I’ve bought a dh frame! Now help me spec it please…
I’d imagine the 36’s will be too short and they’ll make the h.a steeper than it should be by a few degrees. Coming off the reign you might not notice but I’d say the BigHit is supposed to be a few degrees slacker at least. On a budget RS Domains would work well there or Travis 180’s.
Leave the cranks as they are, xc cranks will be fine unless you find yourself getting into it more. Chainguide wise I’d go for an E13 Lg with taco.Posted 8 years ago
They spec the juicy 3s on some of the complete DH bikes I was looking at, so I guess they’ll do – I probably won’t be going at light speed anyway!
The guy in the shop thought the 36s would be a good match with the frame in shorter travel mode (it has adjustable geometry apparently).
Was thinking Domain if I saw a cheap 180mm one – or start with the 36 and if I get into it, maybe the new Boxxer when it comes out.Posted 8 years agodavidtaylforthMember
All those parts will be fine, the only things I would change would be the forks for some dual crowns to slack the head angle out a bit, and probably the rear wheel for something a bit stronger.
The 719/819 should be able to cope but if your not too smooth and just want to have a go at battering your way through stuff then I would look to get something stronger on the back, save the light wheels for the reign.
Juicy 3’s will be fine with some big discs.Posted 8 years agoMr AgreeableSubscriber
That sounds like a lot of fun, and will make for quite a light build.
You’ll need to cut down the seatpost as it has an interrupted tube design, so get a cheap one.
Chain guides: get a single ring specific one with top and bottom rollers. Be aware that there are some fitting issues with specific guides and frames – maybe have a look at the one that Spesh specced on complete bikes?
Forks: you might find the BB a bit low with those, some 7″ ones will suit it better.
Over time I’d change the cranks for something a bit beefier, and fit a 36T ring. They should be fine for dabbling though.Posted 8 years ago
If you’re running the Bighit in shorter travel mode with 160mm forks is it really going to be much different from the reign with 160mm forks? If you can get your hands on some 2006 or 2007 888s then it would really sort the bike out and allow you to plow through the rough stuff.
I had one of those, and I agree the fork is too short.
I had a 66sl (170mm) on mine but a 888 200mm woud be spot on.
An early 66 with a tall crown may also be OK. 170mm but axle to crown is quite large on the earlier ones. 580mm ish IIRC.
05 66’s (170mm) versions come up just short of the 888s in axle to crown height.Posted 8 years agoDM52Member
The Highroller 3C’s I am sure are ace however you could run with the cheaper Slow Reezay front and Super Tacky rear highrollers if you wish to save a few bob.
If you haven’t already perhaps a set of 5.10’s, body armour (shin and knee pads as a bare minimum), full face lid and goggles / glasses.Posted 8 years ago
Already got the tyres, certainly wouldn’t have paid retail but got a good deal off the classifieds here.
Also already have full face, armour, pads and plan to buy five tens next weekend.
Anyone recommend some good, reasonably priced shorts with hip protection?
Gnargnar – It won’t be different in travel to Reign, but I’m assuming it’ll be a lot slacker and with a more rearward weight bias.
But if the fork feels wrong straight away (or I spot a bargain or get a swap for my Rev in the meantime) – I’ll get a longer fork.
Already leaning toward the new Boxxer – but even the Race model is a lot to spend before I’ve really tried DH properly (and also not actually on sale yet).Posted 8 years ago
You must have moved on from that hospital visit after Mabie…..
Well, I wear knee pads now – can’t vouch for my riding skills. I should build this bike up and ride it round Mabie just to be on the safe side.
A couple of us are up in the western Stanes the week of April 20, if you fancy some midweek riding? Staying next to Kirroughtree 🙂Posted 8 years ago
I’ve done something a bit rash. I’ve gone and bought myself a Specialized Big Hit frame with the intention of trying out DH on the cheap.
Couldn’t resist it at £350 new with a DHX 3 coil, a pretty good price even though it’s small and the ’07 model.
Initially the spec will be as follows, welcome comments or suggestions…
Fork: Fox 36 Talas (borrowed from my Reign)
Wheels: Hope Pro 2/819 front wheel, XT/719 rear (also borrowed from Reign)
Brakes: Juicy 3
Cranks: Evolve XC with bash, single 32t ring (or buy something sturdier?)
Headset: I’m thinking Pig DH pro, been impressed with these before.
BB: Shimano Deore level probably
Seatpost: Giant A5 off my Trance
Stem: Holzfeller 40mm
Bars: EA50 685mm low rise
Pedals: Wellgo flats
Tyres: High Roller 2.5 dual ply 3C
Saddle: WTB Rocket V
Chain device: Your suggestions please
Anything in there wildly inappropriate and likely to lead to injury or death?Posted 8 years ago
I’m sure the new Boxxer will be a great fork eventually but I’d avoid the first generation as there could well be teething trouble with it. It’s also pretty expensive. You should be able to pick up some 06 888s for around £200, they are bombproof forks, very plush, very stiff. Very simple, very reliable. I wouldnt waste my money on something if I wasnt sure I liked it.
Alternatively you could always try a totem with a spacer on the crown to give it some more height.
Actually what am I saying….sure get the new Boxxer WC, if you dont like it then there’s a chance it’ll surface on the classifieds for me to nab.Posted 8 years ago
OK, frame’s arrived (as seen on man bike thread), and the spec has changed a bit – see below.
I have a few more specific questions though:
1. Do I need DH tubes?
2. Should I go for 203mm discs? Juicies should work with any rotors shouldn’t they?
3. Is BB quality important? £35 Deore or £70 Hope (which would probably move to my Trance later)?
