Bike issue

Nevakonaza · 2 Sep 2015 at 13:20

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?

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.

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

Do you use flat peddles or some kind of clipless?

Flat

Nevakonaza · 6 Sep 2015 at 10:13

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.

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.

Whys that then?..is SRAM good make too or should i stick with Shimano?

appreciate the replies

What about the chain ring,I see my bike has 3x chain rings near the pedals,Might as well replace those if im going to the trouble of replacing the cassette,chain etc..then its all new.

Or at least replace the one the chains on the most,which is the middle one..infact i never use that gear so its always stuck on the middle ring,The only gears i change are the one on the cassette.

Just had a close inspection of my Cassette and there is indeed a broken tooth on it..The smallest ring.

Just had a close look at the chainring too,im no pro but it looks okay to me,plenty of teeth lenth on it it doesnt look all that ware to be honest,like i said though this never gets moved anyway...the whole bike is a mess though its got sludge buildup all over the moving parts and its dried..really needs a good cleaning off with degreased and pressure washing i think.
