I am pretty used to building bikes for me, which is to say big, burly, made for a man tank to go down things with some abandon.

However, I've never built a DH bike for a girl. I am assuming for a 145# girl that I want to go light.

I need some suggestions.

Its going to be a small Demo 7 frame.
That's as far as I've gotten.

Give me an idea of what you think a good build would be.
I am pretty sure I am going to do the pink King hubs on 823's, but that's as far as I have gotten.

Suggestions?

Already bought the frame. Never been a big transition fan, just one of my quirks.

She has a couple Specys, loves them, and as such I want her to have a Special-ed DH bike.

Not going to do anything from Hayes. Burned once too often by them. Thinking Saints or Gustavs (makes sense to keep some of our "easily burned" parts constant in case of mechanical issues.) and some sort of air fork for the front end.

823's are stupid heavy and light wheels are fundamental if you want a fun bike. I'm 70kg and I've been running 721's for years w/o problems. This year (or next at latest) I'm going to build my self a new set of DH wheels on EN521 with DT Revolution spokes and brass nipples. They're just as wide, welded, but 540gr instead of 590gr (823's are some 660gr?). :brows:

As you said that she's a XC rider she probably won't be hitting too many pedals, and therefore will be fine with XT cranks (they come in 165mm now!). I'm thinking of using them again (have Saints now).

As for a fork, dunno what A-C measurment they recomend, but maybe something like a 66 ATA or coil (personal preference)? The 55/Lyric/36 might be too small, while the Fox 40 comes in 6-8" adjustability (I belive). If you're buying a used fork, then a 06 Boxxer Ride will be fine as it's adjustable in 6-8". Totem coils should be fine, I think (I have a coil Pike which I like), but I've heard that Solo Air's are trouble.

Make the rest of the build light but with dual ply tyres.

Is there a way to run a 40 or an 888 light? I thought someone was doing an air version of one of them.

a 40 would be fine. i weigh less and am using one just fine. i am using a soft spring, its a bit too soft for me, and you can go even lighter too, there is xtra soft.

you could look into using crossmax sx wheels, those are nice!! otherwise maybe use 819 rims. 823's are kinda overkil

I have the 823's, love them.
But I am 230lbs of pure man jello.

I think I have it somewhat figured out like this:
Marzocchi 888 ATA
Hone Cranks
Magura Gustav Stoppers
E13 chain guide
Easton Monkeylite DH Riser Bar
Thompson post
X9 shifters/derailure
PG-970 DH Cassette
PC-991 CrossStep Chain
King hubs (20mm front, fun bolt rear, 28 holes) in pink 'cause she's a girl.
Pink ODI grips

If she is light I'd rather go for her with a strong SC fork. Totem coil or 66 SL ATA.

Gustav's will be overkill. I'm very light and when switched to lighter breaks I only feel a sligthly larger arm pump but not much loss in breaking power. Would rather aim at magura luise. All my friends who race them are supper happy with them.

Switch the PG-dh casette as it is heavy for some road one(sram makes quite good road casettes).

ex823 may be nice but if she knows gow to ride light I'd try 721s.

Shimano Ultegra and DA cassettes have the nice one piece carrier that keeps the cogs from digging into aluminum driveshells (It actually is kind of a big deal, especially on King hubs). Plus, the cogs aren't that strong, especially when you consider the cassette weighs twice the DA. Strong roadies put more power through their bikes than the biggest of us do.

Gustavs are heavy and parts are hard to find and expensive. Nobody needs brakes that strong, especially not someone really light. Shimanos or Juicys would be perfect.

I am 240ish and 721s are fine for me. I can get away with even running 819s with a good wheelbuild. Cut the rims down to 721s max, maybe even 5.1s or 719/819s, and there is no reason to go 28 holes. It's not much lighter, it just ****s you on rim compatibility.

Marzocchi forks are heavy and the damping is too heavy for lighter people to get a consistent, quick and responsive feel. Even at my weight, it was difficult to get my 888 damped light enough in regards to the high speed compression and rebound to feel like a proper DH fork. A Totem, Boxxer or 40 would be lighter weight and have better damping that wouldn't kill her hands at Whistler, while probably costing less money.

I hate Kenda tires. I think they're awful, but every girl I know that is into DH riding loves the Nevegal. I think it's because they do not break loose in turns all that easy and they have good braking traction. On the plus side, they're cheap and the 2.35 comes in at a good size.

I hear you about Marzocchi. I have always ridden 888's for DH, but I am a tank on a mission to make dirty, dirty love with a tree or two.

I think a 40 if I can find one cheap is the ticket.

We're both HUGE fans of going tubeless. Which of the Mavic line up is the right one for that?

I like the idea of the gustavs just because that is what I run, and I have 0 complaints about them.

However, after going for some demo rides today, doing SRAM for her isn't going to work. She's so used to Shimano's action that I think it would be too hard to break her of it.

Looks like my princess is getting XTR for a der, XT for a rear shift, and a Sram chain because I love the link.

I guess we could always slap Saint stoppers on her's, I have more then enough of those on bikes...

She rode the Maxxis 2.35 Minions today, loved them. I see a 2.5 UST up front, and the High Roller 2.35 in the back.

a lot of this really depends on how 'hard' she is going to be on stuff. My guess is with her weight she can get away with a fair bit of stuff that may seem WAY underbuilt to you...

