Welcome to the forums. This is not an SHX but a frankenebiked PR-10 with the decals and paint removed. Do you know if the wheels are OEM? Value is highly dependent on the local conditions, so we'll need to know where you live.

In my hot market you'd get $250 to $350 with proper marketing. The latter would be much harder to get. This assumes you install a front brake caliper. You might get the $250 with cheaper replacement parts, selling off the Dura Ace separately.

The wheels are mis-matched. The rear is a Dura Ace hub with Matrix glue on rim, and the front is a Dura Ace hub with Mavic glue on rim. I just measured the frame and it's a 58cm frame. I live on Vancouver Island in BC, Canada. I plan to take some more pictures of the bike this weekend, and I will post them on the same set on Flickr. I'll try to get pictures of the serial number and better close ups of the components. I've removed the fenders and pump, changed the seat, and installed the front brake. I guess I shouldn't have said "full Dura Ace" earlier as it is missing some of the required components.

It's good to know it's a PR-10 though, thanks for the help.

T-Mar

It should be circa 1978-1980. The wheels have been rebuilt. Tubulars are a hard sell. Even though it is one size too big for me, I may be interested. My son goes to UVic and he could bring ot back with him next summer.

Hi everyone! I'm new to this forum but I want to write that I'm really impressed with the contributions I've read. Here are two views of my Sekine:

I dragged it out of the basement and cleaned it up. Nothing's been done to it since my father gave it to me new in the 70's. I now have it in the shop for new tires, bar tape, cables & housing. Looking foreward to getting her back on the road where she belongs.
It's got braised cable guides (if that's what they're called), the Medialle head badge, Simano Lark & Thunder Bird DR, etc. One curious detail is the shorter Sekine-Canada frame decal.
I read all the posts here but I'm not sure of the date/model of my Sekine. The serial number begins with a "Z". Any help here would be hugely appreciated. Cheers-- Lori

As usual, I'm late posting a reply. My first thought was that frame is a PR-10, but that's already been said. I would buy it from you, but 58cm is also too big a size for me. The cranks and pedals would be my second big concern. I do have a spare Dura-Ace front brake caliper in a box (maybe even matching), if you come through Vancouver you can have it. Such a sweet, sweet bike though, thank you for posting nice photos. What's the serial on this one?

T-Mar

Lori, welcome to the forums. Your bicycle is a 1975 Sekine SHC 270 in the 214 blue green finish. This was Sekine's upper entry level model and arguably the best selling bicyle in Canada during this period. Original price in 1975 would have been ~ $150 CDN.

The bicycles would sometimes come through with the short seat tube decal (which was typically used on the SHX model) and if you go back through the pictures, you'll also see two different styles of down tube logos. They would often be mixed, even within a shipment.

Yeah, the Dura Ace cranks are nice, but they definitely only seem to fit the Dura Ace pedals due to the huge pedal bolt size. I would be very grateful for a matching (or even another year Dura Ace) front caliper, but I don't think I'll be in Vancouver any time soon. Thank you for the offer though. Perhaps I could pay you via PayPal to have it shipped?

I meant to take more pictures of the bike last weekend, but never got around to it. It's at my shop at my parent's farm, so I can't get to it easily. I will make sure to take a photo of the serial number next time I am working on it though. It's really too bad it's too big for me. I'd love to keep this as my main "nice bike".

My wifes single speed, and my mostly original SHS.
Y9 5053 Y9 5267

This winter on my bike, I'm going to put on new tires, brake levers and maybe
different pedals.

Love the SHS 270! I am currently trying to bring back a similar SHS. I am in need of a seat post, a stem, and bars and brake levers. The seat post in particular seems an odd size. 25.8-26mm?

Hi T-Mar et. al.,

I have a Sekine in desperate need of some love. The sn is Y2 0634. The bike is in a real state, having been spray painted twice. The components seem pretty entry level, Shimano tourney, fingertip shifters, 27" wheels etc. but the frame is quite interesting with forged Shimano drop outs and columbus lugs (I think). What I would really like to know is if the frame is butted chromoly or just hi-ten. Year and model would be interesting too. You seem like the Sekine guy(s), so I thought I would venture to ask.


