|Race tubular wheelset||buffalosorrow|
Jan 9, 2003 3:39 PM
|For next season I wish to save for a tubular wheelset.
I was considering the mavic relfex cd ceramic 32h with record hubs.
My question is regarding the use of 28h rims and corresponding record hubs, will I end up truing the 28h more times than the 32h? I am a light rider 140lbs. I feel that I should stay put with 32h.
And what other options do I have regarding tubular rim selection?
Finally what spoke build and guage should I consider? 3x overall, 3x drive and 2x non-drive.

|I prefer strength so I'd say 3x. at your size a handbuilt 28 spoke wheel laced 3x should work. Shy from radial lacing. 3x will provide the strongest, most hassle free wheel. Reflex will do fine, find out if Velocity makes an aerohead tubie|

|Velocity makes two different road tubular rims, the Escape which has a somewhat similar section to the Aerohead, and the Pro-Elite which looks more like the Fusion or Deep-V clincher.
Velocity's US website only lists the Escape, so I'm not sure the Pro-elite is available over here. Their Aussie site shows both, although with suprisingly little detail.

|Fir makes its SRG 30 (30mm depth) in both clincher and tubular versions. I raced a set of the tubulars with a set of challenge grifo (30mm) tires at pressures as low as 35lbs, without a single touchup or retrue. They are not light for a tubular rim (app. 520grams) but they are strong, arrow and shed mud relatively well.
Any bike shop that deals with Red Rose imports (Moser, Olmo) etc. should be able to get them.

|From what I have collected, the mavic reflex CD ceramic is the lightest @ 380 grams per rim.
The Velocity Escape mathces the weight of the reflex at 380g.
Although the pro-elite weighs 500g and deep V 520g
The Fir SRG- 30 looks of a quality rim but also weights 500g.
I am not a weight weenie, but why is there not a middle ground? Well there is the Campy moskva's clinchers that I am running now, they surprised me when I found that they weighed 435g. I suppose ideally I am looking for a moderate deep dish (28mm) durrable rim that weighs 400 grams. I understand that the 'V' rims carry more material, hence weight.
Might anyone know if campy made the Moskva in a tubular format? I think they are great wheels,I would/ have raced them solo. Next season I am going to race basically every weekend between NJ,CT and NY. I think I would benefit from a new wheelset and the Moskva's (with tubular clinchers) as spares or other way around.
Thanks for the information.

|I have not used the tufo tubular clinchers, but I can say that once you try real tubulars on a cross bike you will not want to race anything else. You can run much lower pressure without fear of pinch flating. They feel smoother and faster in the rough stuff, and let you be more agressive over obstacles. For example the local race last weekend had two telephone poles that had to be crossed at angles. Although everyone was bunny hopping them, I had a definite advantage on tubies. They had to be careful, where as I was basically just letting it rip.
I went aero tubbie (SRG 30) over box rim for two reasons (1) strength (they must be idiot proof if I have had no problems; no one will confuse my technique with Johnathon Page) and (2) the aero rims have a taller side wall that make brake adjustment much easier (yeah I am lazy). People do run reflex tubular rims (with success), but the sidewalls are only about 11mm high and cantilever adjustment although not impossible is exacting. I also think they look cooler.
I don't have any ideas on a medium weight or depth (ie semi aero) rim. Campy has apparently stopped selling rims in favor of wheels only. Tubies in general, as you are no doubt aware, have fallen from favor.

|The tubular clinchers are in essence tubulars with a rubber gasket that hooks onto the clincher rim, no glue, no installation time, easy changes, tubular performance (low pressures) and no roll offs.
The only downside may be the extra weight that the rubber gasket places. I raced a half of a season on them, my first season, never had any wheels, tire problems. I have even started to ride them on my commuter SS cross.
I did notice at the race some people had comments regarding tubular clinchers, not sure if it was good or bad. "Those are tubular clinchers...(smirk)"
That same race a rider had a tubular roll off, I aked what happened and he said he could not afford a spare wheelset, while carrying his bike.
Perhaps sticking with tub/ clinchers offer the most flexibility? The only thing I have hesitation about is their avaialbility on the future.

