I seem to have a shed with a nice bike I bought the missus, but no bike for me, yet 6 wheels, 2 disc brakes, stems, gear sets etc, cluttering what could be a bike.
So after opting to ride the South downs again (first done when I was 12) this year, and I'm taking the missus along for the ride, I thought that I better get a bike to ride it on!

My last few bikes have been a XC bike that I slowly turned into a jump bike. I then swapped the frame to a Identiti Dr. Jekyll.
I started to tire of that aspect of biking and went down the full sus route ending up with a bike I hoped could do some XC and a bike of downhill. A freeride bike if you will and that was my Cove G-Spot.







A couple of years ago I moved out an hadn't really touched the bike for a good while. This, paired with needing the money, I took it apart and flogged most of it on ebay.

I've opted to back down the XC route after a long time away. So I've bought the first component! A frame!





That is my unstickered (it was cheaper!) On-One Whippet. It's my first carbon fibre frame, so I'll find out what it's all about when I muster the money to complete the build. Preferable before the South Downs!

Has anyone got one? It's a bit of a gamble as I've never seen a complete one in the carbon and never ridden one so I'll hopefully make it all fit me nicely when I come to pick/ fit the stem/ bars/ seat/ seat post.
It was a choice between red, black or yellow. I somehow ordered the yellow one. Hopefully it'll look quite good as opposed to my past history of black bikes.

I'll be honest, I'm not quite sure on the finished spec yet, so any comments are happily accepted.
I had planned to use my 9 speed XT groupset that I have kicking about, but this frame needs a direct mount front derailleur to start. 10 speed seems to be the way forward these days. I'm thinking 2 cogs up front and 10 at the back. So this would require all new things.

I'll see how it turns out...

Very nice. Not got a whippet, but have heard good things about them though.
However, I do have the 456 carbon, and I bought a yellow one too. Never seen another one (in yellow) either:

Looking nice. Does yours have a push fit BB? That's also a new one on me since my time away.

Nope, the 456 carbon has threaded bottom backet inserts but is a 73mm shell width, not 68 which is more usual.

Right I've got a headset, grips and bottom bracket. I have a current thread running on 'which fork'?

But back to the rest, I'm having a bit of a hard time choosing 10 speed vs. 9.

I have a lot of 9 speed XT gubbins in the shed from my previous bike. I'd need a direct fit front derailleur if I go 10 or 9 speed, so this I have to buy either way. Other than that it would probably work out slightly cheaper being able to use existing stock.

It seems that if I go brand new, there isn't much difference in the cost of XT 9 vs. XT 10 speed equipment.

I quite liked the idea of running 2 cogs at the front and 10 at the back.

A silly question I'm sure, but how much difference is there between a 9 speed and 10 speed front derailleur? If I set it up to run 2 cogs at the front only, would it really matter? Could I use my current XT 3 cog/ 9 speed front derailleur shifter with the front derailleur if I decide to go 10 speed at the back?

I might have a deadline to build the bike 8th/ 9th/ 10th June. So, basicly a month, I better get a move on!

My advice would be:

  • Go 1x9 speed and you save the cost of a front mech, and shifter, and stick with the 9 speed stuff. You can tackle most stuff as well. I'm a heavy rider and I cope fine.
  • Forks - Rebas. Check out the usual suspects and you'll pick up a set of just over two hundred quid (On-One site or Planet X)
  • Brakes and wheels. Merlin often do a package deal for two wheels, SLX callipers and levers for 250 quid.
  • If you have brakes but no wheels, try Superstar components for one of their wheel sets. The wheels are superb value, although customer service is a bit poor.
  • Tyres - Conti Race day compound tyres. Pick the tread that suits your riding style. Bike-Discount.de is the cheapest I've found and they do a 2 tyre + 2 tubes offer that saves you even more money. These tyres are very very light yet offer good traction, wear rate, and don't pitch-flat much if you run them with reasonable pressure in them.

Thinking 1 cog at the front would limit me for hills or downhill straights. Always used two of my 3 cog setup. Never used the little cog, but can't see an advantage to just 1?

Cogs - Not sure on the 1 cog at the front approach. I'm thinking that it would limit me for hills or downhill straights. Always used two of my 3 cog setup. Never used the little cog, but can't see an advantage to just 1 when I'll be riding mixed terrain.

Forks - Reba's seem to have a good following, so it's probably the path I'll go down.

Brakes and Wheels - I have a selection of 6 wheels that I can hopefully pull something out the bag from. I've got a few Hop disc brakes kicking about.

Tyres - think I've still got a set, if not, I'll come to these when I get there. I'll look into the Conti's.



I do some cranks though. I'm used to ISIS mounts - BB and cranks. All seems to have gone down the hollewtech route these days. How's it work now then?

Similar to a BMX 3 piece crank set?