All the best,

I think this is the same as my bike, except mine has white and blue spray paint indiscriminately covering every surface of the bike, including tires. Same Sekine Canada/Japan headbage, same SR crank and rings, same rear der. same lugs and forged dropouts. Again, my serial number is Y2 O634. Any hints to its provenance and model much appreciated.

The 1974? "SHS271 Deluxe Lightweight 10 Speed Machine" serial# Y90851 is nearly completed! The original bars were found by the previous owner and almost all the original parts were salvagable save for the seatpost, brake levers, pedals and saddle. The brake levers are Weinmann from a similar period Raleigh.

Tom the tank

Here are some (bad) pics.


I would really like it someone could identify the tube set. I removed some of the spray paint with nail polish remover, but I've taken some colour out of the transfer stickers in doing so. I am sure the lower sticker reads Butted Tubes/Champion/Cro-Mo Steel. Still not sure exactly what that means. I pretty sure that it means Tange, but unsure if it is just the seat tube, main three tubes or everything, and what quality. I've read a bit about Champion 1-5 but don't see any indication of this on my Champion sticker. Also hoping that someone out there can ID the model. My optimistic guess is a SHT, but still unsure. Also an approximate date would be great.

I plan to strip the frame down and give it a new life. New paint and 700c wheels. Maybe FG, maybe just reuse all the original drivetrain. See what I can dig out of my junk drawer. I've been thinking a lot about steel randonneurs, and the Universe has answered.

It has been very interesting reading about the history of this Canadian/Japanese enterprise. I hope this thread never dies.

RodoftheFlies

Wow, that came out very nicely. Did you use a 26.0mm seatpost? That's the best fit I could find for a similar model. The stem looks a little too high-rise, though.

browngw 

Thanks for the kind comments.

After the pinched in seat tube was spread back out and everything cleaned up a 26.4mm seat post was a perfect fit. I spent a lot of time trying to locally source a 26.2mm post and could have ordered it, but only in black. One nice day in Dec while I had the frame stripped down, I took it down to our local Home hardware store which has sold Norco products for many, many years. I found an alloy 26.4mm post and it fit like a glove! $16.99 well spent.

The stem is SR from a Raleigh in the parts bin. The original is in a landfill somewhere. It has a long post and short stem by current standards but I find it comfortable. The frame is 54cm, a little on the small side for me but I have the saddle set at my height so I now the bar is level with the saddle, the way I like to ride. I'm definitely an "unracer". I will probably keep this bike because I like its character and fine workmanship.

The total build with pedals, less tape, is 26.6 lbs. The frame alone was 4.6 lbs.

browngw 

To the best of my knowledge, the frame for the mid to higher end Sekines was labeled "Champion Butted tubing Cro Moly Steel" I have included an image of what's left of the sticker on my SHS271. It also came with the Titleist RD and Shimano SF dropouts with adjusters. Most likely the same frame.

Tom the tank

Thanks Browngw and Rod for the feedback. My bike has been identified as a c.1974 double butted cro-mo SHS271. I stripped off everything but the BB and headset today, and confirmed that the original tourney centre pull brakes have plenty of reach for 700c wheels. I think I read on velobase that the tourney are identical to the Dura Ace centre pull calipers. The fork ends are too small for the front axel wheels I have kicking around, so I guess they are 9mm (or whatever the old standard was). I'll probably build a wheel with the original front shimano hub. It spins well, and I won't have to grind out those nice fake campy forged fork ends. Now the fun begins. I'll post pics of progress.

For the Sekine fans who might have missed seeing my SHL270 Sekine Mixte, I will repost here. It is a really nice bike but will be for sale soon. No family has stepped up to the plate, I have a nice Raleigh Mixte and mrsbrowngw prefers her 76 Raleigh step through.

