I think the style of fork makes a big difference. This was on my Fuji Track Elite and not really an issue of the magnet being too close, but of the mount being to precariously attached based on the shape of the fork. I tried attaching the mount in both ways, facing in and out...one way simply is not an option because it is angled out too far and when you attempt to side it closer, it won't stay and is even more precarious. So that left only one method....can't recall...I think it's with the magnet cover facing out. You may indeed have a fork shape that just works better with the mount, which is why you haven't experienced any issues. But after 3 knock offs, I called it quits.

Yes that looks like an updated version. All my seated interval stuff is done on it, and it has the ability to adjust to 120mm spacing. I do not have a power meter on my track bike so for dedicated intervals the smart trainer was the way to go. I did attempt standing starts on it once by adding some deck tape to the roller, but the resistance just wasnt high enough even with a 100+ gear on the bike, so all pure sprint stuff i just do outdoors now if its not freezing out.

That's the beauty of my Wahoo Kickr....no wheel slipping on standing starts...I just have to use my road bike. This is where Carleton comes in with his modified Cycleops Pro 300 spin bike recommendation....still tempting. However, I'm no giant legged sprinter power house, so with my Kreitler rollers and the headwind fan resistance unit, fork stand, and fly wheel, I can easily get to the resistance I need for a standing start simulation. It's just a really space hogging contraption.

Very nice set up!

Anyone have a picture of the perkins/perko 33cm carbon sprint bars. They look like a narrower version of the bt sprint bars. Can't for the life of me find a picture of them online.

But these are on Glaetzer's bike. I don't think Perkins ever rode anything that was SUPER narrow, at least not before the Brits went super narrow.

So I don't believe they were ever really used by Shane Perkins, but believe they were made by someone called Perkins. Possibly related?

It's Shane's father Darryl who is extremely well known here and well regarded for his hand made Perkin track frames.

I've searched the group's I'm in before and haven't found anything, but I just searched for any other groups I may have missed and an ad came up from late 2015, but only when I searched "Perkin" and not "Perkins" or "Perko" even though those are the words used in the ad.

anyway I have found pictures now. Many thanks!!

The few people I've talked to that used them have said they were the best bars they've ever used, effectively aero alpinas in regards to dimensions.
I'll try and see how you can get a pair next time I'm out, but from memory there's not that many around

I'm curious as to these handlebars, I can''t seem to find a picture of anything "Perkins", "Perkin", or "Perko".

My guess is it's going to be in the seat tube and head tube angles for the Sineo - most track frames are 74 deg seat tube, head tube angle depends on the size of the bike a bit. The Sineo has a 75 degree seat tube, and there is a rule of thumb that one degree change in STA or HTA equals one centimetre of reach, so that would (artificially) add to the reach number listed. Also, with a slacker seat tube angle, as the saddle goes up, compared to a bike with a steeper STA, your saddle gets further away from the bars by comparison so that helps lengthen the bike too - they are things that don't really show up on the frame's dimension drawings.

I'm not sure how the head tube angle influences things, perhaps someone more astute with maths could fill that one in.

I have an older Ridley Oval, which is really weird geo wise. I'm 182cm, and the bike has a 54cm top tube, 170mm head tube, and the highest standover of any of my bikes (normally 57-58cm) BUT the bike has a crazy steep head tube, and a 75.5 degree seat tube - with a set back post, it has the same saddle to handlebar distance as my other bikes. I do have a fair bit of seat post out, which puts me further back and increases the effective reach.

My weight is balanced when I'm riding, and because of the weird angles the wheelbase is nice and tight, but the reach number for that frame is about 389 , whereas the reach for my other bikes is comfortably over 410. If I'd measured the bike before I bought it, instead of just test riding it, I might have gone down a different path, especially since I also have a 140mm stem and Nitto B123s on there, and it is *nearly* long enough.

I am looking around for a new bike (who isn't right?) and I would much rather be on a more standard geometry bike, partly for a bit more adjustability, but partly for a more sensible standover and shorter head tube. Its been a good bike so far, really it's been good enough for me to wring myself out in the middle of the pack which is about the limits to my racing, but that's my 2 cents. I have no idea why they designed the bike the way they did.

The Perkins sprint bars

If I didn't know any better, I'd say that those are BT sprint bars:

You can see them in use here: https://www.youtube.com/watch?v=xRvnGsPF7k0

The S1NEO looks to be a generic road TT frame repurposed as a "track" bike.

75 degree seat tube angle and 72 degree head tube angle are angles for use with aerobars. Period.

I've never seen Pervis ride one outside of an ad. Come to think of it, I've only seen him standing next to one.

I'd pass on it.

Very similar to the bt bars, just a smaller width and I think maybe smaller drop and reach but not completely sure.

I managed to find someone selling a set of them and they are in the post now 😆

The Perkins don't curve unlike the BT

Good catch!

They'll not be finished as nicely as BT's, but you'll love them

Fair enough - I thought it would be ok as looking at the Argon 18 Electron Pro frame that Glaetzer is riding at the moment, that has 76 degree seat tube and 72.7 head tube, so i assumed this would be workable as its "similar".

What do you think about the geometry angles of the Look 875 Maddison? I expect its more tuned for endurance track riding but i would primarily be using it for Sprinting? My current Planet X Track Pro is too short in reach for me to get into a long & low aero position for sprinting.

Olympus has a bar option: https://olympusspeed.com/collections...rack-handlebar

Kaben, check out a Dolan DF4 (or DF3). They are pretty long, low, and affordable. Yes, there are some known issues - some have seat post slippage, but if you torque to spec (17-19nm) it's not a huge issue. And yes, the dropouts are short on the newer version.
