Thorn Forum Member Frame-size Registry: Who fits what
« on: December 01, 2012, 09:17:01 pm »
Hi All!

We've each purchased a Thorn -- or might wish to -- and had questions as to which size is best. The topic arises frequently on the Forum, and (while Thorn do a great job of fitting people to bikes) it is sometimes reassuring to talk to an owner of similar size.

We comprise a sizable resource, and can help each other and those who follow if we compile a sub-registry of sizes.

If you own a Thorn and are willing to post as to...

• which model
• its size
• handlebar type
• your overall height in bare feet rounded to the nearest cm
• a note about any unusual fitting requirements...

...it might help others to see which combos go together. Specific queries could be made wrt leg length, standover, etc., but this would at least get the ball rolling in a single topic. While it would be nice to generate a whole table of sizes with full measurements, preferences, mods and a satisfaction index, just a simple listing should answer most of the questions that arise.

I'll start...

Thorn Sherpa Mk2, size 560S, drops, my height 5'11"/180cm. *Note: uncut steerer, long-layback seatpost (no longer owned).
Thorn Nomad Mk2, size 590M, drops, my height 5'11"/180cm. *Note: uncut steerer, long-layback seatpost (currently owned).

Best,

Dan.

Thorn Raven Tour 2009
Frame size 512L
Thorn Comfort Bars
My height 174cm

NOTE:
As I have fitted a SR Suntour SP12 NCX suspension post I rotated the comfort bars to be a little more vertical to compensate for slight reduction in handlebar to seat distance (about 1cm). The Sunrour post fits the brooks B17 saddle but space is tight resulting in little forward and backwards seat movement available.

I'm 167 cm short and my inside leg length in bare feet is 76.5 cm.

I have a Club Tour size 517L with dropped bars. Stem length 120 mm with 6 deg rise and 42 cm bars.

The chaps at SJS got it pretty spot on from the measurements I provided on line.

Cheers,

pj

• which model -  Thorn XTC
• its size - 525L
• handlebar type - drops
• your overall height in bare feet rounded to the nearest cm - 5 feet 5 inches, 165cm.
• a note about any unusual fitting requirements... longish arms/legs but short upper body.

Saddle all the way forward, 8CM reach mountainbike stem (with tilts upwards) and 38CM 3TTT ladies short reach drop bars (due to tiny shoulders)

Standover is fine at 77CM mid tube, but the top tube at 55.5 virtual is too long.
Hence the short reach bar (8 instead of usual 10) and saddle forward which saves another 2 cm and voila I am near the 51.5 top tube mark.

With a straight bar bike however I take a 54 cm top tube

(If I ever find time/love for another bike ;)

Pedal to the metal! Wind, rain, hills, braking power permitting ;)

Both 2012 Sherpa Mk2s

Steve: 560S, pro PLT shallow drops, B17 saddle on the standard seat post.
Height 180cm (5'11) with long legs (~33" IL)
I took two spacers off and turned the stem over to spare my lower back.
Gel padding under the bar tape
I refer to my Thorn as Erwin

Gill: 485L, Thorn flats with SJSC Ergo bar ends, Specialized Lithia saddle on the standard seat post.
Height 160cm (5'3) normal proportions
Gill has creaky wrists and says the flat bars are the most comfortable she has tried, she says her Thorn does not require a name .....

If the house were on fire I would save:  Gill, Erwin, my Guitar.