This bike is a Canadian made Sekine from around 1974. As far as I can tell it is a SHL 270 (Ser.#7A43524 ). The friend who gifted it knew little about it except she thought that her father had removed the drop bars. The cheap replacement brake levers were badly rusted which was not in character for this well finished bike so that could have been the case. The fork is Tange 6 chromed. Frame size is 21 in.

Altogether I have $75 dollars in it and now I have to find it a good home. Many hours have been spent bringing this one back, but it is this years first "winter project" and it is a gem.

I am new to this site and, reading these posts, I got to wondering about my Sekine PR-10. I bought this brand new (factory order) from Lifesport in Winnipeg in April 1981. As far as I know, it was one of the last bikes made at the Rivers, Manitoba plant before it closed (I think it was built there, anyway). What got me wondering was that this was sold to me as a re-developed PR-10 (we called it a PR-10B) - sort of a new development. The bike is pearl white and came with Shimano Dura Ace gear, including these funky (at the time) pedals that fit the foot (integral toe clips). Also had Araya titanium wheels. I still have the bike, which has been in storage for a while, but everything is complete and road worthy. Is this a rare bike?

To reply to this three-year-old inquiry of yours, mojoliveshere, I can tell you that your frame is a "white gold" SHS-271 63cm model.

The frame's Y8 prefix suggests that the frame was manufactured in August 1974. You can tell it's an SHS by the crankset (Sakae SR, larger sprocket not interchangeable, and the "safety" brake levers).

Your Y8 2586 frame was built probably the same day or week my current frame, a dark red SHS-271 63cm model (serial Y8 2559) was. My frame cosmetically is worse for wear, but remains mechanically sound. This dark red frame is a replacement for my forest green SHS-271 63cm model (serial Y10 0277, October 1974), which was stolen from me in Toronto on November 1st, 2013.




Until 2007, I owned a dark blue SHS-271 58cm model (serial Y4 6720, April 1974), which was also stolen in Toronto. The most noticeable difference about that blue frame was it was detailed with the white art deco enamel on the down tube, not the more common, wide eurostile-like decals.

Hey browngw. That's a spectacularly maintained SHL-270 mixte frame!

I'm looking at your serial. If you still have the bike, could you take a second look at the frame serial? I'm willing to bet that the first alphanumeric in 7A 43524 is more than likely ZA 43524, where the "Z" may be very poorly stamped.

I say this having just purchased an SHL-270 mixte frame in forest green.



It's in near-mint condition, with a couple of small paint scratches and almost no exposure to the elements. Its serial is ZA 32608.

My guess is that the Sekine mixte frames from that period, along with the forks, were being manufactured/sourced by Shimano, as these use the same styled date codes. (other Sekine frames I've owned have had at least the forks forged by Shimano). The original Shimano hubs on this above mixte frame are "Z A" (1975 January) and "Y K" (1974 November).

If the frame date codes are correctly Shimano, then both your frame and mine were manufactured in January 1975 for probably the 1975 model year.

If my hunch is correct, you're likely to find a weakly-punched "Z" and not a "7".

Bikes and Jeeps, both of these forest green SHS-271s from September 1974 are gorgeous! If you scroll back about two replies from this, you'll see the photo of my forest green SHS-271 from October 1974 (Y10 0277) which was stolen a few months ago.

Thank you for sharing these!

accozzaglia

beanteck, this is definitely an amazing SHS-271 with a 58cm frame from probably November 1973.

Probably the best way to parse the serial is to add a space: #X11 07116.

X is the code for 1973, and 11 is probably for November (Shimano probably had some involvement in it; check the forged fork drops to see whether "Shimano" is radially stamped; I'm guessing it is). Also, check your hubs. If original, they'll also be made by Shimano and may have date codes which may be "X [A-K]", possibly even "W [A-L]".

Tom the tank, That frame, Y2 0631, appears to be an SHS-271 manufactured probably in February 1974. It's an SHS, not an SHT based on the SR crank set, forged drops, and "safety" brake levers.
