Mark W Posted August 2, 2016 Report Share Posted August 2, 2016 Some news from Jitsie which might be of interest to some - they're launching their range of frames, which you've probably already seen people like Adam Morewood and Nico Vallée riding. The 20" frames are first up, in either 970mm or 1010mm WB options, in 4-Bolt or Disc. They're a pretty simple design, but should hopefully be nice and tough. Internal headtube, 116mm spacing, 68mm regular shell, 4-bolt Ozonys-style bash mount - compatible with most setups. One slightly unique thing about them is the seat tube arrangement. Shown here they have a silicone bung covering the top of it, but Jitsie are also launching a seat/post setup so you can run a seat if you want to. Geo, measured with the Jitsie Varial forks, is: WB: 1010/970mm CS: 350mm BB: +80mm HA: 71.5° Reach: 600/570mm Quote Link to comment Share on other sites More sharing options...
Canardweb Posted August 2, 2016 Report Share Posted August 2, 2016 Is the seat post a standard diameter one? Quote Link to comment Share on other sites More sharing options...
Mark W Posted August 2, 2016 Author Report Share Posted August 2, 2016 It's 25.4mm-ish. Not sure if Jitsie are planning on putting out a quill style post, or whether the seat tube tapers slightly so you just wedge it in... Quote Link to comment Share on other sites More sharing options...

Somehow I think this is a feature that won't actually be used. Quote Link to comment Share on other sites More sharing options...
jeff costello Posted August 2, 2016 Report Share Posted August 2, 2016 totally. but they could sell it as weight reduction. please, please someone post a pic of complete bike with seat! Quote Link to comment Share on other sites More sharing options...
Mark W Posted August 2, 2016 Author Report Share Posted August 2, 2016 As and when we get the seats for the frames I expect we'll be posting up about them, so your wish will be granted at some stage... Not 100% sure on the value of it, although I guess as Jitsie aim at the mototrials guys too having a more 'normal' looking bike/just having a saddle might be a draw for them. 1 Quote Link to comment Share on other sites More sharing options...

Dman Posted August 3, 2016 Report Share Posted August 3, 2016 Jitsie website, no mention of a 24", only one size 26", but 3 sizes of 20" 20 comes in 1010, 970 and 920, they only show the 920 with hs mount no disc version. @Mark W Quote Link to comment Share on other sites More sharing options...

Mark W Posted August 3, 2016 Author Report Share Posted August 3, 2016 Ah, cool - I haven't actually checked their website out before. Retard... And yeah, plenty of 20" options! Bearing in mind 2 of those 20" sizes come in 2 different brake mount options that's a lot of frames. With the disc mounts it's kind of a tricky one. For a standard 160mm post mount it's not too bad, but for a +20mm style mount they're pretty hefty. Adaptors going from IS to Post are also a bit more common. I'd imagine more shops have facing tools for an IS Mount as well (plus facing PM frames sucks anyway). We'll see what happens though I suppose, PM does seem to be the preferred choice nowadays by a reasonable margin. Quote Link to comment Share on other sites More sharing options...
Dman Posted August 3, 2016 Report Share Posted August 3, 2016 It just looks really strong how they have done it, dropout, mount and the brace in one piece. Quote Link to comment Share on other sites More sharing options...
Mark W Posted August 3, 2016 Author Report Share Posted August 3, 2016 That is true, although that's essentially the same as the +20mm IS mounts on the Skye V3 and the new Fourplay frames (which have the same dropout, albeit machined out for a 10mm axle): 1 Quote Link to comment Share on other sites More sharing options...
Bottleneck Posted August 3, 2016 Report Share Posted August 3, 2016 Vašek Kolar has a precedent of riding a mod with a seat. He might like this idea being brought to light. Or not, he seems rather happy with his Monty Quote Link to comment Share on other sites More sharing options...
Dman Posted August 4, 2016 Report Share Posted August 4, 2016 It's just the no adaptor part that I like the sound and look of looks clean. 1 Quote Link to comment Share on other sites More sharing options...
Mark W Posted August 4, 2016 Author Report Share Posted August 4, 2016 That's what I meant before though - if you're running a 203mm, you'd still need to run an adaptor as they're usually just in either 160mm or 180mm positions as standard. This is what the Hope +20mm mounts look like to give you an idea: We've got info on the 26" frames up now for those interested. Geo, with a 400 x 35 fork, is: WB: 1085mm CS: 380mm BB: 70mm HA: 71.5° Reach: 665 or 670ish at a guess Weight: 1.6~kg (TBC) They're £329, so a little more than the 20" frame but still pretty cheap for what's a nice frame. 1 Quote Link to comment Share on other sites More sharing options...
Dman Posted August 4, 2016 Report Share Posted August 4, 2016 I think I could manage on 180s 1 Quote Link to comment Share on other sites More sharing options...
Ross McArthur Posted August 4, 2016 Report Share Posted August 4, 2016 Plus all the forces are going directly downwards into the frame instead of the two bolts taking all the load on IS with adapter. Hmm, might have to get Marino on the case so see what we can do to try a steel PM arrangement. Speed dial 1. 2 Quote Link to comment Share on other sites More sharing options...
Mark W Posted August 4, 2016 Author Report Share Posted August 4, 2016 I expect the results will be interesting. EDIT: ...should probably point out that's mainly because all the steel PM mounts I've seen haven't been great. I think it works pretty well for aluminium where you can get tech with the shape and have a pretty sizeable/supportive mount, but not so much with steel. For the adaptors, the majority of ones I've seen break have tended to go in the 'arms' rather than the bolt part, so with how tall that Hope mount sits I think you'd still possibly have similar-ish issues. That said, Hope adaptors seem to be some of the best out there so it'd probably be fine. Quote Link to comment Share on other sites More sharing options...
Felix_HBtrials Posted August 5, 2016 Report Share Posted August 5, 2016 I think all brakes should be post mount and frames IS That was threads are only in the brackets, no way you can ruin the frame or brake And also it's easier to go from 160-203mm 2 Quote Link to comment Share on other sites More sharing options...
