This is an older thread I found while doing a search...

So from what I have gathered, unless I have a Chris King headset (which I don't, I always run Cane Creeks :thumbsup: ) I can't just buy a new crown race?

I don't want to have to buy a new lower when I could just buy a new race (I assume the cost is more for the lower cup).

I have posted about this and place the blame mostly on the fork builders.

Why the fork builders?
If a bike builder knows what fork will be used, they can adjust can't they?

My sweet Vulture Wade built clears a Reba just fine...and that frame was built almost 3 years ago...before the Reba existed.

I'm just glad the Reba has external adjustments...rather than having to dig inside your fork to adjust the rebound...

I think it's hilarious that of the three things that make a 29er unique, somehow one of those factors - the fork dimensions - appear to have been 'forgotten' by many bike companies.

I mean if it was a weird fork you'd understand, but the most popular and most prevalent fork on the market? AND the tech drawings are right there on the RS website for all to download!

I hate to flog a dead horse, but in any other professional industry, people would've been fired over this joke, but in typical bike industry fashion, shoulders were shrugged by both consumers and companies alike and a 'new' product created to fix the 'problem'.

Small frame folks have this issue too...check the surly forum and the folks with the 1x1's are having the same probs

Since when has Surly been 'small'? Small to me is less than 300 frames a year. QBP would do that every month within the US alone, AND they only have 4-5 designs to perfect. For us custom guys every single frame is a new frame, so even guys doing 50 custom frames a year do ten times more new designs than the mass merchants AND have to do literally everything themselves and still manage to get it right more often.

My bad, I wasn't very clear lol...I meant frames for vertically challenged folks. Small frames. the downtube thing also manifests itself as toe overlap on smaller sized frames.

Reba

I have contact on the Reba floodgate adjuster even after getting the S-3+5. My vulture has a super awesome big-ass down tube. Anyone have a link to a precedure for removing the adjuster and leaving it off?

How easy would it be for the fork manufacturers to fix this? There IS a lot going on in there. Shouldn't there be a standard clearance that everyone can build to w/o knowing the specific fork?

I have taken King crown races and on a bench grinder machined away the lip and then touched up with a flat file
yields a 3mm spacer
done it probably 30 times...
never an issue

 

[beerorkid]

I just got a mooto-x ybb 18 inch and it is running the 07 reba sl.
the cap on the lockout switchy thing just kisses the downtube. it would be enough to scratch it, possibly gouge.
I had read this thread a while back and was worried about the new ride.
Kinda bummed, gonna get a spacer.

 

[aes]

try a Willits

Wes bends the downtubes to allow for clearance on any fork. The frame in this picture is very small (rider is 5'3") and has plenty of room underneath.

 

[None]

It is quite strange that both my Fishers, RIG and Paragon clear the pop-lock with all kinds of room and does so on all size frames. Yet many the high dollar custom builts of all sorts connot get this right.
How can this be Rock shox fault??!!
Here I now see that the vaulted Maverick has the same issues. Dam Maverick!
For crying out loud...a simple solution for all you custom frame builders out there, BUY a dam fork and make sure it fits!
Yer slide rule is broke! Design for what the market has provided!

I guess if a builder made the headtube an inch and quater (oh wait they did that did'nt they) we woulld still by spacers to fix the stupid FRAME BUILDERS problem and blame the dang headset manufacturers!!??

 

[unsub1]

Keep in mind that some of these builders were building frames a LONG time before there was a Reba. The first 29er White Brothers didn't have this problem. I can't imagine that when Rock Shox finally give us more options that they'll stay with the current design, which was obviously just a tweaked 26" fork.

FWIW, this is actually a problem on some 26-inch frames as well [this coming from my conversation with a well known shop in PA]. HT's with long travel forks maybe. Like other things in the industry, it points to a need for some level of standardization for what is spec'ed. When I bought my Dean, Reba's were just starting to hit the market. Can't blame Dean because they didn't have an advance from RS. My Niner clears a Reba with no problem - Dean-o doesn't. Dean-o will clear a White though, which was the standard when I bought it.

Exactly, but why are BRAND new Deans and Moots having clearance problems when Rock Shox supplies a frame manufacturers area on thier site with details for them!!??

But really, If your building a 29er these days you really have only a few fork choices so how do they screw it up is beyond me...the specs are there for the taking. If something new were to come out that would be another thing.

It just kills me to see a Moots with a headset spacer taped on to clear the most common fork out there! AND one built tomorrow will need the same spacer!!
I could understand if this was a new fork and you had all your bikes built in China and had already taken delivery of your new years supply of 10k bikes, but these are small individually built bikes! You could order your dream Moots or wait longer for your dream Dean and it still won't clear a Reba. WTF!!

 

[Thylacine]

Because they're lazy and not as hungry for your hard earned dollar as the smaller guys is one possible answer.

 

[dRjOn]

does this maybe have something to do with leaving the lower section of the head tube unsupported? with supension forks getting more travel and longer for 29"ers (and the stanchions being big and crowns wider), the down is at a steeper angle. if yer frame isnt longity long in the top tube/front center, this will lead to clearance issues unless: the down tube is bent, or it is gussetted, or it, and the head tube, are super thick in order to combat the pressures in the area. for ti frames this is more of an issue in terms of fittings and shaping and what not i would imagine. there are lots of 'morphing options' for aluminium, steel tubes are thinner-all reducing the problems...but not erradicating them.

i agree that (especially) expensive custom bikes, where the fork is either unknown or known to be a clearance issue should have this discussed with the person ordering the frame. i notice seven and IF have gone to gussets( presumably due to raised down tube a smidge?!) to aid clearance...
