Broken a spoke, drive side on my rear wheel.

It looks like it's difficult to buy spokes singly in any case, so how much will a LBS charge to fix? I'll bring the wheel in bare..

Would you ride on it? 1 mile, 10 mile, 20 miles? It's an Alexrims wheel, I think from a Rockhopper or similar, so probably not exactly high budget

LBS will charge, what, £10-15 to fit a new spoke and true it up. Easy enough.

I buy spokes from www.cyclebasket.com - I've built up a few wheels using ACI DB spokes and not had one break yet.

If you want to fix it yourself your local shop should sell you a spoke for no more than £1. You'll need to remove the cassette to get to the spoke so will need a chainwhip, lockring tool and spoke key. Spokes are sol din boxes of 72, 100 or 500 so not normally available mailorder individually.

This.
But if you intend on breaking them often, it is worth the investment.
You also need to measure your spoke pretty accurately as they are not of standard size generally.
Ask the LBS to cut you one to size.

Yeah all the local LBS are quoting 'at least a few days' to fix. I might as well buy a few spokes and a key. Is it simple enough DIY? I assume it won't go out of true if I just do the one spoke?

You need to measure your spoke, and then your LBS will sell you one for between 50p to a couple of quid depending on what spec it is, (Single of double Butter, Black or silver, Aero, etc etc).

You need to measure the spoke accurately, ask at the shop if your unsure.

I'll take the broken one in with me.

Do I definitely need a spoke key, or can I use a screwdriver on the end within the wheel, once I take the rim tape off?

How old is the wheel?

Can you true it on your own?

I'd take the whole wheel in and get them to true it as well (normally be included in the £10-£15 for the spoke replacement), might save a few more spokes in the next few months and provide a much better wheel all round at the end of it.

Often the end of the spoke pokes proud through the end of the nipple, so you might not get a screwdriver on.

Typically when building a wheel you would whizz all the nipples on a few threads with a screwdriver then do the actual tensioning with a spoke key.

Get a new nipple with your spoke, so dont worry too much about damaging the old one. If needs be a very small adjustable spanner will get the old one out.

Get a couple of spokes, a handful of nipples, and a spoke key to suit.

Bear in mind that your wheels could have upto 4 different spoke lengths (front, rear, drive side/non drive side) depending on what they are. Spares are always useful and they are not dear.

I fixed mine myself. Took wheel into shop, they sized the spoke and I fitted it in 5 minutes. Job done.

The main thing to addres sis why the spoke broke i nthe first place. Generally it is indicative of either too low or too high tension in the wheel. Being a fairly new wheel off a Rockhopper I'd say the tension is too low as all of Specialized's wheels are shockingly poorly built (except higher end Roval ones anyway). I'd say you need to increase tension on wheel by adding a half turn on each spoke too but the only way to check it properly is with a tensionometer which is an expensive specialist tool and decent bike shop should have.

New spokes .. £2 each! (apparently the black ones are more expensive..)

Fitted them last night and set the tension to equal "twang" all around. Rim seems to be true from what I can see.

Should there be any play at all in the spokes ?

Not sure on the "twang" but there should be some give, "twang" to me sounds far too loose, but then I've never trued a wheel, I'm just going on what I get back when I take my wheels into my LBS.

Dammit, another one frown

Weirdly, it broke as soon as I took the tyre off to fix a puncture, and the wheel is now out of true (cycling 8 miles home was interesting)

Could it be because I'm running 1.5" City Jets at 80psi? I've done about 100 miles since replacing the previous two spokes.

New wheel time, or just keep replacing them? At £2 each, I'd be up to a new wheel quite quick!

Just get a second opinion down at your LBS, used to use my mtb for a winter commute on 1.2 110psi tires and was prone to a spoke or two when tackling the pot holes & kerbs at speed on a hard tail during the daylight saving months. The tension in the spokes from your previous discription didn't seem too high so may be it just needs good true and tension check.

take it to a good bike shop ,spokes usually break when they are over tight or laced wrong/out of dish

If you still fancy doing a full true and tension check on your own have a look at this simple guide.

Thanks for that video, very useful.

I think I had the tension right (from the pitch of the 'twang')

However, last time, I didn't squeeze/pre-stress the spokes at the end, so I wonder if this may have caused a failure. Could that explain why the spoke broke as soon as I took the tyre off and laid the wheel down on the floor?
