    From the pictures it seems like the rear triangle could be opened, is this the case? I'm looking for a new frame to build a belt driven alfine commuter. If this rear triangle could be opened all that is missing are the horizontal dropouts, any plans for horizontal-dropouts? (From the pictures it seems that at least the drive-side hanger/dropout is changeable, but I cant find a good picture of the non-driveside..)

  • BikeJon

    Looks great. I'd like to buy the fork separately too. It would be great to see a future version of this frame having rack and guard mounts as well as a horizontal dropout option.

  • Mullet

    How come the pic of the frame alone appears to be a different frame than on the made up bikes. It looks heaps nicer with the weave, the curves and a much smaller headtube height. Actually it looks a bit more like the 465 frame.

  • Alan Dorrington

    I've got the pre-production sample but I think it is the same on the production version - it's a carbon steerer and an expander plug works fine.

  • steve cudnoski

    Does the fork have a carbon or aluminum steerer. My frame is arriving on Friday 12/2 and want to be prepared with correct star nut or expander plug. Thanks

  • jez cook

    Further to Dreg's message, I can confirm that I took my frame out of the box this morning and my immediate thought was 'Wow, this is properly light...' Highly unscientific, but it's like when I picked up a mates carbon front roadwheel the other day. What is the situation with the self adhesive stickers? Will they be available soon? Thanks.

  • chills

    If, as advertised, this was to be used as an all round bike for commuting and touring. What mudguard would you be able to fit, would something like the Crud RoadRacer fit?

  • Dreg

    For those of you wanting weights, I get 1.230kg for my 56cm frame and 0.490kg for the forks.

  • Tom Ruane

    Any chance the vertical dropouts can be swapped for horizontal for an alfine 11 hub? i'm not keen on a tensioner. Thanks

  • Matt S

    So you have the frames - how about getting some weights up on the site? I'm curious about the 56 frame and fork weight... Holding off with my purchase until i know the weight

  • MattW (On-One Team)

    full builds have just gone live folks !

  • JonB (On-One Team)

    I'm afraid not at present Stephen. The only XL bike we have is currently out on test. More details soon!

  • Stephen

    I might of missed it but any idea of the standover height of a XL bike?

  • JonB (On-One Team)

    Afraid not Karim- we won't have the exact frame weight until they arrive here.

  • Karim

    Any word on aprox weight yet?

  • DH (On-One Team)

    Available only as frame and forks in the first instance

  • Adam

    Any idea when the fork will be available separately?

  • JonB (On-One Team)

    Hi Adrian. The wheels are On-One XCQR 29er wheels- lightweight and perfect for cross. You can buy them here:

  • Adrian Shields

    What wheels is that bike? Im trying to find a decent pair of disc break cycle-cross wheels... but don't really know what to look for.

  • JonB (On-One Team)

    Sizing guide now up on the product page...

  • JonB (On-One Team)

    Hi Jay- the front mech roller is needed for some front mechs. We will be stocking them.

  • Jay

    I notice that in the photos there is a extra clamp at the bottom of the seat tube for the cable routing for the front mech. Is the cable routing built into the production frames or will I need a additional clamp as in the photos?

  • JonB (On-One Team)

    Yes Tim, 2 sets of bottle mounts.

  • Tim

    Does it have any bottle mounts ? The option of a bottle makes it good for training in summer

  • shoutstone

    What's the weight??

  • JonB (On-One Team)

    Well, to a certain extent 29ers and cross bikes have different geometry too- to allow for different riding positions with flat or drop bars. Plus, obviously tyre clearance (both longitudinal and lateral) needs to be much greater for a 29er.

  • ThereseS

    At what point does a 29er become a CX bike ? Is it just the bars and tyre width?

  • JonB (On-One Team)

    Hi Simon, initially the Dirty Disco will be frame and fork only (ie not fork separately). The fork is a tapered 1 1/8 to 1 1/2 in carbon steerer. Will inform of weight as soon as I have it.

  • SimonT

    Will the fork be available to buy separately? I presume it's a standard 1 1/8" steerer? Weight? Well done for ditching the BB30 on the frame, and 160 discs were the right size choice. Swap-outs would have been a bonus...

  • JonB (On-One Team)

    Yes, it is disc only....

  • Matt S

    I'm about 182cm tall and I have a Planet X Pro Carbon SL in size L which fits me great with alot of seatpost sticking out. Which size do I need for this bike - 56?

  • JonB (On-One Team)

    Hi Bruce. Drawings show 40mm clearance within the 46mm cross section. However it's always best to measure your actual tyre rather than going on spurious sidewall markings. 35mm cross tyres should fit easily though.

  • JonB (On-One Team)

    Hi Marius, it's vertical drop-out only. You could of course run Alfine with a chain tensionner. And you could use clip on mudguards too...

  • JonB (On-One Team)

    Hi James- no, there no rack or mudguard mounts I'm afraid.

  • FT

    Please tell me this isn't disc-only...

  • BruceF

    +1 on the mudguard fittings plus what are the largest tyres the frame can accommodate? This could make an excellent Winter training bike.

  • Marius

    Dirty Disco rings all the bells, but does it come or can I fit a horizontal drop-out for an Alfine 11 experience? If I can, which item would it be in your webshop?

  • james

    in the blurb you mention that this frame would be flexible enough for commuting and touring ... does it include mudguard/rack attachments? I don't see any on the prototype pics I've been waiting fro something like this....

  • matt

    do you sell the wheels featured on the bike ridden by alan?if so, how much are they? cheers matt

  • BrantR (On-One Team)
