38 chainring for truvativ firex

aya604

hi
have been let down bigtime by my lbs in parts orderfor my 2007 marin point reyes
i need to replace the middle chainring (38 ) of a truvativ firex chainset (28 38 48 )
also need a shimano cassette 12-25 and 9 speed shimano chain (or compatible)

Q1 - can anyone please tell me an online supplier of the chainrings I need?
Q2 - is there any cost/quality advantage from a different manufacturer (from
truvativ/shimano)?

many thanks
aya

Ebay and Google are your friends. Obviously capitals and punctuation aren't.

Whats with the smiley face numbers? I'm obviously out of the loop.

ps Truvativ is Sram not Shimano.

And in answer to Q2 - yes, do you want cheap, light or good? Pick two.

thank you for your reply

I tried google "38 chainring truvativ firex" and quite a lot of other similar things.
I am concerned I will get a chainring that will not fit.
I thought I may find someone who was not just going to tell me to google it.

your comments on puncuation and capitals are noted.

dont know why numbers come out as smiley - i am looking for a 38 chainring.
the triple is 28/38/48

cheers

i did know that truvativ was not shimano. the bike has shimano shifters and derailers though.
i dont know tbh what make the chain and cassette are (or the replacements need to be).

what I want is similar or better quality to what I have now but at the best value (chains & cassettes)

cheers

Sarky comments suspended.

As a rule more expensive = lighter, but may wear quicker. Sometimes more expensive = tougher but heavier. Sometimes very expensive = tough and light.
Cassette - any Shimano or Sram 9 speed will fit.
Hybrid cassette - no 15 (downhill) in link below about the closest but not cheap.

Yours is a hybrid chainset so mountain bike ones are generally smaller but hunt and you might find - I don't know

You need a PCD/BCD: 104 (large and middle) 64 (small ring).

Any 9 speed chain will fit. I use cheapest KMC available and change when stuffed. But others will swear by Sram or Simano - gold blingy ones normally.

sarky comments are no problem at all (so long as you are helping!)

thanks again
cheers

Shimano Deore chain rings will fit.

nicklouse

any 104BCD 4 bolt ring will fit or can be made to fit, the shoulders are differing diameters on either side and it changes with year and makers. so buy a file as well.

I recently bought a 36t 104BCD 4 bolt steel ring, shimano's cheapest for 10euros-7quid, I guess 38t were also available for the same price.
