Morning All 

Need some advice. I have a giant roam 2 with 700c wheels and recently it snapped a rear spoke on the j bend. Took it to the bike shop replaced it all happy. 1 week later (50miles max) it done another spoke on the j. The bike shop did warm me this may happen. 

Is it worth getting it rebuilt with new spokes or just buying a new wheel.

any advice be great

thanks

Tom

Depends on how nice wheel is, if it's a cheapo wheel it'll be not much more to just buy a new wheel, if it's got a nice hub and decent rim then it'll be worth rebuilding and keep it matching the front.

It’s just a giant rim and a hub that’s unknown what ever giant use. I guess I can buy a wheel online already built ? How do I know what would fit ?

If you're not sure then it may be time to go visit your LBS, maybe not the cheapest option but you'll get a wheel that works and have the cassette, disc rotors etc properly installed and set up. 

Plus if it goes wrong you can get them to sort it.

Something 700c diameter and 21-25mm internal width rim would be a decent replacement given the sort of bike and tyre width it uses. You'll need to know if it's a QR or bolt-thru axle though, and if it's Boost frame or not.

Bike shop quoted me roughly £60 to respoke it.

Theoretically a re-spoked wheel that has been properly handbuilt will be better than the original wheel as at that price point the wheels are machine built. The quality of a wheel depends as much on how well it is built as the components.

If you wanted something better you are needing spend more. For example, if it is a standard Q/R axle

Unless you are particularly heavy and hard on wheel when it might be worth upgrading the wheel if it was me I'd get the shop to re-spoke it.

I use it as a commuter bike not hard

on it. As for being heavy I don’t exceed the max limit on giant website for the bike. I use panniers on it but only ever have a cost in them and my dinner box.

Is it traditional QR road bike spacing?

If so, you can probably pick up a nice handbuilt wheel(s) secondhand for not too much.

Sounds like it could be argued either way.

 

I'd agree that £60 to re-spoke it is probably not a bad option if the LBS is decent at building wheels and the rim and hub are in good condition.

On the other hand in another few years will it be in the same position again?  Will the hub last that long? Will the rim?

If it was me (and therefore building the wheel myself making it quite a lot cheaper) I'd probably be shopping around for bargain parts and building a 32 or 36 spoke wheel.  But realistically even then I'd probably end up spending ~£150 even on it (Novatec hub, ~£20 on spokes, £50 for a rim). At which point £60 to rebuild it and it lasting a decent enough time seems like good value. The thing with commuter bikes is while spending money on nice stuff is 'nice'.  The most economically sensible option is almost always the cheapest one.

It's not worth rebuilding a cheap wheel like that - send it to the metal recycling bin.

Loads of good wheels available secondhand, or you could get one of similar quality for next to nowt. As shite as those wheels are, they usually last pretty well, depending on its age you may have just been unlucky with a badly built one.

I could buy a secondhand set and be in the same position or worse. Depends how you look at it. Unfortunately it’s catch 22. So the rear wheel will have done roughly 1200 miles. I’ve owned the bike from new.

I’m gonna speak to my lbs shop tomorrow see what the rim is like and the hub and kinda make that the deciding factor to weather I bother or just get a new one built.

TBH that's a decent price considering it's labour plus spokes. 

I use it as a commuter bike not hard on it. As for being heavy I don’t exceed the max limit on giant website for the bike. I use panniers on it but only ever have a cost in them and my dinner box. 

Are you sure you've not "been hard" just because you're not hucking to flat on the thing it's probably seeing pretty regular use and perhaps not frequent maintenance(?) Are you considering that the wheel is subject to You Plus any luggage weight daily? Most importantly have you checked spoke tension during that 1200 miles? By checked I just mean giving them a bit of a waffle by hand to see if any are loose or baggy feeling. 

Perhaps treat this as a lesson, whether you opt for the rebuild or buy a new wheel, checking spokes are still tensioned and not wanging about loose is a basic bit of maintenance that lots of people seem to neglect and then get a shock when a spoke goes ping. 

I assume you occasionally check you stem or crank bolts are tight(?) spokes are essentially the same, a simple threaded interface than can (and do) loosen with use and loading irrespective of how heavy you are or aren't...

Lack of maintenance I think not. I’m an agricultural engineer I know about maintenance this is no “lesson learnt”

The bike gets used daily. Luggage I carry a spare coat and my dinner box. To be honest the bike gets over serviced why wouldn’t it I need it reliable for work. If it’s wet I get it home dry it off clean what’s needed. the chain gets removed every 3 weeks cleaned, re oiled and back on while this is off all the cassette and jockey wheels get cleaned and checked. The wheels are often out so spokes and how the bearings in the hub feel is checked. Literally every bolt is checked to made sure nothing has worked loose. I can’t do anymore. 
It’s like anything mechanical you can service and maintain and replace but unfortunately even new or correct maintained parts can and will fail.

I also do daily check while riding to see if the wheels are looking out of true. The wheels are pretty dam straight and I know that if There is more wiggle or it’s not looking right when it’s turning then something is wrong. Hence how I know I’ve had a broken spoke or two. To be honest soon as I knew this was an issue I pushed

it home so not todo more damage.
