H plus son TB14

Have you bought your TB14s yet ed?

not yet, still in two mind about it, especially when learnt it's not as stiff as says, Open Pro, so I'm having a good mosey around to see what other option before deciding on the TB14.

I quite like how my 25c behave with 25mm wide rims, and have a lovely shape as well that make cornering a breeze, I'll probably decided on the trustworthy Mavic A319, or go for the TB14.

I thought the A319 was a much wider rim which Mavic only recommend for 28mm and higher? I used to have one and it sat very well with a 32mm tyre but I the guy that built it for me recommended nothing under 28mm.

theres a halo rim. for about 20 quid, white lines http://www.halorims.com/products-details.php?id=RMHAWL76 any good ?

600g seems pretty porky

or velocity synergy , they any good ? those tb14's look really tasty though............

Even so, it doesn't mean you'll have a catastrophic failure when running less than 28c.

The A319 is very noticeably wider than an Open Pro. It also weighs getting on for 1.5 times as much.
The A319s are so wide in fact that I am comfortably running 47c tyres on them.

Not exactly a natural choice between Open Pro/TB14 or A319

Open Pro is 19.6mm, TB14 is 23mm, and A319 is 25mm.

The jump between TB14 and A319 isn't that much compared to the Open Pro/TB14.

picture speak a thousand word; A319 with 26mm tyres, a perfect U shape;

"Open Pro is 19.6mm, TB14 is 23mm, and A319 is 25mm."

They are the external widths. An Open Pro internal is something like 13mm whereas an A319 is around 19mm. And combined with the 1.5 weight difference still not a natural choice between Open Pro and A319 to me. A wider rim that compares better with Open Pro is the A23 isn't it?

But yes, I would think that under 28mm could be used on an A319 as your picture demonstrates.

I don't really notice the weight that much TBH, especially when the tyres felt more like tub.

I think the internal of the TB14 is something like 17mm.

Fair enough, it's just that I tried a 26mm folding Panaracer on the A319 and had a world of hurt trying to get it to seat properly. Given that Mavic took the time to put a sticker on there suggesting I didn't I gave up on the idea. The same tyre worked fine on my OpenPro on the Fixie. I'd also have to agree with other comments re the weight difference as I found it very noticeable. It's a good rim but I just don't see it as comparable to an OpenPro, if it works for you then go for it.

^ You're right, it's not really comparable. The OP is an entry level road rim. The A319 is a touring rim.

The more I look at Velocity's rims, the more I struggle to see why you'd choose Mavic's. Admittedly I haven't ridden any Velocity's for any length of time, nor have I built with them, but they carry a good rep.

I'd be looking at something like the Velocity Dyad* (480g) over the A319 (and probably the OP for the city).

The Hson's are a good choice, mainly because of their looks (not a criticism).

• ontop of that they come in 27" and 32h, 36h, 40h, 48h.
  

Price really, rims are £30 a pop compared to the £50-60 of the Velocity A23, that why I went for the A319 in the first place.

Other choice is the DT Swiss TK 540 at 24mm wide and 540g, like the look of the Velocity Dyad thought.

That's true.

I didn't realise the Velocity's were that much.

But if you're at that end of the price range are you not just better off with Rigida's? All just thoughts really - I started to look at alternatives to Mavic, when there were all those internet rumours about poor quality control on OPs, coupled with the slight up-shift towards the £40 mark... and realised that there were other sensible choices out there at the low/entry-level.

...and incidentally I just found this website: http://vintagebikecave.com/products/rims/

A lot of tat, but a few nice rims.

I didn't realise the Velocity's were that much.

They are not, they are 40 quid.
The only reason I went for A319s over A23 was due to being extremely tight and wanting to use my existing spokes and hubs from a fairly new wheelset. The A319 were exactly the same ERD and the A23 wasn't. Presumably the A319 would also be stronger/take more abuse but that is not much of a concern as I never broke Open Pros when I used them.

A319s are designed to carry load, and are pretty darn solid. Wether that translates into a solid off-road rim, is another thing. Still, the weights there for a reason (plus for off-road use, the added traction of the added width of the tyres is a bonus)

So Open Pros are entry level and suffer from poor quality control?

I have always thought they are the yardstick by which others were measured.

Ive been training on tb14's at an outdoor velodrome, very happy with them. perfectly round and no they dont flex, Im 18.5 stone and Id notice during sprints. being a 14mm high box rim it might show signs of flexing prebuilt but thats just the nature of the design, once spokes are brought up to correct tension they are plenty stiff.

Araya njs rims are lighter with similar low profile design and they flex more than tb14's, if you ever look at an ex keirin used hub youll notice the marks on the flanges from the spokes, they use very high tension to get the stiffness up which cause the spokes to cut into the metal.

I'm very happy with mine too - they're on my road-bike. They're very comfortable I find, and feel good and strong.

They are not, they are 40 quid.

Just noticed that, unmachined sidewall.

Still £20 more and that £20 can get me the spokes/nipple.

So Open Pros are entry level and suffer from poor quality control?

The quality control issue may or may not have been true, if it was true, it may well have been resolved - I really don't know. But yes they're entry level in terms of road rims. I'm not saying they're shit by any means, but they're just a box section alu rim.

And I'm also very happy with both of my sets.

they arent entry level, open sport is entry level, open pro is just about perfect for what it is. open sport is weaker aluminum, single eyelets and defintely doesnt build up as nice. the brake groove is annoying too

dt swiss rr465 is supposed to be better but I havent used one personally

Just noticed the rr465 are reduced to £29.99 on Planet X, suddenly an attractive alternative

saw that yesterday, best price Ive ever seen them in any sale.
