    Try Screwfix or other local tool supplier. You can take your wheel with you to a proper shop to try the size to make sure you get it right. Seen 10 & 12mm but no 11mm allen keys.

    It's a 11 mm allen key, I bought it to remove the freehub.

    7/16" is the same as 11mm.

    Can you tell me how (or whether) you managed to get hold of an 11mm wrench?

    buy a 7/16" as it is cheaper and the same size.

    Whilst I appreicate this is an old topic, I've blown the dust off it as I need to change my Bontrager Select Freehub. Having looked around for an 11mm hex key, the cheapest I coud find was not Park Tools or Wiggle, or come to that eBay, but was instead CPC Farnell who sold me an 11mm hex key, inc postage for under £1.50! Link here in case anyone else needs one.

    Indeed. And the best technique for leverage is to put the allen key in a vise and turn the wheel.
