Functional bikes. Not Porn not Anti

no brixton… spotted you at balham waitrose before!!

That what I was thinking of;

functional bike folk

what's a better choice for a rugged tourer with cx leanings that will be used on a variety of surfaces, from road to gravel to sand to (less frequently) mud:

• 29er rims
  
• 700c touring rims
  
  

What tire options do you have with 29ers?

It's to go on a steel frame and i'd want proper mudguards on there too. Planning the order / purchase for mid summer. It's going to be a custom build so space could be built in, but is there a limit to this stuff? would 32s be the biggest tire you'd go for? is there a good website for this sort of info? i've been looking at other forums and threads but not found anything definitive.

The reason i was thinking 29er rims is to get something naturally bomb proof without having to build in bomb proof on normal 700cs by going crazy on spoke count.

^ to give you an idea of what I want to have built, basically something with the capability of the Salsa Vaya http://salsacycles.com/bikes/vaya_3/

Will you be using rim brakes?

I think you'll struggle to find many (if any) 29er rims that aren't disc specific.

I'd go with Velocity dyad if you're using rim brakes.

See: http://twentynineinches.com/2009/01/15/question-can-you-put-road-tires-on-a-29er-rim/

There's an article somewhere about using road tyres on 29er wheelsets, and there's also the sheldon brown tyre table. From memory I think you'd be fine using anything +28c.

i am going for 29er rims on the commuto x bike, as it will have disc brakes

they may also be used on one of my 29ers too

Have you had a browse of Singluar bikes?

It sounds like you're after something like a peregrine: http://www.singularcycles.com/shop/index.php/frames/singular-peregrine.html

So check out how they have been designed. Also a couple of people on here have had them so maybe search for them and drop them a message re tyre size/mudgaurds etc.

cheers guys - i'll be running disc brakes on it so braking surface not an issue.

i'll check those links

in which case look at the hope hoops 29er wheels, great value for what they are - you would struggle to buy the parts cheaper than the complete wheelsets

I'm not sure a 29er rim is going to be much stronger than a touring rim. One thing to consider is that for a wheel to carry more weight (touring), is might need higher spoke tension. Touring rims are designed to cope with this. Saying that. The DT swiss 29er rims I posted up thread are claimed to withstand increased spoke tension. So are probably perfect.

The advantage is in rim width, which gives a better profile.

With those I wouldnt go below 25mm. 28mm maybe. If you are lucky you could fit a pair of skinny 29er xc tyres. The upper limit depends on the frame TBH.

^ he's also trying to work out what size to work out what size tyres to plan for on a custom frame I think.

thanks for the advice.

yep, as hugo7 says it's all around getting my thoughts together on requirements for a custom frame / complete bike build. the guy (angus taylor of taylormadebikes.co.uk) will also build wheels for it within my (actually not that great) budget, and once i've got some money together we'll no doubt have a proper conversation about demands on the wheels and relative merits of 29er vs 700c and tire widths, but i prefer to go into that sort of conversation armed with a bit of knowledge in advance!

^ he's also trying to work out what size to work out what size tyres to plan for on a custom frame I think.

I guess I'd go with 32/35mm sliks + full mudguards, or 48.5mm (1.9") 29er tyres without. Whichever is biggest.

Having room for 32mm road tyres and full guards gives a nice road touring options.

Having room for 1.9" 29er tyres gives a decent amount of off-road tyre options. I'm not sure you'd find many specialist mud tyres in that size. But thats not what you want (I think). I would'nt limit myself to CX tyres. The pressures required to carry a heavy cyclist makes them less effective on a lot of surfaces (speaking from painful experiance).

I would base my descion on use.

A) heavy load carrying = high tyre pressure, and high spoke tension.

Both of which will reduce comfort. The solution is to increase tyre size, and preferably rim width. So a strong 29er rim (with regards to spoke tension resistance), and a fattish road slik. Say 32m/35mm.

B) Off-road riding = desire to increase contact patch.

This is best done by reducing tyre pressure. Which requires fatter tyres, and wider rims. If you want to aviod pinch flats.

I guess I'm saying. Go big!

lovely, cheers for that.

reckon it's possible to run treaded 29er rims with cx tires and full mudguards at the same time, or would it either / both clog up the guards with crap from the tires and stop the wheels moving / require silly geometry?

This bike is running 1.9" bonty XR1s. As you can see you'd need a lot of clearance to fit full guards. Especially with decent mud clearance.

Running those tyres with full mudguards seems a bit sillly to me. I was merely pointing out that if it was my frame. I'd like the option to set the bike up monstercross style on occasion. Whipping the guards off, and wacking on some decent off-road rubber. Once the mudguard stays are cut and adjusted. Its a quick job to fit them again.

A everyday, jack of all trades set-up (for me), would be some 35mm Kenda small block eights, and full guards. But then I like to take gravel paths, and surfaced mountain trails as much as possible.

That what I was thinking of;

Do you ride past Vauxhall in mornings? I think I paid you a 'nice bike' compliment a couple of weeks ago. I hope you use another lock and not just the above if it's alone regularly.

If you're limiting yourself to 32mm, no point in going with 29er rims, unless you find something cheaper than 700. Velocity and Sun/Ringle provide some decent options for a reasonable price.

Trigger pulled on the lynskey

Eta late July, they are due to start building the next batch in a couple of weeks time

nice one, look forward to seeing the final product

I'm not sure I'd agree with this. Disc specific 29er rims are often lighter and the extra width does no harm.

My plan is for the hope hoops stans 29er wheels

For weight to strength they seem pretty hard to beat, plus they can be migrated to one of my actual 29ers too.

possibly, ha ha about that lock it does look feeble, think I was shopping for heavy stuff and didn't want to carry 2kg of yellow lock as well.

I'd like to believe that my statement preceded the disc-specific preference.

How awesome is this?

I'd like to believe that too but it didn't (see the 1st post on the page).
