Shortening a QR Skewer?
View Full Version : Shortening a QR Skewer?
I have just purchased a set of Hope QR skewers from Wiggle for my Road bike. Unfortunately the rear
one is too long, i.e. the thread doesn't go far enough up the rod to tighten the wheel. I guess they
are designed for a mountain bike?
Now I could of course just send them back, but I really like the design and colour (metallic blue).
1. Would it be possible to continue the thread down the rod and then cut off the excess?
2. Any idea what size tap (or is it a die?) I would need to do this? Are they expensive?
3. Would it be difficult due to the hardness of the steel?
4. Could I take it somewhere to get it done (best option I guess?
Any advice would be appreciated.
Thanks in advance.

That's not very thoughtful of them!

Probably (135mm).

I would think so. I use some Tranz X MTB skewers on my 130mm road hubs by simply screwing the rod
through further: there is enough thread fortunately. Be very careful if sawing any excess rod off
(may not be necessary anyway) as they can bend easily.

Die. I don't know what size.

I doubt it'll be the hardest of steels.

I think it would be a die rather than a tap that you would want BUT I personally would worry about
cutting more thread to extend an existing one as there is a risk of creating a "thin" area of thread
that could slip - especially as retention of the wheel in the fork dropout is rather important.
Thinking laterally for a moment .... how much to long is the axle ? Is if feasible to put some sort
of spacer at the other end (i.e. not the turnover lever end) to compensate ... obviously some care
would be needed with washers but it may be worth a look (I've done this with a seat pin QR but the
importance is not quite as fundamental as a wheel)

Shimano are M5 thread, I'd guess this would be a standard for all or most skewers. You will need a
die, £11ish to cut the thread and a die-stock £? to hold the die and provide leverage. Or you could
use a die nut, £25ish. You might find them cheaper at a bona-fide tool merchant eg Cromwell Tools
www.cromwell.co.uk browse through cutting tools etc.
Meself, if I had no access to the kit I'd return the skewer and swap it for the correct one.

You need a friendly local engineer who isn't busy ;-)

Is it cut with a die or is it rolled (similar to the end of a spoke?)

Nope

Get one the right size - shouldn't be too expensive - I have some in the shop for £1-25 but I'm
incapacitated at the moment :-(

Aaaargh! If it's rolled beware, the unthreaded diameter will be less than is required to form a
decent thread (rolling forms the metal that would be cut away conventionally into the peaks of the
threadform) - check by using a vernier or micrometer the daimeter of the thread, and then check the
diameter of the unthreaded portion you wish to thread. If the unthreaded portion is less, don't
attempt it.

Mmm, carefully taken into account these thoughtful replies I think I will give it a miss and
return them.
Thanks for all your help guys.

That sounds to me like a sensible solution. The other solution that occurs to me is to ring Hope -
they have a reputation for being an approachable company.

What's up, Sandy? Hip playing up?
You'll be needing to get well before Wednesday night!
Best wishes.

This is what they recommend for the special skewers used for BoB trailers and I have done precisely
this to use mine with a 126 OLN rear end.
Of course, this now means I can't use it with my mountain bike. Blean :-(

Op. and the aftercare was fantastic and the pain has gone but I'm still a bit restricted in movement
- I can't run up and down the stairs :-)
> You'll be needing to get well before Wednesday night!
I have my high chair suitably positioned and the New Year (liquid) shopping has already been done -
and sampled.
Unfortunately SWAMBO slipped a disc whilst putting on my surgical stockings and she is now in the
local hospital in extreme pain.
2004 must be an improvement !!

Good news - I'm delighted to hear it.

Good planning.

Bad news. I know that pain. :-(
> 2004 must be an improvement !!
I'll drink to that. Here's to rapid and complete recoveries for both of you!

Ouch! pass on my commiserations to her!

Best wishes for it.

Before shortening my BoB skewer I did try this, but was rarely able to get the q/r tight enough to
keep the wheel properly disciplined except under the gentlest of acceleration.