For tubeless you have 823 or 819. 819s are an 'enduro' rim and the 823 is the heaviest rim mavic makes (certainly something she does not need).

saint/xt brakes are good and light and plenty of power. I would bet 819s and DB spokes with a DH tire run tubeless would be more than enough for a wheel set for her (2.35 F/R or 2.5/2.35). Drivetrain is a personal thing, (I like shimano cassettes better, but sram shifters/der) just get a 'better' cassette, the weight diff is large. Some 'all mt' cranks like XT or gravity light...what ever pedals she likes....

Bars and stem are a bit personal as to width/sweep/length....but again, 'AM' or 'enduro' parts will be strong enough for her and save more weight....same with seat/post.

You should be able to get under 40# without doing anything outlandish or spending lots of $$.

I really think a Totem Solo Air would be great for her up front. The Solo air hasn't had too much in the way of problems, its the 2-Step that has all the problems and probably why most people say bad thinks about the Totems. They did have some real issues with seals leaking, but supposedly that has been fixed so don't buy an old fork, get a new one. I personally haven't ridden a Totem but I have the Lyrik solo air and the fork has been great so far with no problems at all, set the air pressure, adjust the H/L compression and you're good to go. Just remember Rock Shox has the air spring pretty dialed compared to anybody else.

Yep, Ultegra will be just fine. With a 12-27 cassete she will also have ample range with a 32-34ish sprocket, and thus saving weight with a smaller chainguide as well.

If you already have Saints I would use them over the Gustavs, they're strong enough and lighter.

I'm sure it will only take a few days to get used to SRAM, otherwise make sure she can thumbshift the Shimano and brake at the same time (not a nessesity but it's racy ;) ).

If you're going UST, I'd go with the 819 rim over the 823 for her. I ridden simmilar weght 719's a lot and they took my abuse w/o problems. Only one fail (rear) and that was because of untrued spokes while wallriding. Good ****!

I've used the 2,5" DHF/2,35" HighRoller combo my self and the HR tended to slide out whe I was really pushing it in corners. Side knobs are better on the DHF but they didn't sell it in Sweden in 2,35. Maybe she won't push it that far and will be just fine with a HR?

Maybe I'm lazy, but I tried to "standardize" parts between my wife's bikes and mine - just for the sake of not getting different bleed kits, etc. It hasn't totally worked, but I have gotten her non-road bikes to align so it makes it easier if I have to cannibalize to make one bike work! (ie, both her dh and xc run hayes, shimano, etc.)

My wife isn't much heavier than yours, and I would stay away form a rear air shock. I personally don't find them as supple on small chattery stuff. She has a small VP Free with a DHX set up with a lighter spring, and she loves how it rides (for point of reference, she mostly shale surfs at Plattekill).

Good luck!

I have been thinking about this more and more, and I must agree with others, I think a Long travel single crown is in order for this bike, like a totem OSlo, 66SLETC. I would personally keep her on the shimano shifters, the 2:1 shift ration is easier on the thumbs, it has a lighter push than Sram does. good news is you can get the newer shimano stuff which is thumb thumb, and the position os more fine tunable to the rider!!

Well the VPP designs simply kill air shocks but if you mount it on a frame with better characteristics it may work nice with air. Yet I'd go evolver or AVA moded dhx air instead of rocco air. It has to many issues and all I've tried felt like crap (but it might been because of dumb owners)

WBC nailed it every sense. If you want tubeless 819. Im 190 and have beatin a set of 719 on my trailbike (same as 819 but with tubes) and no issues. Funny about Kendas, My wife loves them for just the reasons stated.
Go XC bars, I have seen 240lbs guys ride hard XC on carbon and hold up. Her 140lb frame will be fine. It just depends how much $ you want to throw at it. I went cheap until I knew she dug it and now its going to cost me:)

I'm 6'7" and 275...and my front Gustav is almost too powerful for me...Go with the Louise FR's (Or maybe just the Louise). I've set my FR/XC bike up with the Louise FR's (F-8" R-7") and have the 8" version on the rear of my DH bike. It's all the brake she'll need. Pad life is pretty good even for a dragger like me...

OMG, mr Squirrel you're a bigfoot! :shocked:

If you get an amunition belt hanging from one of your shoulders I bet you'd look like Chewbaka.
I was up to just under 300...but it finally got light out at 6:30am so I can commute both ways now...I'm down 25 over 2 months...hopefully it'll keep dropping...

Oddly enough, I was just thinking about grabbing a bandolier from a surplus store and modding it to hold 22's of all the different microbrews I can find around here...that would be killer on a hot summer day...except I'd need to drink them all before they got warm...that could spell the death of teh squirrel...

I am still voting for Strokers for the brakes, kightweight, decent price, Great Modulation. Lots of power, but lots of control over that power. Not to mention the pretty white color!!!

Hayes + the dirt family = teh suck.

I've tried them many times, and every time I've gotten burnt.

I am going with the Saints, they're cheap, easy to work on, and are on all of my bikes sans my DH bike.

For some reason I just like DC for DH. Less fork whip I think is the reason. I would do a 66, but that's more then I want to spend. I think I can find a moderately used 40 or RS Boxxer for what I am willing to spend.

Also remember, I doubt this will ever be a race bike. She likes racing Super D, but beyond that the whole hard core thing is sort of lost on her.

And we got her orders today, looks like she is going to be missing a couple summers. Thanks big gray weenie!

I would vote for the Saints. I am female I'm only just starting to have a go at DH, and well my '07 XT brakes handled it fine with 6" rotors, and being my first time they were 'on' most of the way down!

Obviously the biggest priority apart from brakes is a fork that will suit her weight, Boxxer is supposed to be the best DH fork, but I would consider single crown offerings for sure.

As for the rest, it's really down to personal preference and a balance of budget / weight / durability.
