Carrying on from my earlier post Mercian have told me they've a few pairs of 28/28 GP4's.

Alternatively they've got some Reflex's that can go in my frame box. Roughly the same price.

What's the weight diff? Weightweenies show GP4's as 400g and I gather Reflex's are 375g. For some reason I thought GP4's were more like 500g each??

Would I regret getting the GP4's over a more modern rim? The GP4's do have retro appeal are period correct for the frame.

Thoughts very much appreciated.:p

I had some GP4's, laced 32 cross 3. Maybe the most bulletproof set of wheels I've ever owned. Rode them for years and only "trued" them because I was anal.

That being said, they are a little heavy, around 400 to 430g. Mavic would always quote weights as +/- 10%. Doesn't sound like a lot but that is 40g's. But considering 430g's makes a "light" clincher, hardly a deal breaker.

I don't know how much you weigh or how "hard" you are on wheels, but a 28 spoke GP4 would be a nice set of wheels - and "period correct.":thumbsup:

28 hole gp4's - perfect wheel.

The original GP-4's were about 405 grams. In the last few years of production, they changed them with a slightly more square and wider box section, and the weight went up to 480 grams. I'll see if I can scare up some pics when I get home as to the labels but basically if the Mavic label is red or red and gold, it's the old one. If it's blue/violet and yellow, it's the new one. I have both and the old style is one of my favorite rims. That being said, the new style is very nice but heavier.

The rim one up from the bottom is the newer style GP4.

Thoughts very much appreciated.:pKinda depends on what kind of gearing/components yer running...

I had GL330s on my 9sp cross bike and always had issues with em (at 190-ish). Put some Escape rims on there and its been fine ever since.

Alternatively, some Wolbers or Sun rims in the semi-aero profile (similar to the Escape) would do OK with the more severe dish of today's hubs. Still period correct which is a plus.

If yer runnin 5-7 speed gearing, the box section rims are gonna ride a little softer and prolly be fine.

HTH,

It's a bit of a mix. The hubs and drivetrain are all 10 speed. But the rest is older stuff, quill stem, regal saddle, Super Record seat post, 9 speed down tube shifters converted to 10 etc. So neo retro hence my 'period correct' interest in the GP4's. The frame is 753 built up and painted as per the Mercian '81 catalogue.............Wonder if the dishing point you make is going to be an issue???

I would not compare using GL330's (at 190.lbs) for cross with GP4's for the road. I've used GL330's on the road and for me, it's a racing rim for the road. MShaw did not mention what the issues were but if they were ferrules pulling out of the rim, the Velocity Escape's got more material up by the nipple hole and more appropriate for his use/style.

The dishing on the drive side for a 10 speed, especially with 28 holes, will have a fair amount of tension but I wouldn't be put off by the GP4's, either model. How many stone are you tipping the scale at these days?

The ole DannyBoy is about 13 stone dead (83kg), at a fairly reasonable 14% body fat so the geezer at the gym tells me. Should be higher with all the business lunches I've put away over the last 10 yrs. Talking of which it's Crayfish (spiney lobster) special time down here in NZ and I'm going Thursday, Friday and Tuesday (last year I managed 6 visits)!!! Check this out;

By the way Boneman is that splendid collection of rims yours???? If it is you are one lucky man............................................... .................:D

Yes, all mine. Also have 6 Campy Omega tub rims, a set of Campy Clincher Omega rims and pair of Mavic SSC 28 rims. At some point I will return to the States and spend my retirement riding and also either building wheels or just selling of the rims on EBay.

I've seen that pic before, and it looks kinda like my stash of rims before I started selling some of em... I still have about an 8" deep stack of tubie rims in storage in Phx. Some Campy, some Mavic, some misc.

My pride and joy, however, is a set of 3 Omega XL clinchers. Little wider and a little lighter than the MA40s. Should make into a GREAT riding wheelset once I get around to where I can build a wheel with em. Have a pair of NOS Mavic 571/2 hubs waiting for em.

AFA my issues with GL330s, they just wouldn't stay true. No matter how I tried, I'd hafta fix em darn near every ride or so. Front was fine, just the back gave me fits. They worked better on a pair of American Classic hubs with the NDS flange moved inboard. Less tension differential maybe? Been a few years since I've ridden those wheels...

--------- i apologise for the thread jack mate, but...------------------------

since u guys appear to be experts on old tub rims... campy record crono.... advice? seller rekons they are 320g... true? they are 24h, will they be way too light? why are rims not made this light anymore? would be interesting to build up w/ a record hub and m5 front (radial), i'm about the same weight as the OP...
