from the previous owner forcing the pump on.

More likely from tugging it off (ooh er)

Raltech cover? Take it off and add a layer of carbon around the hole on the inside face to reinforce it

Nah it’s an actual disc wheel.

Get yourself a good crack-pipe adapter in advance of race season 👍

You might need to explain what that is.

Goes on the end of your pump

Something like this

Or ideally one like this if feeling flush - A locking one will mean you can use 2 hands on your pump instead of having to hold the adapter on to the valve.

I’ve seen those silca ones - I seem to remember someone sourcing imitation ones from china. £65 is a bit rich for me!

These are a good alternative

The Silca is already an imitation of the original Hirame Yoko 🙂

There's a guy on the TT forum who sells Hirame (or Hirame style heads). I'll try to find him.

Personally I wouldn't worry about the crack, but yes, something to stop it spreading will never hurt. You'll probably find half the field will have similar on their discs.

Didn't take me long :oD

Wonder if he actually sells any when Singletrack are offering the Truflo version at £16

Tester being the MVP right here
edit: also @danb . Thanks!

Also thanks everyone for making me less worried about the crack! Never had anything carbon apart from one set of forks - definitely paranoid. Steel is real etc.

I've carved much bigger lumps than that out of my disc to make the hole big enough for a Yoko crack pipe. Generally, the disc types which don't rely on tensioned skins are a very inefficient design for stiffness, so they end up very overbuilt for strength.

I had 11 in a studio and I think 9 in this 1BR. Try harder.

I’ve been offered a PDQ PB frameset, with brakes are they any good? Or will I be buying tat? I can borrow a cockpit from a friend. I’ve got some cranks, chain, 135 spaced fixed wheel and a front wheel. Is there anything else I’d need to have a go at a 10miler fixed?

You'll need a 130mm OLN wheel for that frame. The dropouts look very short, so it's probably going to need a magic gear. You'll need a helmet and front and rear lights

will I be buying tat?

Well, yes, obviously, but it depends on the price. You can typically get an old P2 or P3 frame for £500 or less once you've parted out one of the complete/partial bikes on ebay, so you probably don't want to pay more than half that for a PDQ

Cheers, can do the wheel as I have a set of 120mm/130mm/135mm spacers. I’ve got a lid and some little lights. Maybe a 1/2 link and a bit of track slack will get the chain sorted?

The frameset and brakes are a bit under that so they’re in the right ballpark. I was getting drawn in by the £1300 rrp on the frame, but looks like that includes the bars. Hmmm

I've got one here and it's been fine. The mould has been used by loads of other brands. The brakes should be trp ttv's they're fiddly but work OK the springs don't last forever but are available still. I'd say anything under £400 for one is a decent price

I have a Vitus Chrono TT, which looks awfully similar (the model I have). I bought it for £300 as a frameset with brakes + bars + TT extensions, but in a very neglected condition. Cable guiding to the rear brake is not a nightmare, brakes are OK to setup. Very happy with it, and I'd need to add a good 100 watts to my FTP before this frameset becomes the limiting factor :)

I'm up for selling my 2012 P3 frameset for well under £500

Oh my this was good info 2 months ago. Ah well I can bragg about my hirame 😥

No TT bike for me then, the car needs a new exhaust :/
