New frame from that Brant Bloke

by 25

Shedfire is pleased to release pictures of the first frame that’s been finished. 

The Ragley Ti hardtail has been fabricated by Lynskey Titanium in Chattanooga, USA.

Made from a variable wall thickness tubeset, the frame features an 

asymmetric chainstay assembly that we haven’t thought of a name for yet. 

Saying “it’s a bit of plate, with two cuts and two bends” doesn’t sound very 

good, but we’re pleased with the results. 

 

Cable guides are ‘bolt on, bolt off’, and fitted into the frame with alloy riv- 

nuts, which can be replaced if you’re heavy handed. We’re asking Lynne from 

Rothwells in Todmorden to find us the perfect P-clip and bolt combo. She will 

sort it. Geometry of the frame is best described as “Calderdale New School”, with a 

67.5deg head angle, 73.5deg seat angle, when the bike’s set up with 140mm 

forks.

There will also be a chromoly steel and “funky aluminium” version with the 

same geometry. The frame will be sold under a new brand name, which is being finalised right 

now (the details are with someone else’s lawyers).  Pricing for the ti frame will be “competitive” and should be announced in the 

next four weeks.

    Do one with a 25″ top tube & i’ll ‘ave one.

    On-ones were a little short for me.

    Looks like the chainstay bridge is in the process of showing the bird.

    I likes.

    Not convinced with the driveside chainstay setup, just doesn’t look right. It’s bound to work fine and will withstand chainsuck attacks fairly well

    Is the chainstay design related to the odd 3 fingered gesture on the shedfire site?

    Aye, what’s the BB height gonna be? Nice and low I hope.

    why does the frame feature an asymmetric chainstay thing?

    At a guess, the chainstay plate is to give greater combination of mud clearance and chainring clearance than can be achieved using tubes. Very much a case of function first.

    Big tyre wants the stay in one place, big chainwheel wants it in another. Sudden change harder to do with fancy metal? I’m hoping it’s tuned to c#.

    BB = 20mm below wheel centres at right height with 140’s Ben.

    So that’s 315mm or about 12.4in

    brant when will the steel and ally one’s be on sale?

    Steel and alloy mid/late May.

    Is it going to have a forward facing slot on the seat tube, the picture looks like it’s backwards which isn’t good for British mud. Also will it run full outers? As you are a uk designer it would be nice to have frames designed for the uk conditions.

    how much crap really enters the frame due to a rearward-facing seat tube?
    not a lot, surely.

    I’d wish that one of you UK designers would send the gear cables under the BB. My old steel Stumpy copes much better with Essex mud than my newer bikes.

    “Is it going to have a forward facing slot on the seat tube, the picture looks like it’s backwards which isn’t good for British mud.”

    Lynskey didn’t want to put it in the front due to the lack of material/space with the 31.6mm post we’re using (dropper post happy), and having thought about it (rather than just repeated what journalists write – and I’ve been guilty of writing things like that) I came to the conclusion that terrahawk did. Infact, more than that, I think the rearward slot is under compressive rather than tensile load, so I much prefer it. I might flip the slot to (both of) the sides yet though, like some of the carbon frames do.

    It will run full outers. They do work.

    “I’d wish that one of you UK designers would send the gear cables under the BB”

    we do with our Genesis bikes, i agree with you but i know some others don’t.

    Nice cs detail.

    Yes, water and crap can get in through a rear facing slot, certainly enough to cause seatposts to corrode in place with steel or alloy frames. A blob of bathroom sealant helps though.

    Or a little inner tube gaiter?

    Under the BB just gripes me from BITD “retro-mechs” with that big loop of cable. I’ll nod that modern Shimano/SRAM is a lot better and might work well.

    The other reason is that I hate cutting cables and trying to find ferrules.

    That chainstay is very similar to the Evil Sov’.

    Pretty and nicely thought out,
    What’s the biggest disk you could fit with that tidy disk brake placement?
    Also, any idea what the head angle would be with a 100mm? I’ve had enough of the head angle changing too much with a 5″ fork, gets a bit twitchy when pushing it, I prefer blurred vision to a face full of berm…

    “how much crap really enters the frame due to a rearward-facing seat tube?”

    Quite a lot.

    But do you have any evidence that that’s because the slot is at the back?
