    R20 451 wheels

    Been using Velocity 451 rims for a few years now with Schwalbe Stelvio tyres on two of my R20s. While they work well, I'm not convinced they're the best size to use. The tyres are quite difficult to mount and not easy to find when on tour. I've considered buying 451 Kenda Kwests but would like to know if anyone has problems mounting these too.

    I'm also using Velocity 406 rims on another R20 with Conti slicks or Primo Comets and they perform very well.... a 6:15 100 mile hilly ride on a SS R20 shows that. I'm tending to think this size might be better all round, in terms of more tyre choice and overall availability.

    I prefer the look of 451, but are they worth the hassle?



    If any Aussie R20 owners are interested I have a set of new/never used Velocity 451 rims for sale.
    Front is 36h with new Shimano Deore hub.
    Rear is 36h with NOS Sach 3x7 hub with toggle etc.
    I'm lame,
    I'm sore,
    I'm stonkered.

    You can get Primo Comets in 451 also.

    You can get a decent idea of what is out there via ...

    www.calhouncyclery.com

    They are known for have an excellent selection of tires. The recumbent guys have also talked about a Panaracer 32-351 tire (from memory) in a positive manner.

    Personally, I would try out the Primo Comets -- great tire at the price, IMO -- before switching to 406. The Primo Comet also comes in several widths including the widest 451 tire that I know of ... 37 mm.

    I've found that ebay, despite it going to the crap shoot, still has many shops that carry 451 sized tires, mainly primo comets and schwalbe stelvio/durano.

    I bought a pair of duranos for $60 shipped from the UK. not a bad price.

    Sounds like you guys want me to stick to 451, thanks for the tyre recommendations.

    I really like the performance of the Stelvio but found while the wire bead ones were hard to mount the kevlar bead folding tyres were nigh on impossible to mount.

    Do you find that Primo Comets wear too quickly?

    I think the Comets last just fine, and I'd recommend going with the Kevlar rather than the regular model.

    I advise against the Kevlar ones - the kevlar does not seem to prevent punctures for me but they cost more.

    I am actually looking for a set of 451 wheels.

    there are some quite cheap velocity rims you can buy off of ben's cycle vendio or ebay store.
    might not come in the colour you want, but plenty of drilling selection.

    example:
    ebay shimano 36h 105 hub, ebay 36h synergy rim and ebay tire...
    spokes I had cut locally.

    I built a set of Alex 451 R390's for my Mu Duo .. I've been happy with the Stelvios .. they go on and off pretty easy.

    Bruce, those Alex rims look good.... must be that the Velocity Aero rims are slighty larger 'cos after many years of "tyre/tire changing" experience these are the worst I've ever come across, that includes 700c Contis on steel rims.

    If I remember correctly, Jur, you wanted 32h? These are 36h with the Sachs 3x7 hub, but if you're interested I'll include the toggle, pin and gear adjuster.
    PM me if you like.
