27.5 (650B). Wheels & Tyres sizes?

[Moss]

Sorry this isn't actually a Retro question.

I've bought myself a Giant Talon 2, A 27.5 (650B ) model. The tyres are Schwalbe Rapid Rob 27,5 2.25.. I ride XC and Tarmac trails and country lanes and some fire roads. I don't really need these off road MTB tyres! Does anyone know of a narrower tyre with a lot less knobbly tread, available in the new 27.5. Wheel size?. Any help appreciated.
Thanks

Re:

There's a search doohickey on Schwalbes site: http://www.schwalbe.com/gb/reifensuche.html, you need to look for ETRTO 584 for 650B/27.5.

I was going to suggest Sammy Slicks, I have them on one of my bikes and they're great on tarmac, towpaths and dry trails, not too heavy and fairly puncture resistant, but sadly not available in 650b. Most of the 650b off-road tyres, by Schwalbe at least, are pretty fat and knobbly. They make some narrower touring tyres, like the Marathons in 650b; I have some 26x1.75 Marathon Plus on another bike and they're great, last forever and never get punctures, but at nearly a kilo each, they're a bit weighty.

Thanks,! I'll have a look at the Schwalbe tyre..

Others to consider from the SJS Cycles site:

Its important to remember that 650B is not a new wheel size just one thats been repurposed for mtb. The size is basically that, that was found on French touring bikes from the past and thus touring tyres are available.

I think it was also used on some small road racing bikes as well, made for shorter people, where 700c wheels were just too large to make a well proportioned frame and sometimes for the front wheel on time trial bikes to get a really low front end, or where they 650c? :?

There's a bewildering number of bicycle wheel rim sizes, but regardless of fashion and supposed handling and rolling merrits, you can't beat ye classic olde 26" (ETRTO 559) rim for tyre choice.

650b for tourers and scandanavian workbikes/commuters ?, 650c for road bikes and time trials. Oh and in case anyone wants to know what 650a (ETRTO 590) is, thats very common in UK as its 26 x 1&3/8th inch 3 speed roadster wheel size though also standard for bicycle speedway.

I often find it surprising the style of tyres you can source with a bit of effort. Knobbly tyres are available for 20 x 1&3/8", 26 x 1&3/8" and 27 x 1&1/4" which are all old school brit sizes. Its even possible to get 28 x 1&5/8" knobbly tyres which are designed for lightweight carts that fit bike rims, thats 29er territory years before 29ers :roll:
