2 bikes into 1
I have a standard Trek 1400 2007 model and also a Giant OCR2 2006 model. I am trying to keep 1 and sell the other. The Giant has Mavic Cosmic elite wheels and also Ultegra 9 speed groupset. The Trek has 10 speed 105 groupset.. How can I mix and match to get the best bike and sell the least best.

PPersonally - all other things being equal, I'd hang onto the ultegra bike and sell the other.
But depends on which bike you prefer.0 -
Sell both and buy a new.
Then you get exactly what you want.0 -
your nine-speed wheels will also take a 10speed cassette with a small spacer avaialble from most bike shops. 10-speed cassettes are actually narrower than 8/9's so 10 speed casettes fit on all 9speed wheels, but not the other way around as some 10-speed specific wheels are too narrow a freehub body.
so you could take the wheels off the giant, put the 10-sp cassette on it and keep the 10s 105 which is what I would do..0 -
That's a complete load of tosh. 9 and 10 speed freehub bodies are exactly the same width (in fact 8 is the same too). 10-speed cassettes are also wider than 9, not narrower, as they have a special last cog and spacer (or carrier with multiple cogs) where the last cog is dished slightly, so it fits slightly further towards the middle of the wheel than the last cog on 9-speed - the part which fits on the splines is obviously the same width (no spacer required for either). Hence some wheels have a problem with 10-speed but not 9, since the rear mech has to go a little bit further in towards the spokes and can interfere with them.gkerr4 wrote:your nine-speed wheels will also take a 10speed cassette with a small spacer avaialble from most bike shops. 10-speed cassettes are actually narrower than 8/9's so 10 speed casettes fit on all 9speed wheels, but not the other way around as some 10-speed specific wheels are too narrow a freehub body.0 -

sorry - but thats not what I have been led to believe - I thought that the 10speed are narrower - hence why you need the spacer to put a 10 speed casette on an 8/9speed wheel.
but - thanks for declaring it a "complete load of tosh".. ..0 -
Led to believe by who? Have you actually put a 10-speed cassette on a wheel - from what you say it is just hearsay? Given the last sprocket on 10-speed is dished so it sits slightly further towards the spokes than it would normally, using a spacer behind the cassette would be nonsensical. http://sheldonbrown.com/harris/k7.html#10cassettesgkerr4 wrote:sorry - but thats not what I have been led to believe - I thought that the 10speed are narrower - hence why you need the spacer to put a 10 speed casette on an 8/9speed wheel.

I can only assume you are getting confused by the need for a spacer on Mavic wheels (for both 9 and 10 speed), due to the cassette body on those being made wide enough to fit a Campag width cassette on.
I stand by my "tosh" comment - do you have a problem with misinformation being described as such?0 -
I do - shimano 10 speed cassettes come with a thin spacer for a reason.
http://cycle.shimano-eu.com/publish/con ... sette.html
basically MOST hubs are 8/9/10 speed compatible and require the spacer that comes with the cassette. The exception is shimano made a few 10 speed only hubs (I believe dura ace and ultegra wheels from 2006/2007 and the dura ace hub too - although the 2008 DA hub is 8 and 9 speed compatible.)
On a mavic hub you need to use both the mavic spacer and the shimano one if you have a 10 speed cassette. The mavic spacer is needed because mavic make a campag compatable cassette (http://www.mavic.com/road/products/M10- ... x#moreinfo) that goes on the mavic M10 freehub - campag is wider than shimano so the mavic spacer is needed for shimano cassettes.
8 and 9 speed shimnao cassettes have the same width as each other.
10 speed cassettes are narrower at the freehub - but the large cog spider is dished (probably to make a less dished wheel but constraints of standardisation seem to have made this redundent now.)
Hope that clears it up.0 -
thank you alan!
I don't think I was guilty of "misinformation" - I could have been mistaken, but misinformation sounds as though I was deliberatly trying to mislead the OP - which I wasn't!
I was "led to believe" by other forumers - not on this right enough (I searched) it must have been a thread on the old cycling+ forum. very early in the year I bought some new wheels for my trek - I was trying to decide between the Shimano R561's and the R5600's - asking for advice on the C+ forum It was pointed out that I didn't have the option as the 5600's were 10-speed only ( I have 9sp tiagra) - how can this be I asked, only to be told that 10-sp cassettes are actually narrower than 9's..0 -
Which bike has the better frame? the Trek 1400 Alpha SLR or the Giant OCR2?0
-
Well, the OCR2 is a Giant after all!!0
-
pretty simlar probably - both 100% alloy aren't they? - I mean, no carbon stays or anything.
keep the one that fits you best / that you like the look of best!
That said, the 1400 will have mudguard eyelets does it? - in which case it might be a better bet as an 'only' bike.0 -
Didn't accuse you of deliberately misleading, just of repeating misinformation (which is defined in my dictionary as false information - no malice implied). Indeed I am guilty of the same thing myself with the suggestion that there is no spacer with a 10-speed cassette - I was wrong!
Anyway, you were yourself misinformed, as a 5600 wheel will work just fine with a 9-speed cassette, as is clear from the product page. This is because 8/9/10 speed freehub bodies are all the same width. There are Shimano wheelsets which only work with 10-speed, Ultegra and older DA with alu freehub bodies (newer DA wheels have a ti body which will take 9-speed), but this is because the splines are taller, so that a 9-speed cassette won't go on at all, nothing to do with the width. I presume the OP doesn't have either of these on his 105 equipped Trek!0 -
The trek does not have eyelets for mudguards. I would have thought the trek has the better frame as it cose a fair bit more than the giant.0
-
in all honesty both those frames are pretty mediocre ... very middle of the road alu frames.
i'd sell both and buy a planet x carbon ultegra £999 deal, or a focus cayon on discount or whatever.
there is such a thing as good alu for sure, but neither of those frames are it.
sorry if this is unwelcome news.0
