Hey guys,

Had my Specialized Hardrock (2011 model i think) bike for 4+ years now,Still a great bike and i use it daily to get too and from work.

Its now developed a problem where When i peddle the chain keeps slipping,Not into another gear but just slips then i can peddle for a bit but then will slip again eventually and seems to be getting worse, i don't know if its the teeth on the chain cassette is just worn,or the chain itself is a problem?

I don't think its the chain because it doesn't seem loose in anyway.

Anyway as i know nothing about bikes,How much do you think something like this would cost to sort out?..rough estimate?

Assuming you haven't already got the required tools, it'd cost you ~£39 to get a new chain, cassette, cassette tool, chain whip and chain link remover:

So if you want to do it yourself, it'll be cheaper than taking it to a shop, you'll get to keep the tools afterwards, and you'll learn some bike maintenance :)
 
It could be that the rear wheel is loose in the dropout. I've had issues with the chain slipping on my mountain bike and it turned out the driveside nut was loose, so when I put the power down it was enough for the wheel to get pulled forward and the chain just slipper on the cassette.

Could be, but at 4 years old as a daily commuter, unless any maintenance/servicing has been done in that time more likely to be worn drivetrain I would think.

This :) I'm all for DIY!
 
Thanks to all for the reply,Not keen on the idea of D.I.Y..i dont have a bloody clue lol.

I emailed a local bike shop just after i made this thread,they have not got back to me though..give it another day if not its their loss of business.

See i wanted to see how much they charged for this kind of repair before i took it in because if he says something like £100 ive wasted my time taking it in,Their time looking at it (because i wont pay that much,Might as well invest in a new bike.)

Il see if they reply first..i have a bike shop literally right around the corner from me but they're known to be dodgy so i wont go to them.
 
Yeah that looks a bit too complicated for me lol,Maybe not the cassette part but the chain and everything...nah,Best i take it to a shop,At least then if anything goes dodgy i can just take it back and get them to sort it.

Meant to ask in my lat reply,What can i do about my knees!

My knees have started hurting lately and i think its because of the bike,I have the saddle up high (as im quite tall) high enough so when the pedals low my legs fully stretched but no matter how i adjust my saddle hight i still get dodgy knees.
 
You'll either have to pay a fair bit of cash to get a bike fit or watch some YouTube videos about how to set your bike up properly ;)

Do you use flat peddles or some kind of clipless?
 
uv posted them but they look like they're probably fine to swap to me. Might be best to wait for confirmation though as I'm not that knowledgeable when it comes to MTBs.

The reason I asked about the peddles is that once you go to clipless you need to pay even more attention to bike fit or risk injuring yourself. The benefits are worth the hassle though.
 
Yeah i wouldn't go clipless anyway,Just prefer the standard ones..and its not as if i do long runs on the bike its only a mile there and back each day to work..but in that 4+ years ive had the bike the only thing that's been changed are the brakes and tyres for better ones.

i think if i replaced those parts he listed i could get another couple of years from that bike.

@Topgun,Those parts link you provided are those the proper parts for my bike? so i can straight swap them?

They are, they're the exact same parts that are on the spec sheet for your bike. Tbh, any 7 speed cassette and any 7 speed chain would do the trick, but you'll find that new 7-speed stuff is actually quite hard to get hold of nowadays.

Depends what shifters you like I suppose (thats what I decided upon), I ride SRAM Apex which comes in equivalent to Sora/Tiagra. I like the double tap shifters rather than Shimano's where you move the brake lever entirely. The rest of the groupset is decent as well, will last a while although troubleshooting is tougher as most videos are suited to Shimano setups (not much difference in it though!).

But best to give them a test run, some prefer Shimano and some like SRAM.
