we are changing the Crankset to a Triple, Alloy, 30/42/52 with 175mm crank arms, a 118mm alloy bottom bracket, a Shimano FD-R443 Front Derailleur and a higher quality KMC Z92 chain. She has on (permanent) loan a pair of Michie Pro Race red/black tyres, the bike looks stunning!

I found that out commuting to work several years ago, even when it was cooler weather, having the straps in direct contact and bearing weight. Makes even non-comfort bikes more comfortable!

PS: I am considering reviving the old Giant Sedona AL for future Munda Biddi segment day trips. Have to still get into commuting to work to increase fitness, probably get the project underway late July for regular weekend riding in Spring.

Re: Upgrades to entry level MTBs and Comfort Bikes

A friend of mine has given me his road bike

. I was going to get a hybrid. Are the changes much the same ? I'm thinking of changing handlebars, brake levers and not much else.
Any help would be greatly appreciated.

Today's example:
Giant Upland Ladies XS 14" http://www.giant-bicycles.com/au/03...007&model=10105
Fit Conti City Contact 26x1.5 Tyres and Presta Valve Tubes.
Swap Cassette to Sunrace 11-24 7 Speed.
Swap Crankset to 28/38/48 with 152mm Cranks.
Swap Pedals to alloy MTB and fit Strapless Toe Clips.
Swap Seatpost to Suspension Post with a reversable head.
Swap Stem to 90mm adjustable.
Cut bars to 540mm, fit Foam Grips and adjust lever reach.

The bike ends up lower, lighter and fitting a sub 5' lady rider very well and is considerably faster than the original at a fraction of the cost of a road bike.

Are you sure that you want to do that??

Which road bike is it? While a Giant OCR would be suitable for conversion to hybrid, a Cervelo TT bike might not be.

I am doing several Drop to Flat Bar Conversions at the moment.
Esentially:
Flat bars and Grips
Longer Stem to suit flat bars, (25.4mm x 100mm-110mm)
Flat Bar-Calliper Brake Levers, Shimano BL-R550
Flat Bar Shifters, SL-R440/443/A depending on 8,9 speed or a Double / Triple chainring
Flat Bar Front Derailleur, FD-R440/3/A/F depeding on 8/9 speed, Double/Triple Crankset, Braze/Clamp on mounting.

A typical current project below:

Velo Ladies Saddle with cut-out,
A longer, 100mm, adjustable stem,
Alloy Flat Bars.
In the performance department,
I recently fitted a 12-24 tooth 7 speed cassette, with 2 tooth jumps, Jackie says its much nicer to ride.

With 48-12 gearing she still tops out over 50Ks!

24" wheels with wide rims
14-28 6 speed spin on freewheel
28/38/48 one piece 140mm crankset.

Apart from some surface rust on the rims the bike is in good condition, so the plan is to mod it for a spare bike to for "Little Jackie" and her friends.

First thing is to service all the bearings and cables and then fit:
152mm one piece crank arms,
small strapless toe clips for the pedals,
foam grips for the bars,
24x1.5 Duro City Tyres and tubes,
Suspension seat post, 25.4, with reversable clamp,
Ladies Velo saddle.

More later as the parts arrive...

Jackie has lent me the Huffy!

See Posts 62-68 for original story and pix; http://www.cyclingforums.com/t-363004-15-4.html

Now that's a dangerous thing to do to a bike mechanic:
First, remove all Huffy stickers, replace with K-Mart Stickers.
Remove 24" wheels and Tyres, replace with 26" wheels and 85psi tyres.
Change brake callipers to 60mm drop.
Change the flat bars to 580mm bars with a 30mm rise.
Change brake levers to the four finger variety.
Remove the stand and steel bracket (angle grinder) from the chain stay, the 26" wheel now fits in easily!
Change 152mm One Piece Crankset to 170mm.
Change 28/38/48 chainwheels to 36/42/48 teeth.
Change the seat to a Selle Italia comfort saddle.
Fit Alloy Front Rack. (looking for cane basket)