|I think tubular clinchers are great, hell, they get me to victory today. BTW: My very first! They are a little heavy, but are just like the real thing. Last year I used tubulars, this year tubular clinchers, and I can't tell the difference except no more glue!!!!|

|I'm making the change as well. This weekend I pinch flatted a quarter of the way into the bell lap (after 2 of us had dropped the rest of the field by over a minute) in an attempt to pass in a fairly rocky section. Rode the rest of the lap on a flat front (pit was near start/finish) went from guaranteed 1st or 2nd to fourth. So frustrating, was having a great race. A bunch of guys who race our series ride the Tufos and I've only seen 1 come off the rim. The Tufo guy was there at the race and I bought a set of Tub/Clinchers (on sale even!) will race them next year. May swap other rims for veed tubbies and go all the way with other bike. Never want that to happen again. I'm a bigger rider so I pinch flat easier and am forced to run higher pressures. I was running 30 Mich Muds at 68 psi and still flatted.|

|correct me if I'm wrong, but that is NOT good for a course with any sort of mud or gravel.|
Jan 13, 2003 8:18 PM
|no it is not. Unfortunately at 230lbs I don't get to make tire pressure decisions based on such things. If there is any rough or rocky terrain I must run high psi to avoid pinch flatting. I lose traction but I don't flat. This weekends course was typical Sandy Eggo. Dry, powdered clay, on stone. Dirt is like talc with babyheads sticking out. Softer pressure and I bottom rim out often. If course is 'soft' by my standards I'll go down to 55psi, rarely lower. I caught a babyhead with an edge a quarter of the way through the last lap and pinched my front wheel. Total drag. I lost 2 places and crashed twice trying to race on a flat front tire, this is why I'm switching to the Tufo's. I may take bike #2 and rebuild wheels with tubie rims so I can run the Tufo 34's.
Then I can be Mr. 40 psi too.

|I heard you can ditch the rim tape, are you doing this?
I have not yet.

|yes you can. but if you do, you can't replace with a clincher.
will do on my race wheels
|Tufo LPS tires and good handbuilt wheels||TB|
Jan 20, 2003 6:47 PM
|Forget the tubie/clinchers, for tires the Tufo LPS can not be beat. I have run these tires as low as 25 psi on a sandy beach course with no problems. Forget about glue too. Use the Tufo tubular mounting tape. Its easy to put on and locks those tires on tight. No rolled tires here. The LPS version of the tire is about $20 more but the ability run those super low pressures make it the choice. The other big advantage to the Tufos is the the ability to seal them back up when you get a flat. The Tufos arent like other tubulars. They don't really have a tube inside. The whole tire is one bonded unit. Tufo sells this latex stuff you squirt inside and it seals up the flats. Alot like Stan's NoTubes stuff. I usually put half a tube in new tires and then I have some flat protection sort of like slime. While tubular purists my say they don't ride as well as a hand made tire, they still ride a whole lot better than clinchers. Stu at www.cyclocrossworld.com has all of this Tufo stuff at really great prices. He beats my LBS price on the tires by $30.
For wheels, I have been riding Mavic Classics for a number of years. They have basically a Mavic Reflex rim laced 3x to a mavic hub. I have been very happy with these over the years. i don'tthink Mavic makes them anymore, but you can find them on eBay from time to time. When I can't get the Classics anymore, I will be going with handbuilts with Mavic Reflex rims. I only weigh 140lbs and have never had trouble with wheels, so I would think a good handbuilt wheel 32 spokes 3X will be great. www.cyclocrossworld.com sells some Dura-Ace/Reflex wheels for $350. I would think at 140lbs you could get away with riding most any wheelset. Alot of the pros are riding carbon wheels these days, and you are seeing wheels like Ksyriums out there too. FOr those of us who pay for our own equipment though, I would think handbuilts are they way to go.
