help with trek xo upgrade!(14 posts)

help with trek xo upgrade!reklar

Hey now,

I've been lurking awhile. I'm a newbie to road and cross, but have been riding MTB for awhile.

Just picked up a Trek XO and would like some advice on what to upgrade in order to save some weight and just to improve the bike's performance...I don't have deep pockets so I'd like to maximize the weight loss per dollar (I know I could shed a few pounds myself, but that'd be too hard! ;)).

Anyway, here's what's on it:

2000 Trek XO
Shfters/Levers: RSX STI
Rear Derailleur: RSX
Cranks: RX100
Front Derailleur: Nexave
Brakes: STX cantis
Rims: Sun ME144
Hubs: Unknown! The only mark on them seems to be a Z or N..any ideas?
Tires: IRC Cross Country 35C
Pedals: Bontrager RE-1 (similar to shimano SPD)
Stem: Icon -Graphic Series
Bars: Icon

I've got a decent saddle and post, so those aren't negotiable. There's a chance I may race a bit, but the primary use for it will be to ride a lot of road (including lunchtime group rides w/ roadies) and occasionally ride fire roads in norcal.

Anyway, I'm psyched to have a cross bike!
Any advice will be appreciated!

The most noticeable upgrade would be lighter wheels. This is because wheels are rotational weight as opposed to static weight. Different wheels will have a more immediate effect on the way the bike rides. The cheepest way to lighten your wheels is to get some light road tires. Since you are planning to do mostly road riding in the near future, you don't need the beefier (and therefore heavier)'cross tires.

Congrats on your new bike. I think you will find that if (heaven forbid) you could only have one bike, a cross bike would be the one to choose.

The stock XO is a great bike.
If you do race CX, after the wheels, the cantis are next in line for upgrade - Frog Legs best for muddy conditions.
I would wait until you break the rear mech and shifters before upgrading to 105 or Ultegra, and upgrade the crankset as it wears out.

Have fun.

And it rocks! THE BEST BIKE IN MY PITIFULLY SMALL STABLE. But if you feel the need to upgrade it (as I am slowly doing), I would recommend this (hope it helps):

Shfters/Levers: RSX STI - replace them when you crash and break them
Rear Derailleur: RSX - ditto
Cranks: RX100 - (I have a Tiagra crank, but I'm sure this is fine for now, are they cross specific rings?)
Front Derailleur: Nexave - replace when crash
Brakes: STX cantis - stopping power seems good to be, but definitely could be lighter and slicker, check eBay for some XT's or froglegs or paul's
Rims: Sun ME144 - My bike came with Rolfs, hmmm... Definitely look for a cheap good pair of wheels in the classifieds of RBR or eBay, I suggest the Bontrager Race Lites
Hubs: Unknown! The only mark on them seems to be a Z or N..any ideas? - Ditto
Tires: IRC Cross Country 35C - Work great!
Pedals: Bontrager RE-1 (similar to shimano SPD) - Good pedals. I switched to Eggbeaters.
Stem: Icon -Graphic Series
Bars: Icon

*I would also recommend top mount levers. It may add some weight, but the control is well worth it.

I swapped out:
- the saddle and post (Selle San Marco Concor Light Ti and American Classic post)
- aluminum fork to steel Sycip fork (for comfort)
- new headset for threadless steerer (probably something decent but under $30)
- stem (this is next, probably a ritchey pro)

may be a little flimsy for offroad usage. Get some Velocity Aerohead/ Ultegras!

You think so???

I thought I saw somewhere that Keith Bontrager was racing and trail riding on them in CA...
re: race litesatpjunkie

Keith is an excellent cyclist, about 140 lbs wet and gets them for free. If you match this profile go right ahead.
Mavic Classic SCC's!!!!!atpjunkie

Nashbar has them for 449 a set!!!! either tubular (Shimano/Campy) or clincher (Shimano) this is the wheelset you want. It's Mavics Paris Roubaix wheel. Strong light, Ceramic surface for wet braking and stealth BLACK. this is the BUY

Touche.

Sadly. I'm like 200 lbs wet. But have had good luck with their mountain bike products...

My rolf wheels work great though.

I'm a Clyde as well. Rolfs should be fine as long as you shy from the Sestierres and Pros. I like the Velocity Rims (Aerohead and deep Vee)

So I've been able to go on a few rides on the road...

My gearing seems a bit high even on the road for me...
The rings are 50-39t up front and a 12-26 rear cassette.

I'm *reasonably* fit, but we have some long road (and MTB!)
climbs here in norcal, and I think I should be able to spin
up those hills. Instead I am grinding away--I guess I'm really
used to having a granny and spinning from my MTB riding.
Any suggestions?

Would going to a MTB derailleur with a 12-30 or 12-32
cassette fix my problems? Will the STIs work with that
type of derailleur?

How much efficiency can be gained my switching out my 35c
cross tires to 23c slicks?

Thanks!

Definitely, your gearing is set up like a road bike (at least the front 50/39). The back (12/26) should be fine for most applications.

Most people run a 48/38 or 46/38 or 48/39 or 46/39, depending on what you're looking for, or some people go with a single ring up front. But it sounds like you're looking for versatility. I use my bike a lot off road and usually shoulder it (good practice) on the really hilly sections that I would normally granny gear on my MTB.

Are you planning on taking your cross bike offroad at all? It's a lot of fun and really improves your handling compared to a MTB.

Some people run the granny gear so that they can still have the 50 for the road.

Slicks will definitely help on the road.

Oh yes, STI and MTB derailleurs work.

get an MTB rear der. and cassette. go 48/36 front and 11-32 rear. you'll be fine except for some chain slap.

Thanks for all of the responses.

I'm probably going to go with a MTB derailleur and cassette so I can spin up some of the hills around here. I think my rims are in good shape and of good quality--the hubs could be replaced but until they break down I'm going to stick with them too. I may get a new set of wheels strictly for road riding however....

Other than that I'm going to leave it stock and get into a bit better sape before replacing components...I may replace the brakes and add some Frogglegs for technical descents...we'll see how much I can get onto the trail this summer! (MTB riding takes up most of my summer riding on the weekends--road during the week. I have a feeling winter time will be for cross!)

Thanks again!