1x9 will give you about 20mph on the flat spinning quite hard with a 32 front, so yes it does limit top speed. Hills I've never had a problem with - even the steepest of stuff - and I'm 18 stone and 6'5" so hardly a mountain goat. That said they're not for everyone but that set-up will save you a few quid for a front mech, hence the suggestion.

External BBs simply screw into the BB shell of the frame. Bigger contact area and bigger bearings being the argument. ISIS are generally dreadful bits of kit IME, so external is the way to go. That said, if you have a spare set of ISIS try and get hold of an SKF BB (hard to get hold of though now) as these are superb and really do last, unlike most ISIS designs.

Not like BMX, no. 2 piece with drive side containing hollow splined spindle that the non-drive side arm slots onto and is secured by two pinch bolts. The only problem with them is that they are more exposed than say a square taper. There's not a lot in it between LX, XT, XTR in terms of shift quality and bearing life so go for LX or XT.

The one place where I would splash out on the top end gear is with some XTR cables. Makes a hell of a difference to shift quality IME.

Nice looking frame, looking forward to see the build.

Jimbo.

No need for XTR cables: just run full length outers, fill them with a light chain lube, and use those "sleeved" Shimano end-caps. Did just that on my Dialled three years ago, and I've never needed to touch them since. Perfect shifting

Just changed the chainset on my bike to a 27-42 double, with a 12-34t cassette from a 24-34-44 triple chainset and 12-32t cassette. Both 9 speed as thats all I have. Havent managed to get out on it yet though as I blew up my park tools track pump trying to pump up my motorbike tyre and have two very soft tyres from a trip along a very thorny track a few days ago. Hoping the ratios might be similar and that i can get out and give it a spin soon.

How does a front derailleur designed for 9 differ to one designed for 10 gears?
I plan to run 2 cogs at the front but undecided on 9 vs. 10 yet.
Could I buy any one and get it to work with either at the rear?

I'ts got a narrower cage if it's 10 speed; if you're running a 10spd cage on a 9spd chain you'll find it hard to stop the chain rubbing at the extremes of the block. vice versa, 9spd mech the shifting won't be as instant.

I'm running 1*10 at the moment on my trail bike, with an 11-36 rear cassette.

Advantages are lower weight and lower cost (no front mech or front shifter), better chain security (thanks to an XC style chain guide) and nice clean handlebars (although I've re-cluttered them up with a dropper post remote).

I've ridden all over Wales and the North/South downs with it and never missed a higher gear unless I'm on the road but the bike isn't meant to be ridden on tarmac anyway!

I've missed a granny gear on some grinding welsh climbs but that's with a 29 lb full suspension bike, on a carbon whippet I doubt you'd feel the need.

Also, a front mech for a double ring setup may have the wider part of the bottom of the mech higher up. I am using my triple front mech and have had to run it slightly higher (with a slightly bigger gap between large chainring teeth and mech cage) than I would have liked to accomodate the chain movement on the larger bottom ring.

Right I haven't bought much, but I've watched a lot on eBay!

I have a set of lock on grips - bit premature but I needed to bump up an order to over £20 to save postage.

A headset.

A Shimano XT direct mount front derailleur.

A Shimano SLX set of cranks with 3 rings.


It's a slow progress, I'm trying to snap up the deals as they come. I'll get there!

Right, I've bought some more goodies.

Answer carbon fibre handle bars. (used).
Carbon fibre seat post. (new).
On One QR seat clamp. (new).
Gear guides/ outers, end crimps and donuts to stop wear. (new).
XT 10 speed rear dérailleur. (used).
10 speed XT cassette. (new).
A pair of SLX 10 speed shifters. (used).
10 speed chain. (new).

I've got a few things to add to the build, but as I've gone 10 speed at the rear, i haven't been able to use as much as i hoped. So I'm using my;
Hope discs,
Crank Brothers Mallet pedals,
Front and rear wheels (not sure of spec),
Saddle.


Having fitted the rear wheel, ir's heavy compared to a XC purpose wheel. My rear wheel for example is build on a D321 rim.
I'm tempted to nab a decent set for a song on the bay, but I'm resisting till now so that I a rurally build it as opposed to spending money where not yet needed.

I'm eyeing up a new Selle Italia saddle due to mine being a bit worn. I think that's a treat I could afford.

Still on the look for a set of forks. Missed out on some Sid World Cups the other day. Then with them I'll hopefully have an idea as to what stem to buy.

Watch this space.

Edit...Just bought a saddle. I should really add up all the bills soon and hopefully not shock myself.

Used carbon bars would worry me. You don't know how they've been treated - clamped too tight, dropped, etc. and they fail spectacularly unlike Ally which tends to bend before snapping.

Lots and lots of stories about them failing on the net.

Rest of the spec looks good.

Hopefully I won't add to the stories! Valid point though. Wish me luck.
